Question

1. what family is the most reactive group of metals? (0.5 points) *

transition metals
lanthanides
halogens
oxygen group
carbon group
alkali metals
alkaline earth metals
nitrogen group
actinides
boron group
noble gases

Explanation:

Alkali metals (Group 1 in the periodic table) have one valence electron. They readily lose this electron to form +1 ions, making them highly reactive. Transition metals (d - block elements) have variable oxidation states and are less reactive than alkali metals. Lanthanides (f - block, rare earth metals) are relatively stable. Halogens are non - metals. The oxygen group, carbon group, nitrogen group, boron group have non - metallic or metalloid character in some cases. Alkaline earth metals (Group 2) have two valence electrons and are less reactive than alkali metals as they need to lose two electrons. Actinides are radioactive and have complex chemistry but are not the most reactive metals. Noble gases are inert.

Answer:

Alkali metals
