Bonding, Structure, And Properties Of Matter

Question 1

Explain Magnesium and Oxygen reacting to each other (5 points)

Answer 1

-transfer of electrons from Magnesium to Oxygen
-magnesium loses 2 electrons, oxygen gains 2 electrons
-the ratio is 1 magnesium to 1 oxygen
-magnesium is a positively charged ion and oxygen is a negatively charged ion

Question 2

What is a positively charged ion?

Answer 2

Cation

Question 3

What is a negatively charged ion called?

Answer 3

Anions

Question 4

What kind of structure do ionic compounds have?

Answer 4

Giant ionic lattice structure

Question 5

What forces are in ionic compounds between oppositely charged ions?

Answer 5

Electrostatic forces of attraction

Question 6

What are 2 properties of Ionic compounds?

Answer 6

1- can’t conduct electricity when solid
When melts, ions are free to move, carry electric charge
When dissolved in water, ions separate, free to move, electric charge

2- high boiling and melting points, many strong bonds between ions, need lots of energy to overcome forces of attraction
