The first step is to identify what you have and what you need. The units of our data is grams. The units that we desire is number of atoms. Therefor, to answer this question, we need two important tools of chemistry: the Periodic Table, where we can find the molar mass of the element (bottom of the element's box), and Avogadro's number, which is the number of atoms in one mole.
Going to our periodic table, we find the molar mass to be
M=20.1797 grams/mole
and Avogadro's number is
NA=6.022*1023 atoms/mole
To make the conversion, we simply track our units through the calculation:
80 grams of Ne * 1 mole Ne/20.1797 grams Ne * 6.022*1023 atoms Ne/mole Ne=
2.39*1024 atoms Ne
It is worth noting that any conversion factor can be reversed by reciprocating the value. In the above example, the molecular mass is given in grams per mole, which can be used to convert moles to grams. The reciprocal was used to convert grams into moles.

How do helium argon and neon differ?
Helium, argon, and neon are noble gases with different atomic numbers: helium (2), neon (10), and argon (18). They vary in terms of their densities, boiling points, and chemical reactivity. Neon has the lowest boiling point and argon has the highest atomic weight among the three.
What are neon atoms?
Neon atoms are the atoms of the inert, colorless, and odorless gas neon. Neon freezes at -248.59°C, boils at -246.08°C, and has a specific gravity of 0.8999 at 0°C. Neon atoms have 10 electrons, 10 protons, and 10 neutrons. When excited by an electric current, neon glows red and is widely used in advertising signs. It is also used as a refrigerant in cryogenics.
Which subatomic particle identifies an atom of a particular element?
It's the count of one of the subatomic particles in the nucleus, the proton, that is significant in this regard. For example, an atom is hydrogen if and only if it has one proton in its nucleus. It is neon if and only if it has ten protons in its nucleus.
What element has 24 protons and 21 electrons?
An element's number of protons is the same as its atomic number. Thus, an atom with 21 protons has the atomic number 21. By looking up this element on the periodic table, one finds that it is scandium.
What does an isolated atom have as a net charge?
This is an oddly stated question but I would assume you are talking about elements such as neon, argon, xenon, krypton, i.e. noble gases which are monoatomic elements. They are inert gases that, under ordinary circumstances, do not react with other elements to form compounds.
How many atoms are contained in 2 moles of neon?
Two moles of neon contain 12,044281714.10e23 atoms.
How many protons does have neon contain?
Neon's atomic # is 10 so it has 10 protons
How many protons does neon-12 have?
Neon has 10 protons; the isotope Ne-12 doesn't exist.
How many protons are in the necleus of neon?
10
How many electrons are there in a neon atom with ten protons?

How many protons does the element neon have?
10 Protons 10 Neutrons in the most common isotope.
How many moles are in 0.125 L of Ne?
0,125 L neon is equivalent to 0,0056 moles.
How many protons and neutrons are in the element?
Neon has 10 protons and 9 neutrons.
How do you find the number of protons in a neon atom?
The number of protons is equal to atomic number: neon 10 has protons.

Ten protons, ten electrons and 8 neutrons are there in Ne-18.
How many protons are found in the nucleus of neon?
10
