Test 7- Intermolecular Forces Flashcards
1
Q
Name the compound
A
If metal and nonmetal - Name first element - Second element with -ide If 2 nonmetals - Name first element - greek prefix and ide on second one
2
Q
Determine the bond type (give the electronegativities)
A
- Subtract en
- nonpolar covalent- 0-0.4
- polar covalent- greater than 0.4 or less than or equal to 1.9
- Ionic if above 1.9
3
Q
Draw lewis dot diagram
A
- Higher EN goes in the middle
- Make sure each has 8
- H-2
- B-6
- Be-4
