What are nonmetals?
What are solid, liquid, and gas?
The amount of space an object takes up.
What is volume?
These subatomic particles have no charge.

The nucleus is made up of these two subatomic particles.
What are protons and neutrons?
Exothermic reactions __________ heat into its surroundings.
What is release?
A vertical column of elements that share similar chemical properties.
What is a Group or Family?
A pure substance made up of two or more different types of atoms chemically bonded together in a fixed ratio (e.g. H2O)
What is a compound?
The shine of an object. A property of metals.
