Ionic bonding

Question 1

What is a compound?

Answer 1

when two or more elements react and combine chemically

Question 2

Name three types of chemical bonding

Answer 2

Ionic, Covalent and metallic

Question 3

How are positively charged ions formed
also know as ionic bonding

Answer 3

When an electron from the metal’s outer energy level moves to the non-metal’s outer energy layer

Question 4

How are negatively charged ions formed

Answer 4

when a non metal atom gains 1 or more electron from ionic bonding

Question 5

What are particles like in ionic bonding

Answer 5

Oppositely charged, forming ions

Question 6

Where does ionic bonding occur?

Answer 6

In compounds with a metal and non metal

Question 7

What happens when a magnesium atom reacts with a chlorine atom to form magnesium chloride?

Answer 7

One electron transfers from Magnesium to the Chlorine atom to form a full outer shell. However, since the magnesium atom loses 2 electrons and chlorine only needs to gain 1, 2 chlorine atoms are needed to form ions of Mg2+ and Cl1-. (and an ionic compound of MgCl2)

Question 8

Describe ionic bonding

Answer 8

A chemical bond which is formed between strong electrostatic forces between oppositely charged ions

Question 9

Describe the structure of an ionic compound

Answer 9

Giant, ionic, lattice structure with strong electrostatic forces between oppositely charged ions

Question 10

REMEMBER HOW TO DO A DOT AND CROSS DIAGRAM FOR IONIC BONDING

Answer 10

REMEMBER HOW TO DO A DOT AND CROSS DIAGRAM FOR IONIC BONDING

Question 11

Why do ionic compounds have high melting and boiling points?

Answer 11

strong electrostatic forces between oppositely charged ions which require high amounts of energy to break

Question 12

Why can ionic compounds conduct electricity in liquid state?

Answer 12

the ions can move freely which allows the charge to flow

Question 13

What are the disadvantages of using a dot and cross diagram

Answer 13

It doesn’t show that ionic compounds are giant structures made from many compounds

Question 14

advantages of a dot and cross diagram

Answer 14

shows the symbol of ions and how electrons are transferred.

Question 15

advantages of a 2D diagram

Answer 15

shows a regular repeating pattern

Question 16

disadvantages of a 2D diagram

Answer 16

Doesn’t show electron transfer. Implies that ionic compounds are 2D, but they are 3D

Question 17

advantages of 3D diagram

Answer 17

shows a 3D, regular repeating pattern

Question 18

disadvantages of a 3D diagram

Answer 18

doesn’t show electron transfer, implies there are no ions inside the structure

Question 19

advantages of ball and stick

Answer 19

shows a 3D regular repeating pattern

Question 20

disadvantages of a ball and stick diagram

Answer 20

does not show electron transfer. Implies there are gaps between ions, which are not there

Question 21

Why do ionic compounds have high boiling and melting points

Answer 21

there are many strong electrostatic forces between oppositely charged ions which require large amounts of energy to overcome

Question 22

Why can ionic compounds conduct electricity in a liquid state

Answer 22

ions are free to move around, so it can conduct electricity as charge can flow
