Any of the noble gases. Argon an Helium are the two closest in the periodic table and would be extremely similar. Neon is a noble gas (chemically inert). The noble gases are helium, neon, argon, krypton, xenon, and radon. The best way to find elements that are similar is to look at a periodic table of elements. The elements with similar characteristics are grouped and listed in vertical columns (above or below one another).
Argon is a nobel gas. Nobel gases are located in Group 18. Elements have similar properties within the same group. Argon has similar properties to Helium, Neon, Krypton, Xenon, and Radon.
no because density increases down a group
Argon is in the same family as Neon, as they belong to the noble gases or Group 18 elements on the periodic table.
They are the noble gasses helium, neon, argon, krypton, xenon and radon and also less importantly the highly unstable and virtually non existent in nature: ununoctium. These noble gases have stable electronic configuration (they have completely filled valence orbitals / energy levels) and are chemically inert under STP. Hence they are considered to be inert gases.
Helium and krypton are different in reactivities. Helium is chemically inert, meaning it does not readily react with other elements. Krypton, on the other hand, is slightly reactive and can form compounds with more reactive elements under certain conditions.
Helium, argon, krypton, xenon, radon, and uuo
all noble gases such as helium, argon, krypton, xenon, radon
Other elements in the same group will have similar chemical and physical properties to krypton. Krypton (Kr) is in group 18 of the periodic table, called the noble gases. Other noble gases, such as neon (Ne) or argon (Ar), will have similar chemical and physical properties to krypton.
Helium is more unreactive than krypton. Helium is a noble gas located in the first group of the periodic table, making it the least reactive element. Krypton, also a noble gas, is located in the same group but is slightly more reactive than helium.
Argon is similar to helium and neon as it belongs to the same group of noble gases. Like helium and neon, argon is colorless, odorless, and inert under normal conditions.
Helium belongs to the 18th group which is known as noble gases/rare gases/zero group elements/inert gases.The other member areNeon(Ne)Argon(Ar)Krypton(Kr)Xenon(Xe)Radon(Rn)There is a vacant space at 118 i.e.marked as Un-Un Octium (Uuo) in the periodic table. If any element occurs that place, then it will be a rare gas.
All of the noble gases have similar chemical properties; helium, neon, argon, krypton, xenon, and radon.
Krypton is more similar.
Elements in the same column as helium on the periodic table (Group 18, also known as the noble gases) have similar chemical properties. These elements include neon, argon, krypton, xenon, and radon. Like helium, these elements are inert gases that are colorless, odorless, and have low reactivity.
