The Atom
The subatomic particle with a charge of +1.
What is a proton?
Avogadro's number.
What is 6.02x1023?
The rule that states that all atoms want 8 electrons in their valence shell to be stable.
What is the Octet Rule?
This family contains very reactive nonmetals that exist at all different states of matter. They all gain 1 valence electron to be stable.
What are the Halogens?
Do substances with ionic bonds tend to have a high boiling point or a low boiling point?
High boiling point.
This subatomic particle differs between isotopes of the same element.
What are neutrons?

What is sulfur?
The element with the most ionization energy out of the following group of elements: Be, Mg, Ca.
What is Be?
The chemical formula of potassium phosphide.
What is K3P?
The type of ion that is formed when an atom gains electrons.
What is an anion?
