A silicon atom has fourteen electrons. In the ground state, they are arranged in the electron configuration [Ne]3s 3p . Of these, four are valence electrons, occupying the 3s orbital and two of the 3p orbitals. Like the other members of its group, the lighter carbon and the heavier germanium, tin, and lead, it has the same number of valence electrons as valence orbitals: hence, it can complete its octet and … WebApr 3, 2024 · Silicon has variety of different allotropes but the two most common allotropes are amorphous silicon (a-Si) and crystalline silicon (c-Si). Allotropes …
