Activity 3 - Bonding of Atoms

Describe covalent and ionic bonding?
- Covalent - a chemical bond that involves sharing a pair of electrons between atoms in a molecule
   Ionic - a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion

What is electronegativity?

- the tendency of an atom or radical to attract electrons in the formation of an ionic bond.

List the electronegativity values for H, Na, Cl, and O.

- H = 2.1

  Na = 0.9

  Cl = 3.0

  O = 3.5
