Step 1:I'll solve this step by step using the proper LaTeX formatting:
Step 2:: Understand the Atomic Symbol
- The top left number ($$20$$) represents the total number of protons and neutrons (mass number)
- The bottom left number (10) represents the number of protons
Step 3:: Calculate Number of Protons
- The atomic number (number of protons) is $$10
- This means a neon atom always has 10 protons
Step 4:: Calculate Number of Neutrons
- $$\text{Neutrons} = 20 - 10 = 10
- Mass number = Protons + Neutrons
Step 5:: Calculate Number of Electrons
- Therefore, neon has $$10$$ electrons
- In a neutral atom, the number of electrons equals the number of protons
Final Answer
A) Protons: 10, Neutrons: 10, Electrons: 10
