Question

Which of the following elements are nonmetals? A. lithium (Li) and barium (Ba) B. palladium (Pd) and zinc (Zn) C. nitrogen (N) and sulfur (S) D. beryllium (Be) and magnesium (Mg)

Answer 1

C) Nittogen and Sulfur

If you look on a periodic table there is a black bold line that looks like a staircase. MOST elements to the right of that line is a nonmetal. (Some are metalloids)

Answer 2

Answer:

C. Nitrogen (N) and sulfur (S)

Explanation:

Hello,

In this case, we could differentiate the nonmetals from the metals by understanding they do not have or have very tiny values of properties such as bright, hardness, electric conductivity, heat conductivity and others. Moreover, they are allocated at the right of the periodic table. In such a way, since nitrogen tends to be a gas and sulfur a yellowish powder, they are classified as nonmetals whereas, lithium, barium, palladium, zinc, beryllium and magnesium are considered as metals as they have the aforementioned properties.

Best regards.
