Question 1

What happens when alkali metals react with water?

Answer 1

The metal creates alkali as it reacts water (purple with universal indicator)
The metal with water creates hydrogen
The metal floats, moves and fizzes.

Question 2

What happens when alkali metals react with sodium?

Answer 2

In addition this moves quicker and has a ball shape

Question 3

What happens when alkali metals react with potassium?

Answer 3

In addition it moves quickly and has a lilac flame.

Question 4

What are the properties of alkali metals and what group are they in?

Answer 4

GROUP 1
1 electron on the outer shell
All metals look DULL on the outside
Over a short period of time a LAYER of oxide makes the metal LOOKS DULL.
The INSIDE of every metal is SHINY
It is possible to CUT every metal with a KNIFE
They are kept in OIL to prevent them from reacting with oxygen and moisture in the AIR
Their DENSITY is low therefore most FLOAT
The BOILING point and MELTING point are LOWER than many other metals

Question 5

What do halogens react with?

Answer 5

Group 1 metals and salts

Question 6

How many ______ does a halogen have on the outer shell?

Answer 6

7 electrons

Question 7

What colour and types are these group 1 elements:

Chlorine
Bromine
Iodine

Answer 7

Chlorine - yellow green gas
Bromine - orange red liquid
Iodine - shiny grey solid

Question 8

State properties of halogens

Answer 8

They create white solids

The halogens become less reactive down the group

Question 9

Name the results of the flame test for these three halogen metals:

Lithium
Sodium
Potassium

Answer 9

Lithium - red
Sodium - yellow/orange
Potassium - lilac

Question 10

What is the results of the silver nitrate test with these three non metals in group 1?

Chloride
Bromide
Iodine

Answer 10

Chloride - white
Bromide - cream
Iodide - yellow

Question 11

How reactive do group 1 metals become as they go down the group?

Answer 11

Group 1 metals become more reactive down the group

Question 12

How reactive does halogens get as you go down the group?

Answer 12

Group 7 non-metals become less reactive down the group

Question 13

How do group 1 metals react?

Answer 13

They lose 1 electron

Question 14

How does group 7 non metals react?

Answer 14

By gaining 1 electron

Question 15

What is an atomic structure?

Answer 15

Atoms contain a nucleus and electrons
The small central nucleus is made of protons and neutrons
Around these are orbits of electrons

Question 16

What is different with different elements?

Answer 16

The number of protons

Question 17

What is the same for some elements?

Answer 17

Neutrons

Question 18

What is the same when atoms have bonded?

Answer 18

Electron number

Question 19

What are the physical properties of metals?

Answer 19

Conduct electricity
Conduct heat
High melting & boiling point 
Malleable 
Ductile

Question 20

What is the physical properties of non metals?

Answer 20

Does not conduct electricity
Does not conduct heat
Low melting/boiling point
Not malleable 
Not ductile

Question 21

What does atoms have?

Answer 21

No charge

Question 22

What charge does the following have?:

Protons
Electrons
Neutrons

Answer 22

Protons - positively charged (+)
Electrons - negatively charged (-)
Neutrons - do not have a charge (0)

Question 23

What does an ion have?

Answer 23

An uneven number of protons and electrons
This happens when an electron is lost
Or when an electron is gained
The proton number does not change

Question 24

What is the atomic number in this element?

7
Li
3

Answer 24

3

The number in the bottom which means the number of protons or electrons
The number increases across the periodic table

Question 25

What is the mass number in this element?

7
Li
3

Answer 25

7

Number on the top which means the number of protons and neutrons in the nucleus

Question 26

What is the neutron number?

Answer 26

The number of neutrons in and atom is worked out by subtracting the number of protons (atomic number) from the mass number

Question 27

What happens when an alkali metal reacts with oxygen and water?

Answer 27

Oxygen causes the surface of the metal to turn dull by forming a layer of oxide.

The oxide layer forms quicker as we go down the group
