-4 for nonmetals and +4 for metals
Group 14 has 4 valence electrons
+4 and -4 are most common
Potato.
You are asking about group 12. Generally they shows 14 as the oxidation number.
Group 17 elements are also known as halogens. Atomic halogens have 0 as their oxidation number. They tend to accept an electron from another element to become stable: the new oxidation state would be -1.
Groups 1 and 2 are +1 and +2 respectivelly.. Group 3-12 have variable oxidation numbers - they are the so-called transition metals. Group 14-17 have variable oxidation numbers -even group 18- has- there are a number of different compounds of Xe for example. Group 1 and 2 have some strange compounds such as Cs11O3 . A better question might be which group doesn't have variable oxidation numbers!
The fourth group elements. Especially Silicon with atomic number 14 and Germanium with atomic number 32 are the semi conducting materials.
All the Group 14 elements has 4 electrons in its outer energy level.

Four, as with all other elements of Periodic Group 14.
Group 14 is known as carbon family as the first element in the group is carbon.
Lead is in the group 14 of the Periodic Table of elements.
There is a total of 17 elements in those groups.
These elements are hafnium and zirconium.
Group-14 elements share electrons. they form covalent bonds.
