Accepted Answer

8

Question 14

This element holds 8 valence electrons in its 3rd orbital.

Accepted Answer

Ar

Question 15

As we move across the periodic table from left to right, the elements become...

Accepted Answer

less metallic

Question 16

Nobel Gases ...

Accepted Answer

have a full outer orbital

Question 17

The number above F (9) on the periodic table tells us how many P+s in the element...

Accepted Answer

Each element has its very own number of P+s,, If an atom is neutral, the atomic # tells us the # of e-s, The # of P+ s distinguishes Gold(AU)(79) from Silver(Ag)(47), Changing the # of P+s, changes the identity of the element
