Answer 1

First two columns are S1, S2. Next are d1 - d10 and then p1- p6. S columns are numbered by row 1-7. D columns are numbered 3-6. P columns are numbered 2-7.

Question 2

Ionic bond?

Answer 2

Strongest electronegativity is greater than 1.7

Question 3

Polar covalent bond?

Answer 3

Electronegativity is between 0 and 1.7

Question 4

Covalent bond

Answer 4

electronegativity is 0

Question 5

Rank single, double, and triple bonds

Answer 5

Single = weaker, longer, less bond energy
double =
Triple = Stronger, shorter, more bond energy

Question 6

Rank σ, π, ς

Answer 6

σ = Good overlap, stronger bonds
π
ς = Poor overlap, weaker bonds
