the element with the electron configuration 1s²2s²2p⁶ is
a f
b p
c ne
d b

Explanation:

The sum of electrons in the given configuration $1s^{2}2s^{2}2p^{6}$ is $2 + 2+6=10$. Neon (Ne) has an atomic number of 10, which means it has 10 electrons. Fluorine (F) has 9 electrons, phosphorus (P) has 15 electrons and boron (B) has 5 electrons.
