Answer:
Explanation:
Remember that the atomic number of an element is the number of protons and the mass number is the number of protons plus neutrons.
1) <em>Deuterium</em> representation:
- Hydrogen: ⇒ H
- One proton: ⇒
- One neutron: ⇒ add 1 to the mass number = 1 + 1 = 2 ⇒
2) <em>Helium-3</em> representation:
- He atom with 1 neutron: ⇒ mass number = 2 + 1 ⇒
3) <em>Neutron </em>representation
- Atomic number 0 and mass number 1: ⇒
4) Nuclear equation:

Answer:
Explanation:
First consider the mol to mol ratio, the mol of a substance is simply the count of atoms in respect to avagadros number (approx. 6.02 × 10²³ molecules) in the period table. 1 mol of an element is simply it's mass count in the periodic table.
