Atomic Structure
What subatomic particles of the atom are in the shells (outside)?
What are electrons?
What does the atomic number (top number) of an element show you?
What is the number of protons?
What are electrons in the outermost shell called?
What are valence electrons?
Can two atoms with different numbers of electrons be the same element?
What is yes?
For each of the following scenarios, state whether the subatomic particles would attract or repel each other:
1) 2 protons
2) 1 proton and 1 electron
3) 2 electrons
What is 1) repel, 2) attract, and 3) repel?
What subatomic particles are in the nucleus (center of the atom)?
What is protons and neutrons?
What is the average atomic mass of an element called?
What is the atomic weight?
What do you call atoms with a charge (not neutral)?
What are ions?
Can two atoms with different numbers of protons be the same element?
What is no?
For group 14, how many "valence electrons" do these elements generally have?
What is 4 valence electrons?
Identify each of the three subatomic particles and their charges.

How many electrons can the FIRST shell hold?
What are 2 electrons?
What is lose electrons?
For groups 3-12, how many "valence electrons" do they generally have?

The number of protons plus neutrons gives you the...
What is atomic mass?
(Weight is INCORRECT)
What part of the periodic table tells you how many electron shells an atom has?
What are the periods/rows?
How many electrons can each shell (besides the first) hold and be considered full?
What are 8 electrons?
If you are an element on the right side of the periodic table, are you more likely to gain or lose electrons to become stable?
What is gain electrons?
What does an atom need to be stable?
What is a full valence electron shell?
In a neutral atom, the number of electrons should equal...
What is the number of protons?
What part of the periodic table tells you how many valence electrons an atom has?
What are the groups/columns?
When making an atomic model, before you add more electron shells, what must the inner shell(s) be?
What is full?
