Carbon and Silicon both have four valence electrons as well as other group four elements.
number of electrons in the bonding shell vary according to the element. for example group 1 in the periodic table contains elements with ony one electron in their bonding shell, similarly group 2 has elements with two electrons in its bonding shell and so on. the group number in the periodic table denotes the number of electrons in the bonding shell of each element present in that particular group
Each potassium atom has one valence electron available for bonding.
There are 32 electrons available for bonding in the sulfate ion (SO4^2-). Each oxygen contributes 6 valence electrons, and the sulfur contributes 6 valence electrons, giving a total of 32 electrons.
A sulfate ion consists of one sulfur atom, four oxygen atoms, and two "excess" electrons from another source. Each sulfur atom has 16 electrons, each oxygen atom has 8 electrons, so that the total is 16 + (4 X 8) + 2 = 50. The question of "bonding electrons" is not quite so clear. When acting as an ion, each sulfate ions has two electrons available for ionic bonding. Internal bonding within each sulfate ion is generally supposed to correspond to two sulfur-oxygen double bonds with four bonding electrons each, two sulfur-oxygen single bonds with two bonding electrons each, and the two excess electrons, for a total of 14.

Two bonding electrons are in the molecule of H2O (light water)
The valence electrons are the electrons in the partially filled outermost shell (or shells).Simplified; Oxygen has the shells filled in the following way.1s22s22p4The 2s and 2p subshells make up the outer most shell for oxygen. In the 2p subshell, It is stable with 6 electrons but with oxygen only has 4. The subshell has 3 different orbitals which can contain 2 electrons in each. This means that 1 of the orbitals is completely full while the other two only have one electron. From this we can say that there are 2 bonding valence shell electrons. Because there is a possibility of having a total of 8 electrons in the 2nd shell, this means that there must be 4 electrons which are non bonding in oxygen's valence shell.
In silicon, each silicon atom can form bonds with up to four hydrogen atoms. This is because silicon belongs to group 14 of the periodic table, which means it has four valence electrons available for bonding.
In the structure of CO2, there are 2 bonding electrons between each carbon and oxygen atoms, connecting them. There are no nonbonding electrons in the CO2 molecule because all the valence electrons are involved in bonding either between carbon and oxygen or within the oxygen atoms themselves.
Electrons are the most important element in atom bonding. Each element has an atomic number based on the number of electrons, and it is the was these different numbers of electrons link up to each other that determines how closely they will bond.
The outer or valence electrons are the ones involved in bonding.Valence electrons
