How Many Atoms Are In Nacl
How many atoms are in NaCl?
Sodium Chloride or NaCl is made up of two elements, sodium (or Na) and chlorine (or Cl). A molecule of sodium chloride, NaCl, consists of one atom each of sodium and chlorine. Hence, each molecule of NaCl has 2 atoms total.
Similarly, we can calculate the total number of atoms in 1 mole of sodium chloride. Since 1 molecule contains 1 atom each of Na and Cl, 1 mole of NaCl will contain 1 mole each of Na and Cl. We know that 1 mole of anything contains an Avogadro's number of atoms or 6.023 x 10^23 atoms.
Thus, 1 mole of NaCl will contain 6.023 x 10^23 atoms each of Na and Cl, or a total of 12.046 x 10^23 atoms.
NaCl is an ionic compound formed by the loss of one electron from Na and the gain of the one electron by Cl. It is also known as common salt.
Hope this helps.
When looking at a compound represented by symbols, it is easy to count how many atoms is involved. The symbol Na stands for sodium. Na is not followed by a number and a number does not come before the symbol, so there is only 1 atom of sodium(Na). The same goes for Cl. There is 1 atom of chlorine. 1 sodium atom plus 1 chlorine atom equals 2 total atoms to make up NaCl (sodium chloride).
