They do not exist in a stable natural state. They had to be made by man in the same way as many of the Actinides This is wrong. Unlike most actinides, they all exist as stable isotopes and some are reasonably common. The main reason is that they are very chemically similar to one another and thus are hard to isolate as pure elements. this is rite...
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.
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 can you infer about the elements located in the last column of the periodic table?
The elements in the last column of the periodic table are known as the noble gases. They are the least reactive elements because they have a full outer electron shell, making them stable. Noble gases are typically found as single atoms instead of forming compounds with other elements.
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.
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.
Why are noble gases are among the last of the naturally occurring elements to be discovered?
Because they don't react with anything else; when you're looking for reactions, noble gasses are invisible.
What is the placement of the noble gases and why?
The last column of the periodic table of elements

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 can you infer about the elements located in the last column of the periodic table?
The elements in the last column of the periodic table are known as the noble gases. They are the least reactive elements because they have a full outer electron shell, making them stable. Noble gases are typically found as single atoms instead of forming compounds with other elements.
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.
What is the last column of the periodic table called?
The last column of the periodic table is called the noble gases or Group 18 elements. These elements are known for their stable and non-reactive properties due to having a full outer shell of electrons.
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.
What is the Noble gases names?
The noble gasses are all elements in the last group in the Periodic Table, starting w/ helium ending w/ radon
