Because the periodic table goes by atomic number, and they all happen to line up at the end of the table.
In more detail, the chemical properties and electron configurations of the elements determine the arrangement. The noble gasses all have a full valence shell, so they are placed at the end of the table to indicate.
What else can I help you with?
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.
Are the noble gases stable or unstable?
All noble gases are stable except the last one, i.e. Radon(Rn)
Which side of the periodic table contains noble gases?
right side, last group (or last column). Noble gases are group 18 elements.
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).
What are the nonmetals in nobel gases?
There are no metals in noble gases.All are gases in noble gases.
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.
What are the noble gases on the periodic table?
The very last row on the right
What is the placement of the noble gases and why?
The last column of the periodic table of elements
Are the noble gases stable or unstable?
All noble gases are stable except the last one, i.e. Radon(Rn)
Which side of the periodic table contains noble gases?
right side, last group (or last column). Noble gases are group 18 elements.
What section are noble gases in on the periodic table?
The very last row on the right
Why do you think the noble gases were among the last of the naturally occurring elements to be dicovered?
Noble gases are chemically inert, they do not form compounds. They are found in trace amounts and hence difficult to be identified.
Why do you think the noble gases were among the last of the natural occurring elements to be discovered?
Noble gases exist in nature in very low concentration and are very unreactive. These prevented their discovery earlier.
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).
What is the last row of each elemint in a peridoc table called?
inert or noble gases
How active is noble gases?
Noble gases are chemically inert.
How are noble gases different than noble gases?
it's not
