The number of electrons in the valence shell of an element of atomic number 14 is?
Answer Details
The number of electrons in the valence shell of an element can be determined by using the periodic table and the electron configuration of the element. The valence shell is the outermost shell that contains electrons that are involved in chemical reactions.
For an element with atomic number 14, which is silicon, the electron configuration is 1s2 2s2 2p6 3s2 3p2. The valence shell of silicon is the third shell, which contains 3s2 and 3p2 electrons.
Therefore, the number of electrons in the valence shell of silicon is 4 electrons.
