Test 4

Front

State the differences in the way bonds form (electrons) between ionic and covalent bonds.

Back

Ionic = Fully transferred, creates charged ions.
Covalent = Shares electrons, creates a neutral bond.

Front

Which groups on the periodic table form ionic or covalent bonds?

Back

Ionic = Elements from the far left side, then the far right side. (Metals + Non-metals)
Covalent = Both elements from the right side.
(Non-metals + Non-metals)

Front

How many valence electrons are required for an atom to become stable?

Back

8 Valence Electrons (Octet)

Front

Predict atom charges/oxidation numbers: Group 1 forms what type of ion? Cation or Anion?

Back

Group 1 = +1, therefore cation (It has a pawsitive charge)

EX: Group 15 = -3, Group 16 = -2, Group 17 = -1

Front

What is the name of N₂O₅?

How many Nitrogen atoms?

How many Oxygen atoms?

Back

Dinitrogen Pentoxide

2 Nitrogen atoms

5 Oxygen atoms

Front

Why are atoms attracted to each other in ionic compounds?

Back

- They form oppositely charged ions.

Front

Why are the noble gasses the most stable elements on the periodic table?

Back

- They have completely filled outer electron shells. (8)

Front

What is the force that holds atoms together in a compound?

Back

- A chemical bond.

Front

Determining ionic formulas based on oxidation numbers (SWAP AND DROP):
What is the formula for Potassium Oxide?

Back

K⁺O⁺² = K²O

Front

Rules for naming ionic compounds:

Back

Write the name for the cation (+), then the name of the anion (-) with the suffix, "-ide" the roman numerals to indicate the charge of the cation if it has multiple oxidation states.
