Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the significance of the periodic table groups?

Back

Elements in the same group have similar chemical properties and the same number of valence electrons.

Front

What is an alpha particle composed of?

Back

An alpha particle is composed of 2 protons and 2 neutrons.

Front

What is Boyle's Law?

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume at constant temperature.

Front

What does it mean for an atom to be neutral?

Back

An atom is neutral when it has an equal number of protons and electrons.
