Electronic formula for the external energy level of a silicon atom.
| May 3, 2021 | education
Silicon is an element that is at number 14 in the periodic table of chemical elements of D.I. Mendeleev.
He is in group 4 and period 3. This means that at the external energy level it has 4 electrons, and its total levels are 3. Following the rule of Hund, Pauli and Klechkovsky according to the sequence of distribution of electrons at energy levels, we will distribute these electrons:
1s2 2s2 2p6 3s2 3p2.
Then on the external third level there will be, as already mentioned, 4 electrons. It’s 3s2 3p2
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
