Noble gasses rarely form compounds. They are in the 18th period. He, Ne, Kr are few examples.
Group 18 elements, which are also known as noble gases, rarely form chemical compounds.
no under special conditions xenon forms compounds such as XeF2, XeF4, XeOF4 , XeF6 etc
Periodic table contains list of elements and not compounds. Alkaloids are a group of naturally occurring chemical compounds that contain mostly basic nitrogen atoms. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and more rarely other elements such as chlorine, bromine, and phosphorus.
group 1 elements.
The Nitrogen Group.
Group 18 elements, which are also known as noble gases, rarely form chemical compounds.
They are the noble gases whose outermost (valency) orbitals are full.
Usually salts, from the metallic elements in group 1. However, note that hydrogen is also in group 1 and can not form salts, although it forms many other kinds of compounds.
Group 8 rarely forms ions since it has steal/lose more electrons to follow the octet rule (having eight valence electrons).
no under special conditions xenon forms compounds such as XeF2, XeF4, XeOF4 , XeF6 etc
group 17
They are the noble gases. They have 8 valence electrons, so that means that they are stable, and they rarely make bonds with any other elements or compounds.
Group 18 is the group farthest to the right on the periodic table. The elements in group 18 are also known as the noble gases. Noble gases are gases at standard temperature and pressure. Also, since they have their full complement of valence electrons they rarely make compounds with themselves or other elements.
A group of elements that rarely combine with other elements because they already have eight electrons in the outer shells is a Noble Gas

The transition metals tend to form colored compounds.
