Front

What is a cation?

Back

A cation is a positively charged ion that forms when an atom loses one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion that forms when an atom gains one or more electrons.

Front

Back

Al(MnO₄)₃

Front

What is the electron configuration for a bromine ion?

Back

[Kr]

Front

What is the electron configuration for a nitrogen ion?

Back

[Ne]

Front

What type of bond occurs between a metal and a nonmetal?

Back

Ionic bond.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.

Front

What is the significance of electron configurations?

Back

Electron configurations describe the distribution of electrons in an atom's orbitals, which determines the atom's chemical properties.

Front

How do you determine the charge of an ion?

Back

The charge of an ion is determined by the difference between the number of protons and electrons in an atom.
