Bonding

Question 1

What is an ionic bond?

Answer 1

electrostatic attraction between oppositely charged ions in a lattice

Question 2

formulas of compound ions

Answer 2

Sulphate ion= SO4 2-
Nitrate ion= NO3 -
Nitride= N 3-
Carbonate= CO3 2-
Sulphide= S 2-
Phosphate= PO4 3-
Bicarbonate= HCO3 -
Hydroxide= OH -
Oxide= O 2-

Question 3

Dative bond

Answer 3

shared pair of electrons with both electrons supplied by one atom.

Question 4

Formation of permanent dipole-dipole

Answer 4

The electron distribution in a covalent bond between elements with different electronegativities will be unsymmetrical. This produces a polar covalent bond, and may cause a molecule to have a permanent dipole.

Question 5

Dative bond

Answer 5

Forms when one atom donates both shared electrons in a bond/donates a pair of electrons in a bond

Question 6

Dipole

Answer 6

Difference in charge between the two atoms caused by a shift in electron density in the bond.
