Question

What common characteristic is generally shared by the elements at the center of a period?

A. They are nonmetals.


B. They have the lowest atomic mass.


C. They are the least reactive elements.


D. They have the most orbitals.

Answer 1

C. they are the least reactive elements.

Answer 2

I think the correct answer would be C. The common characteristic that is shareed by the elements found at the center of a period would be that they are the least reactive species. Having lower value of electronegativity, there is less ionization of the atoms which would also contribute to less reactivity.
