ionic bonding

Question 1

what is ionic bonding?

Answer 1

electrostatic attraction between opoositely charged ions (in a lattice)

Question 2

What do the positiveand negative electrons do?

Answer 2

Positiv e cation loses an elecron
the negative anion gains the electron
They are not shared!

Question 3

How does ionic bonding work?

Answer 3

-The giving atom loses a valence electron so it has a full valence shell but a positive charge.
-The gaining atom gains a valence electron so that it has a full valence shell but a negative charge.
-The negatively and positively charged ions are attracted to nechother base on their opposite charge.

Question 4

What is electrostatic attraction?

Answer 4

-holds positive and negative ions together - very strong.
When atoms are held tg in a lattice its called ionic bonding.

Question 5

What is a crystal pattern

Answer 5

every ion is attracted to all other ions with the opposite charge.

Question 6

High melting point?

Answer 6

Many strng forces of attraction between +ve and -ve ions making it hard to break.

Question 7

conductivity

Answer 7

when dissolved. in water, molten, ionic compounds conduct electricity

In a GIL there are no delocalised electrons and ions are solid so cant conduct electricity.
