Solution: What is the atomic number of the as yet undiscovered element in which the 8s and 8p electron energy levels fill?

Problem

What is the atomic number of the as yet undiscovered element in which the 8s and 8p electron energy levels fill?

Solution

The atomic number of an element is equal to the number of its protons.

In an uncharged species, the number of protons of an element is also equal to the number of its electrons.


Atomic Number, Z = # of protons

# of protons = # of electrons
