When drawing covalent bonds, what does a single line represent?
One pair of electrons being shared
If an electron is delocalized, what does that mean?
It does not belong to any single atom
When drawing covalent bonds, what does 2 parallel lines represent?

What is the name of a single covalent bond?
a sigma bond
When a double covalent bond is formed, one of those bonds is a sigma bond, what is the other bond?
A pi bond
What term is used to describe the amount of energy needed to break apart a covalent bond?
bond dissociation energy
Describe the properties of a metal alloy.
A metal alloy has the properties of all the elements that the alloy is composed of
What tells you how many covalent bonds an element will form?
The number of valence electrons it needs to reach an octet
As bond length decreases, what happens to the strength of the covalent bond?
It increases
When more electrons are shared (i.e. double vs single bond), what happens to the bond length?
It decreases
