# Is the atomic number equal to the number of protons True or false? (2023)

## Is the atomic number equal to the number of protons True or false?

The atomic number equals the charge on the nucleus. It therefore also equals the number of protons in the nucleus and also equals numerically the number of electrons in the neutral atom.

Is atomic number equal to number of protons?

The number of protons in a nucleus is called the atomic number and always equals the number of electrons in orbit about that nucleus (in a nonionized atom).

Is the atomic mass equal to the number of protons True or false?

A mass number of a chemical element can be defined as the sum total of the number of protons and the number of electrons. For example, if we say the mass number of Oxygen is 16, we actually mean that the number of protons and the number of electrons in the oxygen atom is 16. Therefore, the given statement is true.

Is it true that atomic number equal to number of protons number of electrons?

Therefore, atomic number is equal to number of protons or number of electrons.

Does the atomic number equal the number of protons and neutrons?

The atomic number is the number of protons in an atom, and isotopes have the same atomic number but differ in the number of neutrons.

What is the atomic number equal to?

atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number.

Is the atomic number equal to the number of proton in the nucleus or?

Atomic number is the number of protons present in the nucleus of an atom of an element. Example: The nucleus of hydrogen atom contains 1 proton and hence, the atomic number of hydrogen is 1. The nucleus of carbon atom has 6 protons and hence, the atomic number of carbon is 6.

Is protons also equal to the number of electrons True or false?

All proper atoms have equal number of protons and electrons ie, all non-ions have equal number of protons and electrons. However when an atom is ionized by removing one electron, then it is positively charged and has one electron less than proton.

Is an atom has equal number of protons and electrons True or false?

This is because in an atom the number of electrons is always equal to the number of protons to maintain neutrality. The mass number is equal to the sum of protons and neutrons.

What is a proton equal to?

proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 1027 kg, which is 1,836 times the mass of an electron.

## Why atomic number is equal to the number of protons and not electrons?

The number of protons is generally equal to the number of electrons. The number of protons does not change. But the number of electrons can change if the atom loses or galns electrons. Therefore the atomic number of an atom is the nubmer of protons and not the number of electron.

Is the atomic number equal to the number of neutrons?

To calculate the numbers of subatomic particles in an atom, use its atomic number and mass number: number of protons = atomic number. number of electrons = atomic number. number of neutrons = mass number - atomic number.

What is the atomic number equal to quizlet?

The atomic number is equal to the number of protons. The mass number is equal to the sum of the number of protons and the number of neutrons .

What is an atom with an atomic number equal to two?

Consider the element helium. Its atomic number is 2, so it has two protons in its nucleus. Its nucleus also contains two neutrons.

What is the atomic number known as ____?

The atomic number or nuclear charge number (symbol Z) of a chemical element is the charge number of an atomic nucleus.

Is the atomic number of an element equal to the number of protons in each atom quizlet?

The correct answer is A. The atomic number of an element is equal to the number of protons in the atom's nucleus.

Is the atomic number of an element the number of protons the element contains?

The atomic number (Z) of an element is the number of protons in the nucleus of each atom of that element. This means that the number of protons is the characteristic which makes each element unique compared to all other elements. Elements are different because of their atomic number.

What is the number of protons equal to quizlet?

In An Atom the number of Protons equals the number of electrons. Flashcards | Quizlet.

Is the atomic number of an element equal to the number of neutrons?

Number of neutrons in an atom is equal to atomic mass - atomic number.
