In atomic form, hydrogen consists of…….X…… proton and ……..Y…… electron. X and Y are — Hydrogen Chemistry Question

💡 Solution & Explanation

# Atomic Structure of Hydrogen **Step 1: Identify the basic structure of a hydrogen atom** A hydrogen atom is the simplest atom in the periodic table. It consists of: - A nucleus containing subatomic particles - Electron(s) in orbitals around the nucleus **Step 2: Determine the number of protons (X)** Hydrogen has atomic number $Z = 1$, which means: $$\text{Number of protons} = 1$$ Therefore, $X = 1$ proton **Step 3: Determine the number of electrons (Y)** In a neutral atom, the number of electrons equals the number of protons (to maintain electrical neutrality): $$\text{Number of electrons} = 1$$ Therefore, $Y = 1$ electron **Step 4: Verify the answer** Atomic hydrogen: $1p^+ + 1e^- = $ neutral atom with charge = 0 ✓ **Answer: X = 1 (proton), Y = 1 (electron)** Option C correctly states that hydrogen contains **one proton and one electron** in its atomic form.
