Question & Answer
Choose the Best Answer
They have the same number of valence electrons.
They have the same atomic mass.
They are all metals.
They have identical electron affinity values.
Understanding the Answer
Let's break down why this is correct
Elements in a group share the same number of outer electrons, called valence electrons. Other options are incorrect because Thinking that atomic mass decides chemical behavior is a misconception; Some think all elements in a group are metals.
