Types Of Bond

Question 1

Covalent bond

Answer 1

A bond between two non-metal atoms that share at least one pair of electrons.
Very strong bonds.

Question 2

Hydrogen bonds

Answer 2

Formed when there are electrostatic attraction between a proton in one molecule and an electronegative atom in another molecule.
Very quick to form and break. (weak)

Question 3

Ionic bonds

Answer 3

Bond between a metal and non-metal.
Formed when atoms donate or receive electrons from another atom to gain a full other shell.
Opposite electrostatic charges form on each atom.
Strong bonds

Question 4

Hydrophobic interactions

Answer 4

Very weak bonds between non-polar molecules as they try to avoid contact with polar molecules like water.
Easily broken.

Question 5

Disulphide bonds

Answer 5
