Represnting Ionic Bonds

Question 1

How can ionic bonds be represented

Answer 1

Dot and cross diagrams

Question 2

How should electrons from each atom be represented

Answer 2

Solid dots and crosses, more than two atoms hollow circles or symbol

Question 3

What should dot and cross diagram include ?

Answer 3

Charge on right side outside of brackets

Question 4

Sodium chloride

Answer 4

Sodium Group 1
Looses one electron to get full outer shell
Chlorine
Group 7 non metals, so gains electron
Held together by electrostatic forces

Question 5

Find formula dot and cross

Answer 5

Count # of atoms of each element

Question 6

Find formula 3D lattice structure

Answer 6

3D lattice structure, then look for how many ions are in the lattice

Question 7

How to describe ionic bonding

Answer 7

-how many electrons the metal loses
- the resulting charge of the metal ion
- how many electrons the non-metal gains
-the resulting charge of the non-metal ion
- that the oppositely charged ions are held together by strong forces of attraction in ionic bonding
