Post-UTME Biology 2011 Objective — Question 17

Question 17 of 24 from the Post-UTME Screening (Post-UTME) Biology 2011 Objective paper, with the correct answer and a full explanation.

Four elements P, Q, R and S have 1, 2, 3, and 7 electrons in their outermost shells respectively. The element which is likely to be a metal is

A. PCorrect
B. Q
C. R
D. S

Explanation

Fewer outer-shell electrons (here, P with 1) makes an element more likely to lose electrons easily - a metallic property. (Note: this question is a near-duplicate of one found in the FUTO 2013/2014 Type D session in this same PDF set; the same independently-worked answer is used here.)
