Sructure and Bonding of Group 1 Metals and Group 7 Non Metals

Question 1

Three States of Matter:

Answer 1

• Solid, Liquids and Gases.

Question 2

Solids Features;

Answer 2

• Hard to compress~ Particles are packed together in a regular pattern no spaces in between the particles.
  2) Fixed shape
  3) Cannot flow.
  4) Particles vibrate in a singular spot.
  -

Question 3

Liquid Features:

Answer 3

• Hard to compress~ Particles are close together with not much space.
• Takes the shape of the container + flow.
• ## Particles can move.

Question 4

Features of a Gas:

Answer 4

• Can be compressed easily.
• particles are widely spread.;
• ## Gases spread out and fill the space of the container= move quickly and randomly.

Question 5

How can we change the state of a substance?

Answer 5

• Taking out or putting in energy.

-

Question 6

Solid –> Liquid:

Answer 6

• Melting.
• Liquid Particles have more kinetic energy than solids.
• Put energy in to convert solid to a liquid.
• Energy is needed to break the forces of attractions between the particles of the solid and .
• Once forces are broken= particles can move around.

Question 7

The stronger the forces of attraction between the particles…

Answer 7

the more energy we need to put in to break them and the higher the melting point.

Question 8

Liquid –> Solid:

Answer 8

• Freezing.

- Same temperature as melting point.

Question 9

Liquid —> Gas.

Answer 9

• Boiling - Takes place at boiling point.
• Stronger the forces of attraction- the higher the boiling point.
• ## Takes a lot of energy to break these forces and boil the liquid.

Question 10

Limitations of the Particle Model:

Answer 10

• Assumes that all particles are solid spheres.
• Particles have a lot of different shapes and they are not solid.
• Assumed that there are no forces between the particles.
• ## The forces between the particles have a major impact on the boiling and melting point of a substance.

Question 11

What is ionic bonding?

Answer 11

• Elements react in order to achieve a full outer shell.
• They achieve the electronic structure of a noble gas.
• Metal Reacts with a non metal= ionic bonding.

Question 12

What happens to group 1 metals in ionic bonding?

Answer 12

• Loose an electron.
• ## Forms a positive ion.

Question 13

What happens to Group 7 non metals when they go through ionic bonding?

Answer 13

• Gain 1 electron forming a negative ion;

-

Question 14

What happens to both ions?

Answer 14

• Both have full outer shells.
• ## Like Noble Gases.
