A. Metalloids border on the line.
B. It separates the nonmetals from the metalloids.
C. Nonmetals border on the line.
D. Metals border on the line.

1 Answer
A, F.
Explanation:
F. The line separates metals from nonmetals.
Metals with low electronegativity that tend to form positively charged ions are on the left side of the line. Nonmetals with high electronegativity that tend to form negatively charged ions are on the right side of the line.
A. metalloids are on both sides of the line. metalloids tend to have some metallic properties and some nonmetal properties. Silicon is an excellent example of a metalloid. Silicon can be +2,+4, -4 -2. Silicon is used in computers because of its ability to shift from positive ( metallic property) to negative ( nonmetal property),
B. is wrong the line separates metals from nonmetals, not metalloids.
C. nonmetals do not border the line they are on the right of the line.
D. metals do not border the line the line they are on the left side of the line
E. is wrong the line separates the metals from the non-metals not metalloids.
