the atomic number for argon is 18.
The number of neutrons in an argon atom is 22. This is calculated by subtracting the atomic number of argon (18) from its atomic mass number (40).
Not sure about portons but americium has 95 protons.
Argon is a gas element. atomic number of it is 18.
The atomic number of argon is 18.
12
No. Sulfur has an atomic number of 16 and Argon has an atomic number of 18
It is the mass number, i.e., the total number of protons and neutrons in argon and is ofter used to calculate the number of neutrons present. As the atomic number (or the number of protons) for argon is 18, there will be 22 neutrons in Argon-40 isotope.
