What is an atom
Smallest building block of matter
100
Atoms are made of three main parts. Protons, Electrons and Neutrons. Where do they reside in an atom?
Protons and Neutrons in the Nucleus. Electrons around the outside.

What does neutral mean?
No charge - positives = negatives
200
What number on the acidity scale means neutral?
7

What is an element? DOUBLE JEOPARDY!! - What defines which element an atom is?
The name given to one type of atom DBL - The number of protons
200
What is the charge on the three parts of an atom?
P = + E = - N = o
200
What does stable mean? (in relation to ions)
The atom has a full outer energy level of electrons.
300
What numbers mean acidic AND basic? Be very precise!
Acid = 0 - <7 Base = >7 - 14
300
Acid + Carbonate -->
Metal Salt + Water + Carbon Dioxide
