What are Group 14 elements called?
Carbon group element
Which is more metallic silicon or germanium?
Germanium is more metallic in its behavior than silicon. Although tin has an even more metallic character than germanium, lead is the only element in the group that behaves purely as a metal.
What is the only nonmetal in group 1?
Explanation: Hydrogen is the only non metal in group on of the period table of elements.
What is the only nonmetal in Group 14?
Nonmetals can also form compounds with other nonmetals by sharing electrons. The elements in Group 14. They gain, lose, or share four electrons when reacting with other elements. Carbon is the only nonmetal element in the group and play an important role in the chemistry of life.
Is Group 2 metal or nonmetal?
Alkaline-earth metals: The alkaline-earth metals make up Group 2 of the periodic table, from beryllium (Be) through radium (Ra). Each of these elements has two electrons in its outermost energy level, which makes the alkaline earths reactive enough that they’re rarely found alone in nature.
Is group 8 metal or nonmetal?
Group 8 is a group (column) of chemical elements in the periodic table. It consists of iron (Fe), ruthenium (Ru), osmium (Os) and hassium (Hs). They are all transition metals.
What do the shells of Group 8 have in common?
It is very stable with only two electrons in its outer orbital (valence shell). Even though it only has two electrons, it is still grouped with the noble gases that have eight electrons in their outermost orbitals.
Is Group 7 metal or nonmetal?
the halogens
Is group 6 metal or nonmetal?
It is a yellow nonmetal, and is found in a number of allotropic forms, including orthorhombic sulfur, monoclinic sulfur, etc. It forms rings containing anywhere from 4 to 20 atoms of sulfur; S8 is the most common form….Group 6A — The Chalcogens.

Which is the most unreactive group?
Group 8A — The Noble or Inert Gases. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
Is group 3 metal or nonmetal?
Groups 3–12 contain transition metals. They are less reactive than metals in groups 1 and 2. Groups 13–16 each contain at least one metalloid.
