Answer : FI -- Polar Covalent because one of the atom is negative and other one is Positive
CsI -- Ionic Bonding -- One or more electron transferred between atoms
H2 -- Purely Covalent -- 2 electron equally shared between atoms.
2. What is the difference in electronegativity between the atom in HI?
Answer: 0.4 -- refer the table above I(2.5) - H(2.1) = 0.4
3. Which of the atoms in HI has a partial positive charge? Namely, when HI is placed in the electric field between two charged plates, which atom would point towards the negative plate? Write either H or I
Answer: H -- H+ and I-
4. How many valence electron does Boron have?

4. How many valence electron does Boron have?
Answer: 3
How: As you can see 13 above B means 3 valence electron, 14 above Carbon means 4 valence electron and so forth 5 for nitrogen, 6 for Oxygen, & for Fluorine, 8 for Neon.

Answer: 2 -- same logic as above.
6. How many valence electron does bromine have ?
Answer: 7
7. How many valence electron does argon have ?
Answer: 8
8. Which letter (a, b, c, d, e, f, g, or h) shows correct lewis structure for O?
Answer: F, because Oxygen have 6 valence electron.
9. Which letter shows correct lewis structure for S?
Answer: Same as Oxygen it falls under same column. F
