Covalent Bonding Flashcards
1
Q
Covalent bonding
A
atoms of non metals share electrons that create molecules
2
Q
Needs and shares
A
An atom needs to share as many electrons as it needs to complete the outer shell
3
Q
Double bond
A
When there are 2 pairs of atoms to share
4
Q
How to know how many electrons and atom needs to share
A
8-group number
5
Q
Lattice structure
A
none, they form molecules
6
Q
Bond strength
A
The bond between the atoms’ nuclei is strong but the intermolecular force (more between the molecules) are weak
7
Q
Covalent properties
A
Simple molecules
Low melting+boiling point
usually not soluble in water
don’t conduct electricity except graphite
