Question

what element is designated by the orbital diagram below?
a n atom would have only three electrons in the 2p orbitals.
n
o
f
ne
cl

Explanation:

Step1: Count the number of electrons

Count the electrons in each orbital. The 1s orbital has 2 electrons, the 2s orbital has 2 electrons, and the 2p orbitals have 5 electrons. So in total, there are \(2 + 2+5=9\) electrons.

Step2: Relate the number of electrons to the atomic number

In a neutral atom, the number of electrons is equal to the atomic number. An element with atomic number 9 is fluorine (\(F\)).

Answer:

C. \(F\)
