bonds characteristics (unit 4)

Question 1

covalent bond properties

Answer 1

• non-conductive
• weaker/ less brittle (no lattice structure)
• gas @ room temperature
• not conductive/soluble
• polar: medium boiling/ melting points (partial charges - more attraction)
  -slightly conductive/soluble in water (because of partial charges)
• non polar: weak melting/boiling point (no partial charges- no attraction)

Question 2

ionic bond properties

Answer 2

• brittle (lattice structures), crystalline
• high boiling/ melting points
• some conductivity
  -relatively strong
• full charges allow conductivity in water
• solid @ room temp

Question 3

metallic bond properties

Answer 3

• sea of electrons
• form rigid structures
• pliable, plastic (bendable, not brittle)
• high boiling/melting point (strong bonds)
• highly conductivity
• not soluble ^^^
