There are 6 2p electrons in argon.
Argon is used in light bulbs and many sources of light
Argon atoms have 18 protons which is similar to the number of electrons.
18
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Argon does not normally form ions.
Argon, being a noble gas normally does not form ions.
No. However, ions of argonium (argon hydride) have been identified in space.
No. Argon does not form ions. CH4 is the simplest alkane and is called methane.
Neither. It does not form ions.
there outermost shells are completely filled.
Argon is usually electrically neutral and has no charge. It is possible to ionize it, however (at very high temperatures or by means of a high voltage) at which point it would have a positive charge.
Atoms become ions by gaining or losing electrons to achieve a noble gas configuration of electrons, which is stable. Argon already has such a configuration and is very stable as it is. Any gain or loss of electrons would make it less stable.
Cl & K ions are isoelectronic with Ar.
Argon has 18 electrons.
Argon is generally considered to be unreactive element, i.e. it cannot form compounds. But new researchs have found that argon can form a compound called Argon fluorohydride(HArF) which is very unstable. Here Argon's charge may be neutral, i.e. 0
Argon has 18 electrons.
