The element with atomic number 18 is Argon. It is a noble gas with the symbol Ar.
Argon is a gas element. atomic number of it is 18.
Argon is a non meta element. Atomic number of it is 18.
The element with 18 protons is argon (Ar), with atomic number 18. Its mass number is calculated by adding the protons and neutrons, so 18 protons + 20 neutrons = mass number 38 for this particular isotope of argon.
The element argon has 22 neutrons. It has 18 protons and 18 electrons, giving it an atomic number of 18. The number of neutrons is calculated by subtracting the atomic number from the atomic mass, which is 40 for argon (obtained by rounding the atomic weight to the nearest whole number).
Atomic number = Number of protons = 35 - 18 = 17.So the element is chlorine.
