Final answer:
The electron configuration for silicon is 1s2 2s2 2p6 3s2 3p2.
Step-by-step explanation:
The electron configuration for silicon is 1s22s22p63s23p2. In simpler terms, this means that there are:
- 2 electrons in the 1s orbital
- 2 electrons in the 2s orbital
- 6 electrons in the 2p orbital
- 2 electrons in the 3s orbital
- 2 electrons in the 3p orbital
The electron configuration shows how electrons are arranged in different energy levels and orbitals around the nucleus of an atom. In the case of silicon, the 3p orbital is the outermost shell, which means that it has 4 valence electrons. These valence electrons are responsible for the chemical properties and reactions of silicon.
