Front

What is the definition of an ionic bond?

Back

An ionic bond is a chemical bond formed between two ions with opposite charges.

Front

What is the octet rule?

Back

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

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat.

Front

What are the properties of metals?

Back

Metals are typically hard, malleable, ductile, and good conductors of heat and electricity.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom or ion.
