The shaded region represents elements that belong to which group of the periodic table? Identify an element that forms an ion with a +2 charge. Which non-metal is the most reactive? Where would elemen

Here are the solutions to the questions:

1. a) The name of the elements represented by the shaded region is transition metals.

1. b) An element which forms an ion with a +2 charge is J (or B or W, as they are in Group 2).

1. c) The most reactive non-metal is K.

1. d) Element V is in the second period and group V (Group 15). It would be placed in the grid in the row containing S, R, K, and in the column directly above P.

1. e) J has a larger atomic radius than U.
Atomic radius generally decreases across a period from left to right. J
