Group 18 (noble gases), because there outer energy level is full
Noble gases or group 18 elements
No. Pyromanium is not an element. I have never even heard of it. you might want to check if pyromanium even exists.
It is an actinoid as it lies between Ac and Lr. However, as far as groups go, being in the Actinoid group doesn't say a great deal about your chemical properties. So it's fairly inconsequential as far as elemental families go.
The idiot before me wrote, : [Fl used to Fluorine, some old teachers might still use it. Now it goes by F.] Fl has never been used for fluorine, Fl is Flerovium (Previously Ununquadium (Uuq))
Potassium Nitrate is a compound. The transition metals are found in groups 4-12 of the Periodic Table
Noble gases or group 18 elements
It does have a name. Group 16 elements are called "chalcogens".
Hafnium is an element not a rock. Hafnium is never found in nature pure form so does not fit into any groups. Hafnium is a chemical element, a metal placed in the group 4 and period 6 of the periodic table of Mendeleev.
No. Pyromanium is not an element. I have never even heard of it. you might want to check if pyromanium even exists.
They are named as Group(I) in the Periodic Table. However, they are also known as the Alkali Metals. They are Lithium, Sodium, Potassium, Rubidium, Caesium, and Francium. Francium is never found in the open lab, as it is radio-active.
Group 1 (alkali metals) and Group 17 (halogens) in the periodic table contain elements that are highly reactive and are never found in their free state in nature. Alkali metals readily react with water or air, while halogens are highly reactive nonmetals that form compounds with other elements quickly.

This is to my opinion not very probable, though never say impossible: Today Mendelejev's Periodic Table looks rather incomplete, there were no 'transition' elements in it (group 3 - 12)
Francium is an alkali metal, similar to caesium. Water (H2O) is a compound,not an element. Francium, although it is believed to have never been tested, is thought to have been the most reactive element with water. It is among the alkali metals in group 1 on the periodic table of elements.
Group 18 is the Noble Gas Family. Since the outer energy level of all elements in the family are full they never bond except at extremely cold temperatures close to absolute zero.

Group 5A (or VA) of the periodic table are the pnictogens: the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metal bismuth (Bi). The name "pnictogen" is not in common usage; it derived from the Greek work pnigein, "choke" or "stifle," which is a property of breathing pure nitrogen gas.The Group 5A elements have five valence electrons in their highest-energy orbitals (ns2np3). Nitrogen, phosphorus, and arsenic can form ionic compounds by gaining three electrons, forming the nitride (N3-), phosphide (P3-) and arsenide (As3-) anions, but they more frequently form compounds through covalent bonding. Antimony and bismuth can lose either their outermost p electrons to form 3+ charges, or their outermost s and p electrons to form 5+ charges.Compounds of Group 5 ElementsThe title of this lesson doesn't really do the topic justice. Compounds made from elements in Group 5 of the periodic table can help athletes increase endurance and build muscle. They're involved in making chemical weapons used in war. And, you might even them find in your favorite beverages.
