C3 Structure and Bonding

Question 1

What is ionic bonding and why does it happen

Answer 1

When atoms transfer electrons
They do it to gain a stable electronic structure
Extra - they bond together because of electrostatic attraction (attraction of positive and negative)

Question 2

What is covalent bonding and why does it happen

Answer 2

When atoms share electrons

They gain a stable electronic structure

Question 3

Why does chlorine travel around in pairs and what is it called

Answer 3

Diatomic
Because they both have unstable electronic structure so if they each share one then each atom has 8 electrons in the outer shell

Question 4

Non-metals and metals tend to do what in ionic bonding?

Answer 4

Metals tend to lose electrons this means their over all charge is + (protons > electrons) the and nonmetals tend to gain electrons this means their overall charge is - (protons < electrons)

Question 5

What is a Dot and Cross diagram

Answer 5

A diagram to show to show electron transfers between atoms (with the dots and crosses representing electrons). Usually you only need to show the electrons in the outer shell. - see fig 5 pg 38-39

Question 6

Do metals or non metals covalently bond?

Answer 6

Non metals
