Ionic bonding

Question 1

What happens when metals and non-metals react together ?

Answer 1

The metal atoms lose electrons to positively charged ions

Question 2

What happens to the non-metals during this process?

Answer 2

The non metals gain the electrons to form negatively charged ions

Question 3

What happens to the oppositely charged ions ?

Answer 3

The become strongly attracted by an electrostatic force, which is called an ionic bond

Question 4

What do dot and cross diagrams show ?

Answer 4

They show how electrons are arranged in an atom or an ion and it shows which atom the electrons in an ion came from

Question 5

What happens to sodium chloride during this process ?

Answer 5

Sodium loses an outer shell electron, and forms an NA + ion. Chlorine gains the electron which forms a CL- ion

Question 6

What happens with magnesium oxide ?

Answer 6

Magnesium loses two outer shell electrons and forms and MG2+ ion, The oxygen atom gains these electrons forming a 02- ion

Question 7

What happens to magnesium chloride within this process ?

Answer 7

The magnesium loses to outer shell electrons and forms an MG2+ ion and the two chlorine atoms gain an electron each which forms two Cl- ions
