This depends on the mass of this element.
Zero. Oxygen is an element.
The chemical formula shows you this. The subscripted number next to each element shows how many atoms are present in a molecule or formula unit. If no number is shown, then only one atom of that element is present.
You can determine the number of atoms of each element in a compound by using the chemical formula of the compound. The subscripts in the formula indicate the number of atoms of each element. For example, in H2O (water), there are 2 hydrogen atoms and 1 oxygen atom.
The atomic number of an element tells you how many protons an atom of that element contains. This number is unique to each element and is found on the periodic table. The number of protons in an atom determines the element's identity.
The element phosphorus has 15 atoms, as indicated by its atomic number on the periodic table.
There are no "atoms in an element," but rather atoms OF an element. If you are trying to find the number of atoms in a sample of a pure element you divide its weight by its molar mass and then multiply by 6.022 x 10^23 to get the answer in atoms. The answer options are 2,3, or 4.
Gold is the element gold no matter how many atoms of it you have.
Rutherfordium is a single chemical element.

Zero. Oxygen is an element.
2 moles of ANY element contains 2x6.02x10^23 atoms of that element = 1.2x10^24 atoms.
The chemical formula shows you this. The subscripted number next to each element shows how many atoms are present in a molecule or formula unit. If no number is shown, then only one atom of that element is present.
CuSO4 isn't an element.
Copper is an element. You can have a single atom or many atoms and it's still copper.
Some elements have isotopes - atoms with a different number of neutrons.
C8H12 8 Carbon atoms + 12 Hydrogen atoms = 20 atoms total
