REMEDIATION: Isotopes

Front

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, resulting in different mass numbers.

Front

How is the mass number of an atom calculated?

Back

The mass number is calculated by adding the number of protons and neutrons in the nucleus of an atom.

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

How many protons does titanium have?

Back

Titanium has 22 protons.

Front

What is the relationship between isotopes of the same element?

Back

Isotopes of the same element have the same atomic number (number of protons) but different mass numbers due to varying numbers of neutrons.

Front

How many electrons does a neutral atom have?

Back

A neutral atom has the same number of electrons as protons.
