Question

2 which family is the most reactive? noble gas transition metal alkali metal alkaline earth metal 3 match the type of ions the family makes noble gas alkali metal transition metal alkaline earth metal halogen

Explanation:

Alkali metals are highly reactive due to having only one valence - electron which they can easily lose to achieve a stable electron configuration. Noble gases are very stable and unreactive as they have a full outer electron shell. Transition metals have variable reactivity. Alkaline earth metals are reactive but less so than alkali metals. Halogens are also reactive but in a different way as they gain electrons to achieve a stable configuration. For ion - formation, noble gases generally do not form ions as they are already stable. Alkali metals form + 1 ions by losing their single valence electron. Transition metals can form ions with various charges. Alkaline earth metals form + 2 ions by losing their two valence electrons. Halogens form - 1 ions by gaining one electron to complete their outer shell.

Answer:

1. C. Alkali Metal

3.
Noble Gas: Do not form ions easily
Alkali Metal: + 1 ions
Transition Metal: Variable - charged ions
Alkaline Earth Metal: + 2 ions
Halogen: - 1 ions
