Study Notes
Bonding in Compounds
- In the molecule CaCl, an ionic bond is formed between Ca and Cl, where Ca loses an electron to form a cation and Cl gains an electron to form an anion.
- Ca is described as an electropositive element.
- In the molecule NaCl, an ionic bond is formed between Na and Cl, where Na loses an electron to form a cation and Cl gains an electron to form an anion.
- In the molecule MgO, an ionic bond is formed between Mg and O, where Mg loses electrons to form a cation and O gains electrons to form an anion.
- Chlorine shows a valency of 1 with hydrogen, forming a covalent bond with H.
