the group 4A elements
If an element has less than four valence electrons, it will tend to lose its valence electrons and form cations. If an element has more than four valence electrons, it will tend to gain electrons and form anions. An element that has four valence electrons will tend to form covalent bonds rather than ionic bonds.
Carbon has four valence electrons. Each of theseelectrons can pair with an electron from another atom to form a strong covalent bond. In carbon, all the electrons with the principal quantum number 2 are valence electrons, but the two electrons with principal quantum number 1 are not.

They r noble gases which have stable valance shell and grotp no. 18
Sn has 50 total electrons and is in the Group 4a elements on the periodic table. The nearest Noble Gas that is before Sn is Kr, which has 36 electrons. Therefore, the number of inner electrons (the same as Kr's electrons) is 36, outer electrons is 4 and valence is 4 as well (because its a Group 4a
Elements that contain four valence electrons include elements from group 14 of the periodic table, such as carbon (C), silicon (Si), germanium (Ge), tin (Sn), and lead (Pb). These elements have their outermost electron shell filled with four electrons and display a variety of chemical properties based on this electron configuration.
If an element has less than four valence electrons, it will tend to lose its valence electrons and form cations. If an element has more than four valence electrons, it will tend to gain electrons and form anions. An element that has four valence electrons will tend to form covalent bonds rather than ionic bonds.
All elements in group four have FOUR valence electrons. This is easy to remember because the group number located at the top of the periodic table of elements corresponds precisely in all cases to the experimentally observed number of valence electrons in the elements. It is also important to know that the elements in group eight (the inert gases) all have eight valence electrons, meaning that they can neither gain or lose electrons in the way of bonding with other elements, thus the maximum number of valence electrons any molecule can have is eight.
The most reactive elements have either 1 valence electron or 7 valence electrons
Carbon has four valence electrons. Each of theseelectrons can pair with an electron from another atom to form a strong covalent bond. In carbon, all the electrons with the principal quantum number 2 are valence electrons, but the two electrons with principal quantum number 1 are not.

Carbon typically shares 4 electrons to complete its valence shell, forming covalent bonds with other atoms. Carbon has 4 valence electrons, so by sharing these electrons with other atoms, it can achieve a full octet and become more stable.
Sn has 50 total electrons and is in the Group 4a elements on the periodic table. The nearest Noble Gas that is before Sn is Kr, which has 36 electrons. Therefore, the number of inner electrons (the same as Kr's electrons) is 36, outer electrons is 4 and valence is 4 as well (because its a Group 4a
Group 4 elements in the periodic table have four valence electrons. This includes elements like carbon (C), silicon (Si), germanium (Ge), tin (Sn), and lead (Pb).
There are four valence electrons because it is in 4A row. 5A 5 valence 6A 6 valence etc. Carbon has four.
Silicon has 4 valence electrons.
