We are asked to determine the number of valence electrons in indium, In.
Let’s first write its electron configuration.
Ground-state means that it is in its lowest energy form (not in excited state). It also has no charge (neutral element) which means that no electrons are removed or added in the atom.
Neutral element: Atomic number = # protons = # of electrons
▪ Atomic number = 49
▪ # of electrons = 49 e-
How many valence electrons does indium, In, have and what are its specific valence electrons?
