Step 1: Determine the number of protons in helium.
In an element, the atomic number is equal to the number of protons. For helium, the atomic number is 2. Therefore, there are 2 protons in a helium atom. \boxed{\text{Number of protons} = 2}
Step 2: Determine the number of neutrons in helium.
The number of neutrons in a nucleus is called the neutron number. Since we are assuming the most common isotope, Helium- 4, the neutron number is also 2. \boxed{\text{Number of neutrons} = 2}
Final Answer
For helium, - Number of protons: 2 - Number of neutrons: 2 (assuming Helium- 4) - Number of electrons: 2 - Element symbol: He - Atomic mass: 4.002602 u
