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.

∙ 9y agoThere are 10 protons per atom of neon. In 20.02 moles of neon there are 1.206 E25 atoms. This is determined by using Avogadro's number. So, there are 1.206 E26 protons in 20.02 moles of neon.

How do helium argon and neon differ?
They differ in the number of protons in their nucleus.
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 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.
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.
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 elcetrons protons neutrons does the element neon have?
neon has ten of each.
How many electrons are there in a neon atom with ten protons?
Neon has 10 electrons.
How many protons and neutrons are in the element?
Neon has 10 protons and 9 neutrons.
How many moles are in 0.125 L of Ne?
0,125 L neon is equivalent to 0,0056 moles.
How many electrons does the element neon?
The Element Neon has 10 protons and 10 electrons.
How many protons are found in the nucleus of neon?
10
How many electrons neutrons and protons are in an atom of neon?
Protons: 10 Neutrons: 10
How many protons electrons and valence elecrons does neon have?
Neon's atomic number is 10. Thus, neutral neon has 10 protons and 10 electrons. Since neon is a noble gas, it has 8 valence electrons.
