What is a chemical bond?

Back

A chemical bond is a lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds.

Front

What are the two main types of chemical bonds?

Back

The two main types of chemical bonds are ionic bonds and covalent bonds.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is a polyatomic ion?

Back

A polyatomic ion is a charged species composed of two or more atoms covalently bonded together.

Front

What happens when an atom loses an electron?

Back

When an atom loses an electron, it becomes a positively charged ion (cation).

Front

What is the formula for calculating the number of shared electrons in a bond?

Back

In a single bond, 2 electrons are shared; in a double bond, 4 electrons are shared; in a triple bond, 6 electrons are shared.

Front

What is the correct name for the compound AlPO4?

Back

Front

What is the charge of a potassium ion after losing one electron?

Back

The charge of a potassium ion (K+) after losing one electron is +1.

Front

What is the difference between ionic and covalent compounds?

Back

Ionic compounds are formed from the transfer of electrons, while covalent compounds are formed from the sharing of electrons.
