Problem

The atomic radius (in pm) of consecutive Period 2 elements is plotted against atomic number as follows:

Z=3\;(167),\;4\;(112),\;5\;(87),\;6\;(67),\;7\;(56),\;8\;(48),\;9\;(42),\;10\;(?).

Based on the trend in the plotted data, which value is most reasonable for the atomic radius of the element with

Z=10

? (a) 48 pm (b) 38 pm (c) 70 pm (d) 45 pm
