Question
write the electron configuration for the first excited state of He^+
Determine the member of each of the following pair of atoms that has the larger radius (only using periodic table)
a) O and F b) Kr and Xe
c) F and Cl d) Mg and Ca
Expert Solution
Step 1
He has 2 electrons
its electronic configuration is 1s2
but in an excited state, its configuration is 1s1 2s1
so, when it loses an electron and become He+
it will have only 1 electron left.
so, its excited state electronic configuration is 1s1.
