What is Na atom made of?

Sodium is a chemical element; it has symbol Na (from Latin natrium) and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table.

How do you find the number of atoms?

the number of atoms = the number of moles × Avogadro’s number 1 mole Sn = 1.685 × 10 − 2 moles Sn × 6.022 × 10 23 atoms 1 mole Sn = 1.015 × 10 22 atoms There are 1.015 × 10 22 atoms in 2g of Tin(Sn).

How many atoms are in 1 mol of Na?

Since 1 mol Na = 6.02 × 1023 atoms Na, the two unit factors are 1 mol Na/6.02 × 1023 atoms Na, and its reciprocal 6.02 × 1023 atoms Na/1 mol Na.

How many atoms are there in 46g of Na?

∴ 46 g of Na contains 12.044×1023atoms.

Why is sodium atomic number 23?

The atomic number of sodium is 11, while the number of neutrons in its nucleus is 12. Sodium’s atomic mass is 11 + 12 = 23. As a result, 1 mole of sodium equals 23 grams. We know that because sodium’s atomic mass is 23, we can write it as 23 g/mol.

Does Na have 11 protons?

An atom of sodium has 11 protons, 11 electrons, and 12 neutrons.
