# Do isotopes of the same element have the same atomic mass?

## Do isotopes of the same element have the same atomic mass?

Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.

### Do isotopes have the same number of protons but different atomic mass?

Two atoms with the same atomic number, but different mass numbers (same number of protons, different number of neutrons), are called isotopes, or isotopic nuclides. Having different numbers of neutrons changes the mass of these atoms, so isotopes have slight variations in their physical and chemical behavior.

What has the same number of isotopes?

Isotopes have same atomic number but different mass number. They have same number of electrons and same number of protons but different number of neutrons. For example, two isotopes of chlorine have mass numbers 35 and 37.

How are isotopes of the same element alike?

Different isotopes of the same element have the same atomic number. They have the same number of protons. The atomic number is decided by the number of protons. Isotopes have different mass numbers, though, because they have different numbers of neutrons.

## Do isotopes have same number of electrons?

Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons.

### Does mass number change in isotopes?

Isotopes are atoms that have the same atomic number but different mass numbers due to a change in the number of neutrons.

Which of the following is the same for all isotopes of an element?

Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2). Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers.

Can two isotopes have same number of neutrons?

The number of neutrons can be different, even in atoms of the same element. Atoms of the same element that contain the same number of protons, but different numbers of neutrons, are known as isotopes.

## Do isotopes have the same number of electrons?

### Why do isotopes have the same number of electrons?

While isotopes has different numbers of neutrons, massive, neutrally charged, nuclear particles, they have the same number of protons, massive, positively charged, nuclear particles. And the neutral atom has therefore the SAME number of electrons, as the isotopes of a given element.

How many electrons are in an isotope?

In a neutral isotope, the number of electrons equals the number of protons. Like finding the number of protons, finding the number of electrons in a neutral isotope requires finding the atomic number of the element.
