What element have the smallest atomic radius?
Atomic Radius gets greater down the periodic table and gets smaller to the right in the periodic table. This means, in order of atomic radius, that the five smallest elements are Helium, Neon, Fluorine, Oxygen, and Hydrogen in that order.

What are the three lightest noble gases?
Technically Helium is classed as a Noble gas and has a MW of 4g/mol.
What element has a mass of less than 30 and is a noble gas?
Neon's mass is the element closest to 30 out of all noble gasses.
What gases are on the periodic table?
in number order it goes hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon, and radon. Hydrogen, nitrogen, oxygen, fluorine, and chlorine are diatomic gases. Helium, neon, argon, krypton, xenon, and radon are monatomic gases.
What element has atomic mass 20 gas?
There are a lot:all 6 noble gases, elements in group 18: He, Ne, Ar, Kr, Xe, Rn,di-atomic gases of elements: N2, O2, F2, Cl2,tri-atomic gas: ozone O3
Helium and neon cant form compounds with fluorine why?
The first Ionization energy of fluorine is less than that of the helium and neon.
Does neon form fluorine?
No because neon is a noble gas so it only forms with helium,Argon and Hydrogen and that doesnt make Fluorine
Is fluorine in the same family as neon?
No- fluorine is a halogen and Neon is an inert or noble gas. Fluorine is one of the most reactive elements of all and Neon is the 2nd most unreactive after Helium. You can not get more different.
What are ten elements?
The first 10 elements, in order of atomic number, are: Hydrogen Helium Lithium Beryllium Boron Carbon Nitrogen Oxygen Fluorine Neon
What are the other gases found in the periodic table?
Mono-atomic gases: Helium, neon, argon, krypton, xenon, and radon. Di-atomic gases: Hydrogen, Nitrogen, Oxygen, Fluorine, Chlorine.
Why does Helium has higher IP than Neon?
because the size of helium is smaller than that of neon.
What element have the smallest atomic radius?
Atomic Radius gets greater down the periodic table and gets smaller to the right in the periodic table. This means, in order of atomic radius, that the five smallest elements are Helium, Neon, Fluorine, Oxygen, and Hydrogen in that order.

What are facts for fluorine?
The salts in Fluorine are called fluorides, and fluorine reacts with all other elements except oxygen, neon, helium, and krypton.
What element has a atomic number lower than alumimum?
There are 12 such elements and they are hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium and magnesium.
What are 3 gasses at room temperature?
Hydrogen, helium, nitrogen, oxygen, fluorine, and neon.
Which gas is monatomic at room temperature and pressure Nitrogen Neon fluorine or Chlorine?
C. Helium is a monoatomic gas at STP.
Can you name a list of 10 NON metals?
Hydrogen, helium, boron, carbon, nitrogen, oxygen, fluorine, neon, phosphorus and sulfur are ten non metals in the order of increasing atomic number.
