Over [174]

C) They each form similar compounds when combined with oxygen.

Explanation:

The given elements have a common characteristics as they each form similar compounds when combined with oxygen.

Beryllium, magnesium and calcium all are located in the alkaline earth group.

Elements in the same group have the same chemical properties.

  • Density and melting point are physical properties of matter which varies down a group on the periodic table.
  • Their reaction with oxygen denotes a statement of their chemical properties.
  • Chemical properties of matter is a function of their valency.
  • Group two elements have a valency of two. They have two electrons in their outermost shell.
  • Therefore, they all form ionic bonds when they react with oxygen.
