What is the oxidation number for all the elements in the carbon group?
You are asking about group 12. Generally they shows 14 as the oxidation number.
What is the group name of group number eighteen in the periodic table?
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.
What group has variable oxidation numbers?
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!
Where in the periodic table are found semiconducting elements?
The fourth group elements. Especially Silicon with atomic number 14 and Germanium with atomic number 32 are the semi conducting materials.
What do all group 14 elements have in common periodic table?
All the Group 14 elements has 4 electrons in its outer energy level.

Group 14 is known as carbon family as the first element in the group is carbon.
What group is pb?

There is a total of 17 elements in those groups.
Which of the group IVB 14 metals is the least active?
These elements are hafnium and zirconium.
Why do elements in group 4A do not form ionic bonds?
Group-14 elements share electrons. they form covalent bonds.
