Question

How many of these elements have more first ionization energy than Boron?
$Li,Be,C,N,O,F,Ne$ .

Answer 1

Answer: 6

The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period.
Here the order of first ionization energy is as follows
$Ne>F>N>O>C>Be>B>Li$
Hence, six elements have more first ionization energy than boron.
