200

What is the trend in atomic structure as you move down a group?

There is an increase in the number of PELs and shielding as you move down a group.

300

What is the oxidation number for the metal in an oxide with the formula MO₂?

+4

400

Which of the following is an unreactive element?

P  S   Cl   Ar

Ar

Group 18- Noble Gases- Unreactive

500

What is the trend in atomic structure across a period?

The number of protons increases (nuclear charge) which increases the nuclear attraction for electrons

(the number of energy levels (PELs) stays the same)

Ions

100

What is the total number of electrons in a fluoride ion (F^-) ?

10 electrons

200

What is the total number of electrons in a magnesium ion?

10 electrons

300

What is the Noble Gas that has the same configuration as the bromine ion?

Kr

Krypton

400

What is the Noble Gas that has the same electron configuration as the potassium (K) ion?

Ar

500

Is the the oxygen ion larger or smaller than an atom of oxygen?

Larger!  

The ion is  O^-2 and adding electrons causes the radius expand.
