helium and hydrogen
The periodic table lists the elements and not compounds. Butane, C4H10, is an organic molecule / compound and hence is not present on the periodic table. The elements that make up butane (carbon and hydrogen) are present on the periodic table. Carbon: group 14, period 2 Hydrogen: group 1, period 1 Besides, group 2 elements are alkaline earth metals.
group 1 elements.
Hydrogen is found in group 1 row 1 of the periodic table
The abbreviation for potassium is " K " in the periodic table. It is placed in group-1 of the periodic table.
The alkali metals are group 1 on the periodic table.
they are found as element because in group 1 they react
I think what you are asking is about is which group on the periodic table has elements with an oxidation number of -1 in most ionic compounds. That is the 17th group - the halogens.

Groups 1 and 17.
Francium is amrmber of the alkali metal familiy (group 1 in the Periodic Table of Mendeleev): Li, Na, K, Rb, Cs, Fr.
Actually group 1 is ALL elements and so is the whole periodic table.
MX is the general formula where M is the alkali metal and X is the halogen.
The abbreviation for potassium is " K " in the periodic table. It is placed in group-1 of the periodic table.
The alkali metals are group 1 on the periodic table.
It is in group 18 of the periodic table
