18 when neutrally charged.
18 protons, 22 neutrons and 18 electrons. See the Periodic Table of elements, e.g. in: http://en.wikipedia.org/wiki/Periodic_table#Methods_for_displaying_the_periodic_table
There are 18 electrons and protons each in argon atoms.
Argon has 18 electrons and protons...Neutrons is 22
Protons = 18neutrons = 22 (for the most stable isotope of argon, Ar-40)
i will say 18 neutrons and electrons
There are 18 protons in each atom.
There are 18 electrons and protons each in argon atoms.
There are 18 electrons and protons each in argon atoms.
Argon atoms have 18 protons which is similar to the number of electrons.
Argon has 18 electrons and protons...Neutrons is 22
Protons = 18neutrons = 22 (for the most stable isotope of argon, Ar-40)
there are 18 in an ARGON.
18 protons and 20 neutrons
i will say 18 neutrons and electrons
18 protons and 18, 20 or 22 neutrons.
18 protons and 22 neutrons in the most commonly occurring isotope argon-40. In argon-36 there are 18 neutrons but this isotope is only present in nature at 0.34%
Argon has 18 protons
Argon 38 has eighteen protons and twenty neutrons. Argon 36 has eighteen protons and eighteen neutrons.
