alkaline earth metals
Fluorine (F) is the most reactive element in group 7A (also known as group 17 or the halogens). It has a strong tendency to gain an electron to achieve a stable octet configuration, making it highly reactive.
Elements are more reactive as you go down the periodic table and to the left.
Nitrogen is a group 5A element that is highly reactive and essential for plant growth.
Group seven is known as the halogen group. The least reactive element in group seven is astatine. Fluorine is the most reactive.
group 1
Group 7. Fluorine, which belongs to group 7, is the most reactive element.
A metal group 13 element would be less reactive than an element in the Mg group 17. This is because elements in group 13 have three valence electrons, making them less likely to readily lose or gain electrons compared to Mg group 17 elements, which have seven valence electrons. Mg group 17 elements are more reactive due to their greater tendency to gain one electron to achieve a stable electron configuration.
