Study Notes
Sulfur Ion
- Sulfur has 16 protons and is represented by the symbol S.
- An ion of sulfur with 18 electrons has a charge of 2−, denoting it as the sulfide ion (S2−).
Calcium and Chlorine
- Calcium is a metal located in Group 2A with 2 valence electrons.
- Chlorine is a nonmetal in Group 7A with 7 valence electrons.
- Calcium loses 2 electrons to achieve an octet, while chlorine gains 1 electron.
- Resulting ions are Ca²⁺ (calcium ion) and Cl⁻ (chloride ion).
Ionic Compound Formation
- The ionic formula for the compound formed by Ba²⁺ and Cl⁻ is BaCl₂.
- Charges balance as 1(2+) + 2(1−) = 0.
Ionic Compounds from Cations and Anions
- Sodium and oxygen form sodium oxide (Na₂O) as 2Na⁺ and O²⁻ balance.
- Aluminum and chlorine yield aluminum chloride (AlCl₃) balancing 1Al³⁺ with 3Cl⁻.
- Magnesium and nitrogen create magnesium nitride (Mg₃N₂) balancing 3Mg²⁺ and 2N³⁻.
