Covalent bonding: sharing electrons — Homework
Count total electrons around each atom (bonding pairs plus lone pairs) to confirm every octet.
- 1.Fluorine gas, F2: each F has 7 valence electrons, needing 1 more. What type of bond forms?
- 2.Describe the Lewis structure of ammonia, NH3 (nitrogen has 5 valence electrons, bonds singly to 3 hydrogen atoms).
- 3.Why does hydrogen only need 2 electrons instead of 8 like most other atoms?
- 4.Explain why oxygen gas, O2, forms a double bond rather than a single bond between its two oxygen atoms.
