Señala cuál es el nombre y el símbolo de los elementos cuyas configuraciones son: a) 1s2 2s2 2p2 b) 1s2 2s2 2p2 3s2
c) 1s2 2s2 2p6 3s2 3p6
d) 1s2 2s2 2p6 3s2 3p6 4s2 3d1

It is called a neutralization reaction

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
