Answer:
an equal number of atoms
Explanation:
One mole of a substance contains the Avogadro's number of elementary entities (Atoms, molecules, ion, etc).
Hence, one mole of calcium and one mole of neon will contain exactly the same number of atoms which is 6.02 *10^23 atoms. This is known as the Avogadro's number.
Comparing 1 mole of Neon to 1 mole of calcium, both substances contains
6.0221 x 10²³ atoms.
The atomic number of neon is 10 and the atomic number of calcium is 20.
The atomic number of an atom is the number of proton of an atom.
1 mole of Neon can be represented as follows
Ne
1 mole of Calcium can be represented as follows:
Ca
Avogadro's number, or Avogadro's constant, is the number of particles found in one mole of a substance.
This experimentally determined value is approximately 6.0221 x 10²³ particles per mole.
This means 1 mole of any substance contain 6.0221 x 10²³ atoms.
Comparing 1 mole of Neon to 1 mole of calcium, both substances contains
6.0221 x 10²³ atoms.
