Chapter 4 Notes – Atomic Structure
... Isotopes of an element have the same atomic number but different mass numbers because they have different numbers of neutrons. For example, every atom of oxygen has 8 protons. Some oxygen atoms have 8 neutrons and a mass number of 16. Some oxygen atoms have 9 neutrons and a mass number of 17. ...

... The shared pair of electrons in a covalent bond are rarely shared equally between the two atoms involved. One atom usually has a higher electronegativity than the other and thus attracts the electrons more strongly. This atom has therefore acquired an extra share of negative charge and begins to res ...
