Chapter 5 - Electrons and bonding

Question 1

Atomic orbitals

Answer 1

A region around the nucleus that can hold up to two electrons, with opposite spin. Shells are made up of atomic orbitals

Question 2

Ionic bonding

Answer 2

The electrostatic attraction between positive and negative ions. Holds together anions and cations

Question 3

Covalent bonding

Answer 3

The strong electrostatic attraction between a shared pair of electrons and the nuclei of the bonded atoms

Question 4

Multiple covalent bonds

Answer 4
