Problem: Identify the specific element that corresponds to each of the following electron configurations.1s2 2s2 2p4

FREE Expert Solution

We’re being asked to identify the specific element that corresponds to each of the following electron configurations: 1s22s22p4


When finding the identity of the element, you’ll have to identify the atomic number of that element. Recall that every single element in the periodic table has a corresponding atomic number.

The atomic number of an element is always equal to the number of protons of that element. And when the element is neutral (charge = 0), the number of protons is equal to the number of electrons.

Neutral element:          Atomic number = # protons = # of electrons
