Distinguishing Metals and Nonmetals from the Atomic Number

CHEM-QVFSJK

Consider the elements with atomic numbers: 38, 11, 14, 35, 54, and 37.

Which of these elements are metals and which are nonmetals?

Hint: Since you are not given a periodic table, determine the electronic configuration for each element.

A

The elements with Z= 38, 37, and 11 are metals and the elements with Z=35 and 54 are nonmetals.

B

The elements with Z= 38, 37, and 11 are metals and the elements with Z=14, 35 and 54 are nonmetals.

C

The elements with Z= 38, 37, 14, 54, and 11 are metals and the element with Z=35 is a nonmetal.

D

The elements with Z= 38, 37, 14, and 11 are metals and the elements with Z=35 and 54 are nonmetals.
