Metaliic Bonding

Question 1

What type of elements contain metallic bonding?

Answer 1

Metals

Question 2

Are the bonds strong or weak

Answer 2

Strong

Question 3

What’s the structure of MB
(Definition)

Answer 3

Metallic bonding is the electrostatic attraction between the positive ions and the sea of the delocalised electrons

Question 4

Melting & boiling points

Answer 4

High, due to the large amount of energy needed to break the strong metallic bonds except mercury

Question 5

Ruling of nuclear charge across

Answer 5

Across a period the nuclear charge increases causing the electrons to become strongly attracted to the nucleus. This means more energy is required to break theses attractions hence the higher melting and boiling points.

Question 6

Down a group

Answer 6

Shells increases meaning the outer electrons are further away from the nucleus therefore less strongly attracted. These weaker attractions require less energy to be broken hence the decrease in melting and boiling points
