About This Product
Teachers use the model to tie atomic number to a structure students can turn and inspect from any side. Its outer shell of four electrons explains why silicon has a valency of 4 and can form up to four covalent bonds, which leads into its place in Group 14 and its role in semiconductors such as microchips and transistors.
Frequently Asked Questions
What electron configuration does the Silicon Electronic Configuration Model show?
It shows 14 electrons in three shells: 2 in the first, 8 in the second and 4 in the outermost shell, which are the valence electrons.
How are protons and neutrons shown in the nucleus?
The nucleus holds 14 protons and 14 neutrons, picked out in distinct colours so students can tell them apart.
