Question

Which if the following groups of elements is arranged correctly in order of increasing ionization energy?a. C< Si< Li< Neb. Ne < Si< C< Lic. Li < Si< C< Ned. Ne < C< Si < Li

Answer 1

Answer

The correct answer is D - Ne < C< Si < Li

Explanation

The ionization energy increases across a period but decreases down a group.

Ne is on your far right of the periodic table, it has the highest ionization energy. Between C and Si, C has the highest ionization energy because it is at the top of Si. Li is at your left thus it has a smaller ionization energy.
