Covalent Bonds

A single bond is created when two atoms in a diatomic molecule share electrons in order to reach a full octet. Sometimes, in order to reach a full octet, atoms may have to share two or three pairs of electrons which creates a double or triple bond.

Explain how single, double and triple bonds form in covalent bonding. Please give explain in detail using proper grammar, spelling and mechanics.

Francium

Using your periodic table, which element has the lowest electronegativity?

calcium

Using your periodic table, which of the following has the lowest electronegavtivity?

2.1

What is the electronegativity difference between the following compound? NaCl

A polar covalent bond is when two atoms are not sharing an electron equally. A polar covalent bond is formed when the electronegativity difference is between .5 and 1.7. In a nonpolar covalent bond, the atoms share the electron equally. *What elements make polar and non-polar bonds*

Describe the difference in polar and nonpolar covalent bond in detail. Please use correct spelling, proper grammar and mechanics.
