Describe the properties of alkaline earth metals. Based on their electronic arrangement, explain whether they can exist alone in nature.

See explanation

Explanation:

Alkaline earth metals are metals of group two. They are divalent metals and they have a highly negative reduction potential hence the metals are mostly extracted by electrolysis.

They are highly reactive metals. They react with water but do so less readily than alkali earth metals.

Owing to their high reactivity, they are seldom found free in nature. They always occur in combined state with other highly reactive nonmetals.

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
