C8H12
8 Carbon atoms + 12 Hydrogen atoms = 20 atoms total
23 g of sodium metal will have 6.023 x 1023 atoms (or 1 mole of atoms)
There are 3 carbon atoms in a molecule of C3, as indicated by the subscript "3" following the element symbol C.
same number of each element
A substance in which all atoms are identical is called an element.
The smallest particle of an element that maintains the characteristics of the element is an atom. Each element is composed of unique atoms with specific properties determined by its atomic structure.
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 number of atoms in an element depends on the element's atomic mass and the amount of the element present. One mole of an element contains approximately 6.022 x 10^23 atoms, known as Avogadro's number.

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.
Some elements have isotopes - atoms with a different number of neutrons.
Copper is an element. You can have a single atom or many atoms and it's still copper.
