Flashcards in Chapter 3- Ionic Bonding Deck (29):
1

What subtances are apart of ionic compounds?

Metals and non-metals are joined by ionic bonds

2

Which elements to ions want to be like?

The noble gases

3

What do all atoms want?

Stability

4

What atoms are free atoms?

The Nobel Gases

5

What makes an atom stable?

Having a full valance shell with electrons

6

What are the ways in which atoms can become stable?

-By sharing electrons
-By gaining or loosing electrons

7

What are the three types of chemical bonds?

Ionic
Covalent
Metallaic

8

What happens when atoms loose electrons

An atom that has lost electrons has an overall positive charge and is called a cation

9

What happens when an atom gains electrons

An atom that has gained electrons has an overall negative charge and is called an anion

10

What is another name for an ionic compound?

Salt

11

What produces the ionic bond?

An ionic bond is produced when atoms are oppositely charged and there attraction, which is called electrostatic attraction produces an ionic bond.

12

What shape are ionic compunds in?

Network lattices with each cation surrounded by an anion and each anion surrounded by a cation

13

What are some properties of ionic substances?

-Hard
-Brittle
-Solid at room temperature

14

What dimension are ionic substances?

Three Dimensional

15

What are ionic lattices held together with?

Electrstatic attraction

16

What is an empirical formula?

A ratio given to each ionic compound

17

Why are ionic compounds crystals?

Due to the repeating arrangement of ions.

18

What is the boiling point like for ionic compounds?

Have a high/melting/boiling point making it harder to seperate the ions.

19

Do ionic compounds conduct electricity in the solid form?

No

20

What substance can ionic compounds conduct electricity in?

Aqueous solutions

21

What do ionic compounds do when placed in water?

They dissolve in water to form ions this is due to the water molecules being able to move between the ions.

22

What happens when an ionic compound is placed in a molten solution?

Ions are able to conduct electricty due to the ions being able to slide past one another

23

Define an electrolyte

Ions that are free to move, they can either by a molten ionic compound or an aqueous solution of an ionic compound.

24

Define Binary Ionic compound.

When only two elements are present in a compound

25

Put in order the strongest to weakest types on intramolecular bonding?

1.Covalent
2.Ionic
3.Metalliac

26

Does an ionic compound have a high or low melting point?

High

27

What are the physical properties assoscaited with the bonding model of ionic substances

-Form three dimensional crystalline lattices also known as salts. With alternating anions and cations
-Have high melting points as a large amount of energy is needed to seperate the ions
-Do not conduct electricity in the solid form as charged particles are not allowed to move
-Dissolve in water, water molecules can move inbetween ions

28

In the molten form why is it that ionic compounds can conduct electricity?

Ions are able to slide past one another

29

Why are ionic lattices brittle?

Pressure causes charges to align resulting in shattering
