the second letter of there element symbol is lower case 'r' and they end with the --ton
I don't know if that helps but looking at the Periodic Table thats all I can see

What is an inert substance?
The "inert" or "noble" gasses are called that because they do not participate in any chemical reactions. They are: Helium, neon, argon, krypton,. xenon, and radon. (Xenon has been known to form compounds with other elements, but only at exceptionally low temperatures.) They are in Column 18 of the WebElements periodic table.
What is the oxidation number for Kr?
The Oxidation number for Kr which is krypton is 2. The Oxidation number for Kr which is krypton is 2. The Oxidation number for Kr which is krypton is 2.
How many electrons does calcium need to gain to become more stable?
Far too many - it needs to gain 16 to get to Krypton which is the next noble gas (energetically impossible) - It is far easier for it to lose 2 (which it does) to get to the Argon structure
What is the charge of a Kr ion?
Krypton is a noble gas. Helium, Neon, Argon, Xenon and Krypton are all notoriously reluctant to form compounds and exist as monatomic atoms. Free krypton would not have a charge.(That, by the way is a standard chemistry groaner: "There's no charge--it's free!"...right up there with "I'm positive I lost my electron.")
Why do the elements in group 16 share similar chemical properties?
2 unpaired valence electrons in their elemental state.
What alkaline earth metal has more protons then argon but less protons then krypton?
This chemical element is calcium (Ca).
What are 4 noble gases?
There are 6 noble gases in all. The are found in group 18. They are Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).
Which element is noble gas?
Group 18 'Noble gases'atom number 2 , Heatom number 10, Neatom number 18, Aratom number 36, Kratom number 54, Xeatom number 86, Rn(atom number 118, not yet known)
How many electrons do the nobles gases have in their outer level?
2 for Helium, 8 for all others; Neon, Argon, Krypton, Xenon, and Radon
What are the 11 gases under room temperature?
The 11 gases are : 1) Hydrogen 2) Oxygen 3) Fluorine 4)Chlorine 5)Helium 6)Nitrogen 7)Neon 8)Argon 9)Krypton 10)Xenon 11)Radon
How many electrons are in the outermost energy level of each noble gas atom?
2 for Helium, 8 for all others; Neon, Argon, Krypton, Xenon, and Radon
What does 2 hydrogen helium 2 bromine nitrogen oxygen fluorine neon chlorine argon krypton xenon and radon combine to make?
Those chemicals do not combine to make any one compound.
Does KR and AR have the same valence electron configuration?
Krypton and argon both have 8 valence electrons. This is true of all noble gases except helium, which has only 2 valence electrons.
Answer key for element crossword puzzles Its a gas?
Its a Gas! Answers. 2 across helium 4 across krypton 6 across neon 7 across argon 9 across oxygen

What is the oxidation number for Kr?
The Oxidation number for Kr which is krypton is 2. The Oxidation number for Kr which is krypton is 2. The Oxidation number for Kr which is krypton is 2.
Why are neon and argon in the 18th column and why is helium also found in this comlumn?
Because Helium (He, 2), Neon (Ne, 10), Argon (Ar, 18), Krypton (Kr, 36), Xenon (Xe, 54) all are Noble Gases which have inert or no-reactive chemical structures. This is due to the "octet" of their electrons.
