-Potassium
-Rubidium
-Cesium
-Francium

Helium:
It has a low boiling point, low density. Helium was the first gas used for filling balloons and dirigibles.

Neon:
Neon is a colourless, with about two-thirds the density of air.

Argon:
It makes up about 1% of the Earth's atmosphere. Argon has approximately the same solubility as oxygen and it is 2.5 times as soluble in water as nitrogen . This element is colourless in both its liquid and gaseous forms.

krypton:
Krypton is a colourless gas. It has a boiling point of -152.9°C (-243.2°F) and a density of 3.64 grams per liter. That makes krypton about 2.8 times as dense as air.

Xenon:
Xenon's Melting point is - 112 °C
and the is Boiling point - 107 °C

Radon:
Radon is colourless at standard temperature and pressure and it is the most dense gas known. At temperature below it's freezing point is has a brilliant yellow colour.

1. This is the only part of the periodic table that has elements in it's gaseous form.
2. Unlike other gases, Helium is collected from underground reservoir of natural gas and is not collected by the distillation of air.
3. The melting and boiling points of the noble gases are very close to each other.
4. These noble gases are mostly found on the Earth's atmosphere than the Earth's crust.
5. Ununoctium (element 118) is probably the next noble gas after Radon, but after 0.89 milliseconds, it decays and turns into Ununhexium (element 116), so it is not considered a noble gas.
6. Noble gases were discovered by Lord Rayleigh and Sir William Ramsay.
7.  Their oxidation number of 0 prevents the noble gases from forming compounds readily.

Helium: Is much lighter than air and is used in balloons and blimps

Neon: Neon is used glow lamps, electron tubes and signs.

Argon: Is particularly important for the metal industry.

Krypton: Is used in some types of photographic flashes used in high speed photography.

Xenon: is used in photographic flashes, in high pressure arc lamps for motion picture projection, and in high pressure arc lamps to produce ultraviolet light.

Radon: Is used to treat cancer and other diseases. However too many radon can be very radioactive and causeses leukemia.

Lithium:
Atomic No. = 3
Density = 0.53 g.cm ⁻³ at 20 °C
Melting point = 180.5 °C
Boiling point = 1342 °C

Sodium:

Atomic No. = 11
Density = 0.97 g.cm -3 at 20 °C

Melting point = 97.5 °C

Boiling point = 883 °C

Potassium:
Atomic No. = 19
Density

Rubidium:

# data[].attributes.body
-Lithium: changes the flow of Sodium in nerve and muscles cells in the body.

-Sodium: Is generally mixed with chlorine to make a compound called Sodium Chloride. Which is known as salt.

-Potassium: Potassium is generally known as a Nutrient which is found in foods in Bananas. It is also mixed in Chlorine which is used to fertilize salt.

-Rubidium: This element is used in vacuum tubes to act as getters. Getters are a material that binds with and removes trace gases from vacuum tubes.

-Cesium: Cesium is used in atomic clocks, photoelectric cells and to act as catalyst in a hydrogenation of a certain organic compounds.

-Francium: It has a half life, of 22 minutes, so currently it doesn't have any uses in everyday lives or any

-only have one valance electron (The electrons on the outermost shell of the atom)
-They are stored in oil due to their reactivity with water.
-They become discoloured and rust if they come in contact with air which is called oxidation.
-Sometimes cesium is also spelled caesium
-Their atomic numbers are odd
-The different alkali metals burn in different colors.
-They make salt when reacting with halogens (for example sodium chloride is common table salt)

Fun Facts

1.They are silvery, shiny, and relatively soft metals.

2.They are fairly reactive under standard conditions.

3.They have two outer valence electrons which they readily lose.

4.They all occur in nature, but are only found in compounds and minerals, not in their elemental forms.

5.They react with halogens to form compounds called halides.

Names of elements:
- Chlorine - Cl - 17
- Bromine - Br - 35
- Iodine - I - 53
- Fluorine - Fl - 9
- Astatine - At - 85
- Tennessine - Ts - 117

Properties of the group:
- Alternative name for group 7 in the periodic table
-  Seven electrons in the outer shell of each element
- Form salt when they react with metals
- Only group in the periodic table with all three states of matter, solid, liquid and gas

Uses of the elements:
Both chlorine and bromine are used as disinfectants for drinking water, swimming pools, fresh wounds, spas, dishes, and surfaces. Chlorine and bromine are also used in bleaching.

Fun Facts:
- Chloride is one of the two elements that make salt
- Fluorine gas is deadly
- Simple compounds that contain halogens are called halides
