Problem: Write full orbital diagrams for each of the following elements.He

FREE Expert Solution

Recall that for a neutral element, Atomic number = # of protons = # of electrons


The atomic number of He is 2 and since it’s a neutral element, this means He has 2 electrons.


The location of He in the periodic table is shown below:



Based on the figure, Ni belongs in the s-block in Period 1 so its electron configuration will only contain the 1s subshell. Recall that: 

s–subshell can hold a maximum of 2 electrons

p–subshell can hold a maximum of 6 electrons

d–subshell can hold a maximum of 10 electrons
