Analyze the photoelectron spectra of $Be$ and $B$.
Which of the following is the BEST reason for the energy of the first peak to increase from 11.5 eV to 19.3 eV between the two elements?
$B$ has a higher effective nuclear charge than in $Be$.
$B$ has more electrons farther away from the nucleus than $Be$.
$Be$ has two valence electrons, while $B$ only has one.
$B$ is a more stable atom then $Be$.
