The group on the far right of the Periodic Table of elements will not bond to form compounds. These are the Noble Gases aka Inert Gases and are the elements of Group 18, which includes helium, neon, argon, krypton, xenon, radon, and element 118. I think that's all of them. I am not 100% confident that this list is entirely inclusive so there may be some other element(s) that do not form compounds. I am sure however that Noble Gases do not react due to the fact that their electron shells are full.
There is no group in the periodic table which does not form compounds. Until recently the noble gases were thought not to, but some compounds have been synthesised which contain noble gase - particularly compounds containing xenon eg xenon hexafluoroplatinate.
Need to be restated...Which elements are not the product of compound decomposition?
Is this the question? I could only guess the high Atomic number elements.
These are the noble gases: the have the outer shell of electrons full.
Group 18 elements, which are also known as noble gases, rarely form chemical compounds.
group 1 elements.
Group 16
The elements in a column on the periodic table form a group (or family) because they have similar physical and chemical properties.
Noble gases do not normally form compounds.
Noble gases or group 18
Yes They do They all form compounds with Hydrogen
Group 18 elements, which are also known as noble gases, rarely form chemical compounds.
group 1 elements.
they will lose electron to form mono positive cation
Groups 1 and 17.
Alkaline Earth metals
Group 16
They're metals that form alkaline compounds when they react with water.
The elements in a column on the periodic table form a group (or family) because they have similar physical and chemical properties.
They have an octet of outer electrons, so they are stable. They do not tend to form any compounds.
Elements from the group 2 of the periodic table form cations.
