Key Stage 2

Meaning

Hydrogen is a gas that can catch fire easily.

Key Stage 3

The chemical symbol for Hydrogen.
A 2 dimensional representation of a Hydrogen atom with 1 proton in the nucleus and 1 electron orbiting the nucleus.

Meaning

Hydrogen is a non-metal element with 1 proton in the nucleus.

About Hydrogen

Molecular Structure

Hydrogen has the chemical formula H2.
Two Hydrogen atoms join together to form a Hydrogen molecule.

Atomic Structure

Hydrogen has 1 proton and 0 neutrons so it has an atomic mass of 1.
An atom of hydrogen has one electron.
A Hydrogen ion has usually lost its only electron to become positively charged.

Properties

Hydrogen is a gas at room temperature.
Hydrogen gas is less dense than air.
Hydrogen reacts with Oxygen to form water.

Testing for Hydrogen

  1. Collect the gas in a test tube.
  2. Place a lit splint over the mouth of the test tube.
  3. If a 'squeaky pop' sound is made then the gas is Hydrogen.

Key Stage 4

The chemical symbol for Hydrogen.
A 2 dimensional representation of the Bohr Model of a Hydrogen-1 isotope with 1 proton in the nucleus and 1 electron in its outer shell.

Meaning

Hydrogen is a non-metal element with 1 proton in the nucleus.

About Hydrogen

Molecular Structure

Hydrogen has the chemical formula H2.
Two Hydrogen atoms join together in a covalent bond.
HydrogenDotandCrossDiagram.png
A dot and cross diagram of a Hydrogen molecule.

Atomic Structure

The most common isotope of Hydrogen has 1 proton and 0 neutrons so it has an atomic mass of 1.
Hydrogen Deuterium Tritium

Hydrogen always has 1 proton but isotope there are no neutrons. Hydrogen always has 1 proton but in this isotope there is 1 neutron. This isotope of Hydrogen is known as Deuterium. Hydrogen always has 1 proton but in this isotope there is 2 neutrons. This isotope of Hydrogen is known as Tritium.
An atom of hydrogen has one electron.
A Hydrogen ion has usually lost its only electron to become positively charged.

Properties

Hydrogen is a gas at standard temperature and pressure.
Hydrogen gas is less dense than air.
Hydrogen reacts with Oxygen to form water.

Testing for Hydrogen

  1. Collect the gas in a test tube.
  2. Place a lit splint over the mouth of the test tube.
  3. If a 'squeaky pop' sound is made then the gas is Hydrogen.
