Ions and Isotopes

Front

What do isotopes of an element have in common?

Back

Isotopes of an element have the same number of protons but different numbers of neutrons.

Front

What is an isotope?

Back

An isotope is an atom of an element that has the same number of protons but a different number of neutrons.

Front

How do you calculate the mass number of an atom?

Back

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

Front

If an atom has 10 protons and 9 neutrons, what is its mass number?

Back

19 (10 protons + 9 neutrons = 19).

Front

What type of bond is formed between two nonmetals?

Back

A covalent bond.

Front

In a covalent bond, what happens to electrons?

Back

Electrons are shared between the atoms.

Front

What is the charge of a proton?

Back

Front

What is the charge of a neutron?

Back

A neutron has no charge (neutral).

Front

What is the charge of an electron?

Back

An electron has a negative charge.

Front

What is the difference between an ion and an isotope?

Back

An ion is an atom that has gained or lost electrons, resulting in a charge, while an isotope is an atom with the same number of protons but a different number of neutrons.
