What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a nonmetal.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

Why do atoms form ionic bonds?

Back

Atoms form ionic bonds to achieve a full outer shell of electrons, which leads to greater stability.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to have eight electrons in their valence shell, achieving a stable electron configuration.

How many valence electrons does Sodium (Na) have?

Back

Sodium (Na) has 1 valence electron.

Front

What is the charge of a sodium ion (Na+) after it loses an electron?

Back

The charge of a sodium ion (Na+) is +1 after it loses one electron.

Front

How many valence electrons does Chlorine (Cl) have?

Back

Chlorine (Cl) has 7 valence electrons.

Front

What happens to the charge of an atom when it gains an electron?

Back

When an atom gains an electron, it becomes negatively charged and is called an anion.

Front

What is a cation?

Back

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

Front

What is the Lewis dot structure?

Back

The Lewis dot structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.
