[2016] Naomichi Kumagai (PYP 4O): Hydrogen

Negitive thingsIn North Korea Kim Jong -un made a very powerful wepon called hydrogen bomb.

How humans have chaged hydrogenHydrogen is also used in a process called hydronation. This process changes vegtable oils to solid fats.

HYDROGENSymbol:H Atomic weight: 1.00794 Density:0.0000899

Where is hydrogen inside?Hydrogen is in all plants. There are sugars all throughout plants and there is hydrogen in sugar. That's why animals eat plants... For the sugar and the energy.

What is hydrogen?Hydrogen is natural meterialHydrogen comes first inthe periodic table. Hydrogen is the simplest chemical element. H2O is two hydrogen and one oxygen. Hydrogen is in H2O stands for water and hydrogen is all around the atmosphere. Hydrogen is the lightest of all the gases. Hydrogen can be as liquid under high pressure and an extremely low temperature of (-252.87C). Hydrogen is often stored in as liquid.Liquid hydrogen takes up less space than hydrogen in it normal gas form Liquid hydrogen is also used as a rocket fuel.

Atomic number 1

What is hydrogen used for?Hydrogen is used in something called cryogenics. Cryogenics is a process when scientists freeze things. When hydrogen is in a liquid form it is very, very cold. Scientists use this cold hydrogen to freeze things very quickly.

Positive thingsHydrogen is natural meterialHydrogen comes first inthe periodic table. Hydrogen is the simplest chemical element. Cryogenics is a process when scientists freeze things very quickly. We wouldn't have rocket.
