One million argon atoms are how many moles of argon atoms?
1.7x10^-18
The actual mass of an atom of argon is is 6.63x10-24g How many atoms are in a 40.0-g sample of argon?
Divide 40g by the mass of one atom to find the number of argon atoms.
How many atoms in a molecule of argon?
There is one atom in argon. Argon is a "noble gas", which means that it occurs independently. This is true for all of the atoms on the final column of the periodic table. http://en.wikipedia.org/wiki/Noble_gas
How many atoms of argon are in one mole?
The number is Avogadro's number, 6.0221409 *10^23
How do you calculate the volume one atom of argon?
If the calculated radius of argon is 71 pm the volume of an atom is 630347 (pm)2.

Is Ar a atom or molecule?
Argon (Ar) is an atom not a molecule. An atom is singular whereas a molecule is a group of two or more atoms.
How many protons are in the nucleus of Ar atoms?
It depends on the identity of the atom. For example, Hydrogen has one proton, but Helium has two.
How many particles are in 23.9 g Argon?
7.996*1023 Let's see if I can remember how to do this. I think the atomic mass of Argon is about 39.9 approx, so 1 mole of Argon weighs 39.9grammes. Avogadro's number tells us how many atoms are in 1 mole of any element. The value is about 6.0221415 x 10^23. So in 39.9grammes we have 6.0221415 x 10^23 atoms (because as far as I remember Argon is a monatomic gas - i.e. unlike for example Oxygen which hangs around in pairs of Oxygen atoms O2) Anyway, number of atoms/particles in 23.9g of Argon would be about (23.9/39.9) x 6.0221415 x 10^23 = 3.607 x 10^23 particles. That looks about right........................... Unless of course you meant to include sub-atomic particles................ That's too hard. Who asked this anyway?
How many nutrons does argon have?
There are 3 Isotopes with the following mass numbers: Argon 36 Argon 38 Argon 40 Argon has an atomic number of 18 (it therefore has 18 protons in its nucleus and 18 electrons flying round it). To get the number of neutrons one subtracts the atomic number from the mass number. This means that some Argon atoms have 18 neutrons, some 20 neutrons and some 22 neutrons the isotope with 22 neutrons is the most common and forms 99.6% of all Argon.
How many electrons are in energy level 3 of argon?
it has eight electrons in its outermost shell, which is one of the qualifications of the first three noble gases. The highest energy level refers to the atoms outer shell of electrons
Why do atoms combine with another atoms?
Atoms combine with other atoms to become more stable. For example, Na (Sodium) has 11 atoms and if it gives Cl (Chlorine) one atom, it will then become 18 atoms. Ar (Argon) has 18 atoms which is also equivalent. When Sodium loses one it will then become 10 atoms, which is also equivalent to Ne (Neon). It is sort of a win-win situation.
What group of elements does argon belong to?
Helium, Neon, Krypton, Xenon, and Radon
