2.21 - Bonding in Discrete Molecules Flashcards
1
Q
What is a discrete molecule?
A
An electrically neutral group of 2 or more atoms held together by chemical bond
2
Q
What term is interchangeable with ‘discrete’?
A
Simple
3
Q
How can covalent and polar covalent bonding be shown in discrete molecules?
A
By dot and cross diagrams
4
Q
How is a covalent bond shown in a dot and cross diagram?
A
By a pair of electrons in the area where the two atoms overlap
5
Q
What is the octet rule?
A
That each atom in a compound must have 8 electrons in order for it to be stable
6
Q
Does this apply to dot and cross diagrams?
A
No
7
Q
Why?
A
Because in compounds such as sulfur hexafluoride, the central atom would have 12 electrons, which goes against this octet rule
