Bonding

Question 1

Electronegativity

Answer 1

The attraction of an atom for a shared pair of electrons in a covalent bond

Question 2

Atoms with a high IE also have a..

Answer 2

High electronegativity

Question 3

Polar covalent

Answer 3

One atom has slightly more attraction than the other

Question 4

Covalent

Answer 4

Both atoms have equal attraction

Question 5

Ionic bonding

Answer 5

When there’s a large difference in electronegativity -> electron transfer from the low E-neg atom to the high E-neg atom

Question 6

What is a covalent bond

Answer 6

The electrostatic force of attraction that the nuclei have for the shared pair of electrons

Question 7

What is special about phosphorus onwards

Answer 7

They can expand the octet

Question 8

What does VSEPR stand for

Answer 8

Valence shell electron pair repulsion

Question 9

VSEPR Theory

Answer 9

1. Pairs of electrons repel and take up positions as far apart as possible
2. There is an order of repulsion:
   LP-LP>LP-BP>BP-BP
3. Double bonds have the same repulsion as single bonds
