Alkali Metals

Elements

• Lithium
• Sodium
• Potassium
• Cesium
• Francium

ALKALI METALS

• A distinguishing quality of Alkali Metals are that they have one electron in the furthest energy level in the structure of an atom
• Alkali Metals are known for the way it reacts to other items (ex. If you throw water on it the Hydrogen becomes a gas and leaves the metals
• Alkali Metals are so reactive that if you were to add them with Potassium you could create an explosion

Real World Connection

• Alkali Metals are a main component of Salt Chloride (Salt)
• The Salt that Alkali Metals can create will help in someone getting necessary amounts of sodium
• Lithum is
• Potassium and Chlorine are often times used to be another way of getting salt, potassium is need in our bodies daily life

Hydrogen

Physical Properties

• Colorless
• Extremely Flammable
• Cannot taste it or smell it
• Textureless

Atomic Information

• Atomic number: 1
• Atomic mass: 1.007
• Non-metal
• 1.29g/l It would float

Everyday Uses

• The Sun is a giant ball of burning energy, and the Sun keeps because of Hydrogen
• Hydrogen was originally used to fly Blimps, but after a horrible accident they no longer do that
• In recent times Hydrogen is being used to help power vehicles, as we look for a non fossil fuel option

Interesting Facts

• There is hydrogen in very compressed parts of Jupiter
• Hydrogen can also be found in metallic liquid in the crust of Saturn
• One of the gases used in blowtorches is hydrogen

Historical Presence

• In one of the darker days in public transport "The Hindenburg" blew up and 37 people died as the Hydrogen ignited and exploded
• First discovered as a gas in 1766
