A
Covalent
5
Q
Outermost electrons
A
Valence electron
6
Q
States that atoms tend to form compounds in ways that give them 8 valence electrons and thus the electron configuration of a noble gas
A
Octet Rule
7
Q

8
Q
A measure of from strongly atoms attract bonding electrons to themselves. The higher the electro negativity the greater an atom’s attraction for electrons
A
Electronegativity
9
Q
What are the rules in Electronegativity?
A
- If the (AEN) is less than or equal to 0.4, the bond is non- polar covalent
- If the (AEN) is greater then 0.4 but less than 1.9. The bond is polar covalent.
- If the (AEN) is greater than 1.9 then the bond is Ionic

11
Q
0.4 < 🔺EN < 1.9
A
polar covalent
12
Q
🔺EN > 1.9
A
ionic
