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
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.
