one atom
Sodium oxide is made up of three atoms: two sodium atoms and one oxygen atom.
23 g of sodium metal will have 6.023 x 1023 atoms (or 1 mole of 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.
Sodium is an element- you just need one atom. Its a trick question
Borax (Na2B4O7) has two sodium atoms in the formula unit.
One molecule of table salt, or sodium chloride (NaCl), consists of two atoms: one sodium atom and one chlorine atom.
The formula for sodium sulfate is Na2SO4. Therefore, there are 2 sodium atoms, one sulfur atom, and 4 oxygen atoms, for a total of 7.
Common salt is sodium chloride (NaCl) which is composed of two atoms, one of sodium and one of chlorine.
A formula unit of sodium acetate contain two oxygen atoms.
In one molecule of Na2S (sodium sulfide), there are 2 atoms of sodium (Na) and 1 atom of sulfur (S).
To find the number of hydrogen atoms that make up the same mass as one sodium atom, you need to compare the atomic masses. A sodium atom has an atomic mass of 23 daltons, while a hydrogen atom has an atomic mass of 1 dalton. Therefore, 23 hydrogen atoms make up the same mass as one sodium atom.
One mole of sodium chloride is composed of one mole of sodium atoms. Therefore, 3.6 moles of sodium chloride would require 3.6 moles of sodium.
