Chapter 6 - Chemical Bonding

Question 1

what are the properties of noble gases?

Answer 1

unreactive and stable. exists as individual atoms. do not combine with other atoms to form compounds. fully filled outer valence shell

Question 2

what is ionic bonding?

Answer 2

donate/receive electrons, metal + non-metals

Question 3

what is covalent bonding?

Answer 3

sharing electrons, non-metals + non-metals

Question 4

Cl^- did chlorine give away or gain electrons?

Answer 4

gain

Question 5

Na^+ did sodium give away or gain electrons?

Answer 5

give away

Question 6

properties of ionic compounds?

Answer 6

giant ionic lattice structures, hard but brittle, high mp and bp, soluble in water but insoluble in organic solvent. conducts electricity when molten or aqueous state.

Question 7

properties of covalent compounds

Answer 7

simple molecular structure (weak F.O.A between molecules), low mp and bp. insoluble in water, soluble in organic solvent, does not conduct electricity at all

Question 8

what types of covalent structures are giant covalent structures?

Answer 8

diamond, graphite, silicon dioxide (sand)
