To understand the problem we have to get the electron configuration of silicon. 

To determine the number of valence electrons, core electrons, and unpaired electrons in a carbon atom, let’s first write its electron configuration.

Ground-state means that Silicon is in its lowest energy form (not in excited state). Carbon also has no charge (neutral element) which means that no electrons are removed or added in the atom.
