The Periodic Table

Question 1

What is group 1 elements called?

Answer 1

Alkali metals

Question 2

How many electrons do group 1 metals have?

Answer 2

1 electron

Question 3

What are some of the properties of group 1 metals?

Answer 3

They are all very reactive, they all have metallic structures.

Question 4

What happens when you go down the group for group 1 and why?

Answer 4

Reactivity increases as you go down the group becuase the outer electron is further from the nucleus and easier to loose.

Question 5

All group 1 metals burn in oxygen to form ______.

Answer 5

metal oxides.

Question 6

All group 1 metals react with chlorine to form ________.

Answer 6

metal chlorides

Question 7

Answer 7

Lithium hydroxide

Hydrogen gas

Question 8

Lithium + oxygen > what?

What is this in symbol equation (balanced)?

Answer 8

lithium oxide

4Li + O2 > 2Li2O

Question 9

Lithium + chlorine > what?

What is this in symbol equation (balanced)?

Answer 9

Lithium chloride

2Li + Cl2 > 2LiCl

Question 10

Lithium + water > what?

What is this in symbol equation (balanced)?

Answer 10

Lithium Hydroxide + Hydrogen

2Li + 2H2O > 2LiOH + H2

Question 11

What is the melting/boiling point of a metal compared to a non-metal?

Answer 11

Metal: High

Non-Metal: Low

Question 12

What is the density of a metal compared to a non-metal?

Answer 12

Metal: High

Non-Metal: Low

Question 13

What is the malleability of a metal compared to a non-metal?

Answer 13

Metal: High

Non-Metal: Low (brittle)

Question 14

What is the conductivity of a metal compared to a non-metal?

Answer 14

Metal: Yes

Non-Metal: No

Question 15

Are the ions positive or negative in a metal compared to a non-metal?

Answer 15

Metal: Positive

Non-Metal: Negative

Question 16

Why are Transitional Metals commonly used as catalysts in industry?

Answer 16

Because they can form ions with different charges.

Question 17

What are Group 0 elements called?

Answer 17

Group 0 elements are called Noble Gases

Question 18

How many electrons do Group 0 elements have and why is this important?

Answer 18

Group 0 elements have a full outer shell (usually 8 but Helium has 2). This is important as they are not reactive. This means they are also therefore monoatomic.

Question 19

Group 0 elements are mono___

Answer 19

Monoatomic

Question 20

What happens to the boiling point as you go down the group (Group 0)

Answer 20

Boiling point increases down the group as the number of electron shells increases.

Question 21

What are group 7 elements called?

Answer 21

Group 7 elements are called Halogens

Question 22

What type of molecules do group 7 elements form?

Answer 22

Diatomic molecules (Cl2, Br2)

Question 23

What happens to the melting point as you go down the group (group 7)?

Answer 23

Melting point increases.

Question 24

What happens to the reactivity as you go down the group (7)?

Answer 24

Reactivity decreases down the group because the outer electrons are further from the nucleus and it gets harder to attract an extra electron.

Question 25

What happens when they (halogens) react with non metals?

Answer 25

They form a covalent molecule.

Question 26

How does displacement work for Halogens?

Answer 26

A less reactive halogen will get displaced from a halide compound by a more reactive halogen. (Higher up is more reactive)

Question 27

Metal + Non-Metal = ?

Answer 27

Ionic compound

Question 28

Non-metal + Non-metal = ?

Answer 28

Covalent compound

Question 29

Metal + Metal = ?

Answer 29

No reaction
