Sodium is an element- you just need one atom. Its a trick question
23 g of sodium metal will have 6.023 x 1023 atoms (or 1 mole of atoms)
In one molecule of NaCl there are two ions, Na+ and Cl-.
There are no sodium atoms in a hydrogen atom. Sodium and hydrogen are different elements with distinct chemical properties and atomic structures. Sodium has 11 protons in its nucleus, while hydrogen has 1 proton in its nucleus.
CuSO4 isn't an element.
There are: 12 sodium atoms (4 x 3) 1 phosphorus atom 4 oxygen atoms
one atom
0,2 mol sodium contain 1,204.10e23 atoms.
Sodium oxide is made up of three atoms: two sodium atoms and one oxygen atom.
A mole is a counting unit of molecules. Since sodium is an element and is exists by itself one mole of sodium will equal one mole of atoms or 6.02 x 1023 atoms.
Borax has two sodium atoms.
In the formula Na2SO4, there are 2 sodium (Na) atoms, 1 sulfur (S) atom, and 4 oxygen (O) atoms.
The number of sodium atoms in a compound depends on the formula of the compound. For example, in NaCl (sodium chloride), there is one sodium atom because the formula consists of one sodium atom and one chlorine atom. In Na2CO3 (sodium carbonate), there are two sodium atoms because the formula contains two sodium atoms.
