Parts of the Atom
This subatomic particle has a positive charge
What is a Proton?
Does "Group" refer to vertical columns or horizontal rows?
What is vertical columns?
A neutral atom contains 7 protons, how many electrons must it have?
What is 7?
Group 2 elements have this many valence electrons
What is 2?

What is a Neutron?
The other name for a Group is
What is Family?
An element has an atomic number of 12, it must have this many protons
What is 12?
Valence electrons are those found in this energy level
What is the largest/outermost energy level?
Dull, Brittle, Not Ductile
What is a Non-Metal?
Protons and Neutrons form this part of the atom
What is the Nucleus?
What is Group 17?
An atom has a mass of 10 a.m.u. and contains 5 protons. How many neutrons must it have?
What is 5?
This rule for Group 13 - 18 elements allows us to determine the number of valence electrons in an element
What is ignore the 1 (or 10s place) and only look at the number on the right. Ex. Group 13 has 3 valence electrons
This category occupies the left side of the periodic table
What are Metals?
This subatomic particle is so small that it's mass is ignored in Atomic Mass calculations
What is an Electron?
This Noble Gas is found in Period 2
What is Neon?
A neutral element has an atomic number of 18, it must have this many electrons
What is 18?
Nitrogen (N) has this many valence electrons
What is 5?
This category of elements can be lustrous but brittle, often used as semi-conductors
What are Metalloids?
This part of the atom is where electrons orbit
What are Energy Levels/Shells?
An Alkaline Earth Metal can be found in this Group
What is Group 2?
An ion has a negative charge, what happened to its number of electrons?
What is gained electrons?
Helium is in group 18, it has this many valence electrons
What is 2?
This Non-Metal is unique as it does not live with the rest of the Non-Metals
What is Hydrogen?
