Answers

Answer 1

Answer:

Group 1

Explanation:

The alkali metals are the most reactive metals found on the periodic table

Answer 2

In a periodic table, the most reactive metals are found in Group 1, the first column on the left. (option a)

The most reactive metals are found in Group 1, which is the first column on the left side of the periodic table. Group 1 is also known as the alkali metals. These metals include elements like lithium (Li), sodium (Na), and potassium (K). Alkali metals are highly reactive because they have only one electron in their outermost energy level.

This means they are eager to lose that electron and achieve a stable electron configuration, which makes them more likely to engage in chemical reactions.

As we move down Group 1, the reactivity increases because the outermost electron is farther from the positively charged nucleus, making it easier to lose.

Hence the correct option is (a).
