covalent bonding (small covalent molecules)

Question 1

what is a covalent bond?

Answer 1

a covalent bond is formed when a a pair of electrons is shared between two non metals

Question 2

the attributes of small covalent molecules

Answer 2

have low melting and boiling points
are usually liquid or gas at room temp

Question 3

the atoms in each molecule are held together by

Answer 3

strong covalent bonds

Question 4

what is an intermolecular force

Answer 4

they are VERY WEAK forces in-between molecules (not atoms)

intermolecular - between forces

Question 5

as the intermolecular forces between the molecules are weak,

Answer 5

it does not take much energy to break them.

Question 6

The bigger the covalent molecule, the stronger the

Answer 6

intermolecular forces are, and so it requires more energy to break

Question 7

small covalent molecules do not conduct electricity —>

Answer 7

as the molecules do not have an overall electric charge (no free electrons or ions)
