Respuesta :
The following element occurs as diatomic molecules by completing their octets.
What is octet?
The octet rule is a chemical rule of thumb that reflects the theory that main- group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
- When two hydrogen atom pair together, they form a single bond to complete their octet.
H+H ⇒ H-H ⇒ H₂
- When two halogen like fluorine, Fl (each with a valency of 7) atoms form a singe bond to achieve a complete octet which is stable. Each Fl atom will contribute 1 electron each to form a single bond.
Fl+Fl ⇒ Fl-Fl ⇒ Fl₂
- When two oxygen atoms pair together, a double bond is formed to achieve a complete octet which is a stable configuration.
O+O ⇒ O=O ⇒ O₂
- When two nitrogen atom, pair together, they form a triple bond between them to achieve a complete octet which is a stable configuration.
N+N ⇒ N≡N ⇒ N₂
