Unit 1 - Covalent Bonding Flashcards
1
Q
Covalent Bonding Definition
A
The strong electrostatic attraction between 2 nuclei + the shared pair of electrons between them
2
Q
What bond is made if 2 electrons are shared ?
A
Single Bond
3
Q
What bond is made if 4 electrons are shared ?
A
Double Bond
4
Q
Dative Covalent Bonds (Coordinate Bonds) Definition
A
When 2 electrons that are shared, come from the SAME atom
It has a full outer shell
5
Q
Lone Pair Definition
A
A pair of electrons that are found in the outer shell but are not bonded to another atom
6
Q
Bond Length and Strength of a Single Bond
A
Single Bond C-C
- Longest
- Weakest
- 1 pair of electrons
- Electrons are not held tightly
7
