200

Each element in the same ______ has the same number of Valence Electrons.  

What is Group
200

Elements in this category will form anions. 

What is non-metal.

200

All atoms want _____ valence electrons to be stable. 

What is 8. 

300

As you go down a periodic table, the atomic radius of the elements will _____?

What is increases

300

Oxygen, Carbon, and Helium all belong to this category of elements. 

What is non-metal 

300

The radius of an atom will decrease across the periodic table due to the atom having more of these. 

What is protons

300

Elements in this group have one valence electron. 

What is group 1. 

400

Rank each element from smallest to largest atomic radius: Magnesium (Mg) Sulfur (S) Chlorine (Cl)

Chlorine Sulfur Magnesium

400

Sodium, Beryllium and Lithium belong to this category of atoms. 

What is metal 

400

Radius of an atom will increase in size as you go down a group on the periodic table due to the atom having more of these. 

What is electrons or electron rings

400

This group of elements have 8 valence electrons and  because of this, they are very unreactive.
