Question

Determine which of the following elements would gain electrons when becoming ions:I. HydrogenII. HeliumIII. SulfurIV. FluorineV. GalliumA. I and IIB. I and VC. III and IVD. II, III, and IV

Answer 1

1) Ion. This refers to an atom or molecule that gains (anion) or loses (cation) electrons. In order to know which element would gain electrons more easily, we need to find the electronegativities.

Electronegativity: the tendency of an atom to attract electrons.

I. Hydrogen: 2.20

II. Helium: 0.00

III. Sulfur: 2.58

IV. Fluorine: 3.98

V. Gallium: 1.81

Sulfur and Fluorine would gain electrons more easily

Option C.
