What group of the region shown on the periodic table contains mostly elements that are gases at room temperature?

The so-called noble or inert gases are in Group 18, the last group on the right of the periodic table of the elements.


Which side of the periodic table contains noble gases?

right side, last group (or last column). Noble gases are group 18 elements.


What are Helium and neon classified as on the Periodic table?

these gases are the noble gases or inert gases. They are non reactive and have stable valence electrons


What is the last group on the periodic table with 8 valence electrons?

The last group on the periodic table with 8 valence electrons is the noble gases group. This group includes elements such as helium, neon, argon, krypton, xenon, and radon. Noble gases have a full outer electron shell, making them stable and unreactive.


Where on the periodic table are the noble metals located?

The noble metals are located in the last group on the right side of the periodic table, known as Group 18 or the noble gases group.


What is the last group in the periodic table called?

There are no 'rows' on the Periodic Table of the Elements.I assume you are talking about Group-18 of the table.Group-18 of the Periodic Table of the Elements are the noble gases. These elements have a full valence shell (8 electrons).


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.


The elements in group 18 of the periodic table?

Group 18 is the noble gases, the last group on the periodic table. The elements are Helium, Neon, Argon, Krypton, Xenon, and Radon. These elements have a full outer shell and are virtually nonreactive.


Why is helium located in the last colunm?

Because helium has completely filled orbitals as do all the elements in the last column (group 18 elements or noble gases).


What is a possible last sublevel for an element found in group 18 the periodic table?

A possible last sublevel for an element in group 18 of the periodic table (noble gases) is f. The noble gases have completely filled s and p orbitals, and the f orbitals would be the next in line for additional electrons.


Where are the noble gases located on the periodic table and what does their position reveal about their reactivity?

The noble gases are located in Group 18 of the periodic table (also known as Group 8 or Group 0). Their position reveals that they have a full outer shell of electrons, making them stable and less likely to react with other elements. This stability is why noble gases are often referred to as inert gases.
