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 smaller atomic mass than krypton?
Argon (Ar) has a smaller atomic mass than krypton (Kr). Krypton has an atomic mass of about 83.80 u, while argon has an atomic mass of approximately 39.95 u. Other elements with smaller atomic masses than krypton include neon (Ne) and helium (He).
Neutral atoms of neon atomic number of 10 have the same number of electrons as each what except?
Neutral atoms of neon have the same number of electrons as atoms of fluorine, magnesium, and sodium, excluding helium atoms.
What element has a mass of less than 30 and is a noble gas?
The element with a mass of less than 30 and is a noble gas is Neon (Ne). Neon has an atomic mass of around 20.18 and is a colorless, odorless gas commonly used in neon signs due to its bright red-orange glow when electrified.
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 gas will diffuse faster He or Ne?
Helium (He) will diffuse faster than Neon (Ne) because helium has a lower atomic mass and smaller atomic size, making it lighter and easier to move through a medium.
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.
Helium and neon cant form compounds with fluorine why?
Helium and neon are noble gases, which have full valence shells of electrons and are highly stable. They do not readily form compounds with other elements, including fluorine, because they have little tendency to gain or lose electrons to form chemical bonds. This makes them unreactive and inert.
What are 3 gasses at room temperature?
Hydrogen, helium, nitrogen, oxygen, fluorine, and neon.
What are the three lightest noble gases?
Technically Helium is classed as a Noble gas and has a MW of 4g/mol.
What has the smallest atomic radius out of hydrogen sodium and lithium?
Helium has the smallest atomic radius out of hydrogen, sodium, and lithium. This is because helium has a full electron shell, leading to a smaller effective nuclear charge that pulls the electrons closer to the nucleus, resulting in a smaller atomic radius.
What element has a smaller atomic mass than krypton?
Argon (Ar) has a smaller atomic mass than krypton (Kr). Krypton has an atomic mass of about 83.80 u, while argon has an atomic mass of approximately 39.95 u. Other elements with smaller atomic masses than krypton include neon (Ne) and helium (He).
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.
