As far as "inert gases" (noble gases), the heaviest is the radioactive gas radon (atomic number 86, only natural isotope 222Ra).
Referring to "inert" precious metals, the heaviest is gold (atomic number 79). Precious metals are not non-reactive and may either oxidize or dissolve in acids.
What else can I help you with?
Where are the noble gases located on the periodic table?
The noble gases are located in Group 18 of the periodic table. They are known for being chemically inert and have a full valence shell of electrons, making them very stable and unreactive. The noble gases include helium, neon, argon, krypton, xenon, and radon.
Region of the periodic table where most radioactive elements are found?
Group 3 of the periodic table contains many of the radioactive elements.
What is a group in the periodic table called?
the vertical column is called group in the periodic table.
Which group on the Periodic Table of Elements has the most reactive nonmetals?
group 17 or halogens
What does HE stand for in the peridoic table of elements?
"He" stands for helium in the periodic table of elements. It is a colorless, odorless, and tasteless gas that is the second lightest and second most abundant element in the observable universe. Helium is commonly used in balloons, airships, and cryogenic applications.
Where are the inert noble gases located in the Periodic Table?
group 18, the right most group on the periodic table
What is the name of group 18 elements in the periodic table?
it is 35
What is group one in the periodic table?
Alkali metals. This is the most reactive group on the periodic table
Where are the noble gases located on the periodic table?

Why are the elements in Family 18 called inert in the periodic table?
Inert means unreactive, and most of these gases never react.
What group is 1?
in the Periodic Table it is the most reactive metals!
What is the most reactive group of metals in the periodic table is the?
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
What group of elements on the periodic table is most reactive?
For the most part, the Halogen group is the most reactive group on the periodic table. However, the Alkali metals are just as equal but not quite.
Where is the most reactive metal on the periodic table located?
This element is francium in the first group of periodic table.
Where are the most reactive nonmetals located on the periodic table?
The most reactive nonmetals are located in top most right section of the Periodic Table, excluding group 18 (has no reactivity).
What family of the most reactive group of metals in the periodic table?
The Alkali metals are the most reactive group of metals in the Periodic Table. Of these Francium is the most reactive metal of all.
In the periodic table which group of element are the most reactive?
group 1
