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 else can I help you with?
Which gas is not found in the same period as lithium?
Several elemental gases are not in the same period as lithium. These are: hydrogen helium chlorine argon bromine krypton xenon radon
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.")
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.
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.
Will potassium share more properties with calcium or sodium?
Potassium will share more properties with sodium as they both belong to the same group (Group 1) in the periodic table. They both have similar chemical reactivity and form similar types of compounds. Calcium, on the other hand, belongs to Group 2 and exhibits different properties compared to potassium.
What alkaline earth metal has more protons then argon but less protons then krypton?
This chemical element is calcium (Ca).
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 4 noble gases?
The four noble gases are helium, neon, argon, and krypton. These gases are known for their low reactivity and full outer electron shells, making them stable and unreactive under normal conditions. They are commonly used in lighting, welding, and other applications where a non-reactive atmosphere is needed.
Which gas is not found in the same period as lithium?
Several elemental gases are not in the same period as lithium. These are: hydrogen helium chlorine argon bromine krypton xenon 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
Which noble gas is isoelectronic with a calcium ion?
(Ar) Argon because Ca ion is Ca2+ so it give away 2 electrons
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.
Is helium and argon the same?
No, helium and argon are not the same. They are two different elements on the periodic table with different properties. Helium is a noble gas with the atomic number 2, while argon is also a noble gas but with the atomic number 18.
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
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.
