Ionic bonding

Question 1

What happens in ionic bonding?

Answer 1

Atoms lose/gain electrons to from charged particles, called ions, which are then strongly attracted to one another, due to their opposite charges. The 2 or more atoms are called a compound

Question 2

Atoms with almost [ ] outer shells like to get rid of their electron(s) and become ions ( + ). Atoms with almost full outer shells like to [ ] an electron(s) and become ions ( - ). Noble gases have a [ ] outer shell

Answer 2

empty
gain
full

Question 3

Ions like to latch on to other ions with an…

Answer 3

…opposite charge

Question 4

What do ionic compounds always have?

Answer 4

Giant Ionic Regular Lattices

Question 5

There’re very [ ] electrostatic forces of attraction between [ ] charged ions, in [ ] directions

Answer 5

strong
oppositely
all

Question 6

Ionic compounds all have similar properties, what are they and why? (3 and a half points)

Answer 6

1. High melting and boiling points - due to the strong attraction between ions. It takes a lot of energy to overcome the attraction
2. When they melt, the ions are free to move so they’ll carry an electric current
3. They dissolve easily in water - the ions separate and are free too move in the solution (so they carry an electric current)
