Step 2:: Understand the Atomic Structure of Helium
Helium is an element with an atomic number of 2, which means its nuclear composition can be determined from its position on the periodic table.
Step 3:: Determine the Number of Protons
- For helium, the number of protons = $$2
- The number of protons is equal to the atomic number
Step 4:: Determine the Number of Electrons
- For helium, the number of electrons = $$2
- In a neutral atom, the number of electrons equals the number of protons
Step 5:: Determine the Number of Neutrons
- $$4 - 2 = 2$$ neutrons
- The most common isotope of helium is helium- 4 - Helium- 4 has a mass number of 4 - Number of neutrons = Mass number - Number of protons
Final Answer
- Protons: 2 - Neutrons: 2 - Electrons: 2
