Term
What is the nucleus?
Definition
The center of an atom.
Term
What is an atom?
Definition
The smallest component of an element that still contains the chemical properties of that element
Term
What is an atomic number?
Definition
The number of protons found in the nucleus
Term
How is a compound different from an element?
Definition
An element contains only one type of atom.
A compound is 2 or more elements chemically bound together.

SO4
Term
What must a mineral contain to be in the Sulfides group?
Definition
the atom S (sulfur)
Term
Name one example from each of the six classes of minerals.
Definition

Carbonates - CaCO3 (Calcium Carbonate)

Halides - NaCl (halite/table salt)

Oxides - Fe2O3 (iron oxide)

Sulfates - CaSO4 (gypsum)

Sulfides - PbS (galena) 

Term
Name five properties used to identify minerals.
Definition

Luster, Color, Streak, Cleavage + Fracture, hardness, special properties

 

(must remember special properties) 

Term
What is density?
Definition
Density is how heavy something is in relation to its size.
Term
How do you find density?
Definition

Divide its mass by its volume

Mass = weight

Volume = how much space it takes up

 

1. Weigh it (Mass)

2. Drop it in water, measure the water displacement (Volume)
