Sidney Vargas · Answer 1

D. They have very similar properties.

Explanation:

A. They have the same atomic mass.

⇒ This is false, every element has a different atomic mass.

B. They have very different properties

⇒ This is false. elements in the same group have similar properties

C. They have the same atomic number.

⇒ Every element has a unique and different atomic number

D. They have very similar properties.

⇒ This is correct. Elements in the same group usually have similar properties, because they have the same number of electrons in the outermost electron shell.

Cabrera · Answer 2

Elements in the same group tend to have very similar properties (D). This is due to the number of valence electrons each group has.
