Isotopes and Ions

Front

What is an Ion?

Back

An atom that has gained or lost electrons in an attempt to become stable or bond with another atom.

Front

What is a Neutral/Normal Atom?

Back

An atom with the same number of protons and electrons (no charge) and the expected atomic mass or number of neutrons from the periodic table.

Front

If an atom has 4 protons and 2 electrons, what is its charge?

Back

+2

Front

If an atom has a charge of -2 and an atomic number of 16, how many electrons does it have?

Back

18

Front

If an atom has a charge of +3 and an atomic number of 5, how many electrons does it have?

Back

2

Front

What defines an Isotope?

Back

Atoms of the same element that have the same number of protons but different numbers of neutrons.

Front

How does the charge of an atom affect its electron count?

Back

The charge indicates the difference between protons and electrons; a positive charge means fewer electrons than protons, while a negative charge means more electrons.

Front

What is the atomic number?

Back

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

Front

What is the mass number?

Back

The total number of protons and neutrons in an atom's nucleus.

Front

How do you calculate the number of neutrons in an atom?

Back

Subtract the atomic number from the mass number.
