Genral Review Flashcards
1
Q
 share valence electrons and also share chemical characteristics
A
Groups (going down)
2
Q
What is the trend for size on periodic table?
A
Down and left
3
Q
What is the trend for electronegativity
A
Up and right
4
Q
Electron configuration is….
A
Specific address of electrons
5
Q
Group ___ Will show up as both covalently or ionically bonded
A
7
6
Q
How do you determine if something is polar or nonpolar? 
A
Compare electronegativity
Then determine which direction it is pulling and if it cancels out
7
Q
Lewis structure checklist
A
- Atoms
- octet
- electrons
- formal charge
8
Q
How do you show residence structures
A
Brackets
9
Q
What influences residence?
A
Stability. Resonance will favor neutral over separated charges
10
Q
What are the rules for resonance structures?
A
- octet
- atoms holding charge (charge for more electronegative atom)
- minimize separation of charges
