Answer:

D. Lithium is the least reactive element in group 1, because it is the smallest and holds its valence electron more tightly than the others in the same group.

Explanation:

Lithium is at the top of group one and has only two energy levels. It has the smallest atomic radius of all the elements in group one. This means it's valence electron is the closest one to the nucleus of all the group 1 elements. The nucleus holds this electron more tightly than other group 1 nuclei which is why lithium is the least reactive of all the group 1 metals.

lakkis [162]
Natural selection and selective breeding can cause both animal and plant changes. The distinction between the two is that natural selection occurs without human intervention, while selective breeding occurs only when humans interfere. As a result, selective breeding is also known as artificial selection.
