What is an isotope?

Back

Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons.

Front

How do Neon-20 and Neon-22 differ?

Back

Neon-20 has 10 neutrons, while Neon-22 has 12 neutrons.

Front

What is the relationship between protons and electrons in a neutral atom?

Back

In a neutral atom, the number of electrons is equal to the number of protons.

Front

What happens if a proton is added to an atom?

Back

The atom becomes a different element.

Front

What is the atomic mass of an isotope based on?

Back

The atomic mass of an isotope is equal to the sum of its protons and neutrons.

Front

What is the mass number of an atom?

Back

The mass number is the total number of protons and neutrons in the nucleus of an atom.

Front

What is the significance of neutrons in isotopes?

Back

Neutrons contribute to the mass of an atom and can affect the stability of the nucleus.

Front

Can isotopes of the same element have different chemical properties?

Back

No, isotopes of the same element have the same chemical properties because they have the same number of electrons.

Front

What is the formula to calculate the mass number?

Back

Mass number = Number of protons + Number of neutrons.

Front

How does the presence of neutrons affect the stability of an atom?

Back

The presence of neutrons can stabilize the nucleus; too few or too many neutrons can lead to instability and radioactive decay.
