We’re being asked to rank the elements in decreasing atomic radius .
Atomic radius represents the distance from the nucleus to the outer shell of an element.
The trend of the atomic radius in the periodic table:
• decreases going from left to right of a period
• increases going down a group
Which of the following correctly lists the five atoms in order of increasing size (smallest to largest)?
A) O < F < S < Mg < Ba
B) F < O < S < Mg < Ba
C) F < O < S < Ba < Mg
D) O < F < S < Ba < Mg
E) F < S < O < Mg < Ba
