Direct answer
Silicon (Si)
Key terms
- Ionization Energy: The energy required to remove an electron from an atom in the gaseous state.
- Molar Mass: The mass of one mole of a substance, typically expressed in grams per mole (g/mol).
Common trap
Confusing trends in atomic radius and ionization energy: Remember that atomic radius decreases across a period while ionization energy increases due to increased nuclear charge.
