Unit 3 Flashcards
1
Q
What is the Octet rule?
A
The tendency of atoms to react in different ways to achieve an outer (valence) shell configuration of 8 e- like noble gasses.
2
Q
Where is the octet rule most common?
A
Amongst groups 1A-7A elements.
3
Q
Do atoms close to 8 valence e- tend to gain or lose e-?
A
They gain e-
Gain e- = negative charge = anion
4
Q
Do atoms with 1 or 2 valence electrons tend to gain or lose e-?
A
They lose e-
Lose e- = positive charge = cation
