What is the Group 14 also called as?
Another name for Group 14 is the Carbon family. The outermost shell electronic configuration of 14- Group elements is ns 2 np 2 . This indicates their tetravalent nature in an excited state.
The carbon family is also called the carbon group, group 14, or group IV. At one time, this family was called the tetrels or tetragens because the elements belonged to group IV or as a reference to the four valence electrons of atoms of these elements. The family is also called the crystallogens.
The metallic β form is stable above 13.2°C, and the nonmetallic α form is stable below 13.2°C. Lead is the only group 14 element that is metallic in both structure and properties under all conditions.

The group 14 elements are the second group in the periodic table's p-block. It is also known as the carbon group. Carbon (C), Silicon (Si), Germanium (Ge), Tin (Sn), Lead (Pb), and Flerovium (Fl) are members of this group. The general electronic configuration of the group 14 elements is ns2 np2.
Group 14 is the carbon family. The five members are carbon, silicon, germanium, tin, and lead. All of these elements have four electrons in their outermost energy level. Of the Group 14 elements, only carbon and silicon form bonds as nonmetals (sharing electrons covalently).
The carbon group is a periodic table group consisting of carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). It lies within the p-block. In modern IUPAC notation, it is called group 14.
The Group 14 elements tend to adopt oxidation states of +4 and, for the heavier elements, +2 due to the inert pair effect. Members of this group conform well to general periodic trends. The atomic radii increase down the group, and ionization energies decrease. Metallic properties increase down the group.
It includes Carbon (C), Silicon (Si), Germanium (Ge), Tin (Sn), and Lead (Pb). Mnemonic for Group 14: Chemistry Sir Gives Sanki Problems. Group 15 is known as the group of Pnictogens or Nitrogen group. It includes Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb), and Bismuth (Bi).

Which element in group 14 has the largest atomic radius?
Atomic radius increases down the group with an increase in the number of shells. So, among the given choices, tin (Sn) has the largest atomic radius.
Group 14 is also known as the carbon group. It contains carbon, silicon, tin, germanium, and lead. They have four electrons in the outermost shell. They form two types of oxides–monoxides and dioxides.
Physical Properties:
Group 14 elements are less electropositive than group 13 owing to their small size and high ionization enthalpy. Down the group, the metallic character increases. C and Si are non-metals, Ge a metalloid, and Sn and Pb are soft metals with low melting points.
Elements in Group 14 could lose four, or gain four electrons to achieve a noble gas structure. In fact, if they are going to form ions, Group 14 elements form positive ions. Carbon and silicon form covalent bonds. Carbon's millions of organic compounds are all based on shared electrons in covalent bonds.
Why are noble gases called noble? The noble gases are helium, argon, krypton, xenon, and radon, in order of their mass. They are called noble gases because they are so majestic that they do not react with anything in general. They're also known as inert gases for this reason.
Four valence electrons, Since all elements in group 14 have 4 electrons in the outermost casing, group 14 elements have a valency of 4.
Q: How does the electronegativity vary along the Group 14 elements? Ans: As we move down the group, the electronegativity decreases in general. The reason behind this irregularity is because of the filling of intervening d and f atomic orbitals. However, the electronegativity is almost the same from silicon to lead.
1 Answer. [SiCl6]2– does not exist due to steric crowding of surrounding atoms.
Hence carbondioxide is more acidic among group 14 elements.
Tin. Tin is a chemical element with the symbol Sn (for Latin: stannum) and atomic number 50. It is a main-group metal in group 14 of the periodic table.
Who found carbon?
Discovered: First isolated by H. Moissan in 1886 after 74 years of efforts by various investigators (The unknown element had been observed as a constituent of minerals.)
Solution : Lead (metallic character increases on going down the group).
Silicon. Silicon (symbol Si) is a group 14 metalloid.
Solution : General valence shell electronic configuration of group `14` elements is `ns^(2)np^(2)`.
Group 14 Elements also known as Carbon Family belongs to the p-block group in the modern periodic table developed by Dmitri Mendeleev.
catenation, chemical linkage into chains of atoms of the same element, occurring only among the atoms of an element that has a valence of at least two and that forms relatively strong bonds with itself.

The vertical columns in a periodic table which are organized on the basis of the presence of electrons in the outermost shell are termed as a group. The elements in the same group show similar properties due to the similar electronic configuration of their atoms.
Group 14 or the carbon group has 4 electrons in its outer shell and it will become more stable if it becomes 8. It is easier to share the electrons rather than gaining or losing its electrons.
Oganesson has the highest atomic number and highest atomic mass of all known elements. The radioactive oganesson atom is very unstable, and since 2005, only five (possibly six) atoms of the isotope oganesson-294 have been detected.
- Higher atomic size elements are placed in the end of periodic table.
- The alkali metals have high atomic sizes. 'Alkali metals' which are in the “first group” of the 'periodic table'.
Common characteristics of groups 14 elements are they form covalent bonds. Because carbon's electronic configuration is 1s22s22p2.
For example, each atom of a group 14 element has four electrons in its outermost shell and therefore requires four more electrons to reach an octet. These four electrons can be gained by forming four covalent bonds, as illustrated here for carbon in CCl4 (carbon tetrachloride) and silicon in SiH4 (silane).
Carbon exists in several allotropic forms. Graphite and diamond are examples of allotropes of carbon that have different properties. The atomic number of carbon= 6. It lies in the 14th group in the periodic table.
Group 15 elements are also known as pnictogens because in Greek pigeon means to cholk or stifle. In the absence of the oxygen, molecular nitrogen has this property. That's why group 15 elements are known as either nitrogen family or pnictogens.
The Group 14 elements tend to adopt oxidation states of +4 and, for the heavier elements, +2 due to the inert pair effect. Members of this group conform well to general periodic trends. The atomic radii increase down the group, and ionization energies decrease. Metallic properties increase down the group.

Thomson showed that there were more fundamental particles present in the atoms. Fourteen years later, Rutherford discovered that most of the mass of an atom resides in a tiny nucleus whose radius is 100,000 times smaller than that of an atom.
A homologous series is a collection of compounds with the same general formula that differ only in the carbon chain length. Compounds in a homologous series often have a fixed set of functional groups, resulting in chemical and physical properties that are comparable.
What is isomerism class 10th?
What is Isomerism? Isomerism is the phenomenon in which more than one compounds have the same chemical formula but different chemical structures. Chemical compounds that have identical chemical formulae but differ in properties and the arrangement of atoms in the molecule are called isomers.
As we know that the group \[12\] on the periodic table is called the zinc group. The elements belongs to the group \[12\] are zinc $\left( {Zn} \right)$, cadmium $\left( {Cd} \right)$, mercury $\left( {Hg} \right)$, and copernicium $\left( {Cn} \right)$.

So, group-16 elements are named chalcogens. Thus, the correct answer is (B). Note: Note that Polonium is the only radioactive element in the group-16 of the periodic table. Remember that oxygen, sulphur and selenium are nonmetals. Tellurium is considered as a metalloid.
