Key Stage 2

Meaning

Argon is a gas.

Key Stage 3

The chemical symbol for Argon. A 2 dimensional representation of a Argon atom with 18 protons and 22 neutrons in the nucleus and 18 electrons orbiting the nucleus.

Meaning

Argon is a Group 0 element, on the Periodic Table, with an atomic number of 18.

About Argon

Argon has the chemical formula Ar. Argon has 18 protons and 22 neutrons in its nucleus giving it an Atomic Number of 18 and an atomic mass of 40. Argon is a Noble Gas. Argon is a gas at room temperature. An atom of Argon has a full outer shell of 8 electrons so it is inert.

Key Stage 4

The chemical symbol for Argon. A 2 dimensional representation of the Bohr Model of a Argon-40 isotope with 18 protons and 22 neutrons in the nucleus and 2 electrons in the first shell, 8 in the second and 8 in the outer shell.

Meaning

Argon is a Group 0 element, on the Periodic Table, with 18 protons in the nucleus.

About Argon

Argon has the chemical formula Ar. The most stable isotope of Argon has 22 neutrons in its nucleus giving it an atomic mass of 40. Argon is a Noble Gas. Argon is a gas at standard temperature and pressure. An atom of Argon has a full outer shell of 8 electrons so it is inert.
