Question

question 9
the main group nonmetals generally follow the octet rule when forming covalent bonds while the ____________ elements do not.
transition and inner transition
prictogens
metalloids
halides and chalcogens

Explanation:

Main - group non - metals follow the octet rule in covalent bonding. Transition and inner - transition elements have d or f orbitals available and often do not follow the octet rule due to their ability to form bonds using these orbitals. Pnictogens, metalloids, halides, and chalcogens are main - group elements that generally follow the octet rule in covalent bonding.

Answer:

transition and inner transition
