What else can I help you with?
Which has smaller atomic size helium or fluorine or neon?
He has the smaller atomic size. Fluorine has the larger atomic size from these 3. He is a noble gas.
What is the atomic number for helium?
The atomic number of Helium is 2.
What is the atomic radius of helium and how does it compare to other elements in the periodic table?
The atomic radius of helium is about 31 picometers. Helium has one of the smallest atomic radii among all the elements in the periodic table due to its small size and high nuclear charge.
What is helium's atomic?
Helium's atomic number is 2 and its atomic mass is 4
What is atomic weight of helium?
4.002602 g/mol
Name the noble gas withe the smallest atomic number?
The noble gas with the smallest atomic number is helium, with an atomic number of 2.
What happens to the size of the atomic radius as you go down the noble gas family?
The atomic radius increase down, from helium to radon.
What is the size of the atom in helium?
The size of an atom is typically measured in terms of its atomic radius, which for helium is approximately 31 picometers (pm), or 0.31 angstroms. This corresponds to the distance from the nucleus to the outermost electron cloud in a helium atom.
What is the atomic number of this element helium?
The atomic number of helium is 2. It has 2 protons in its nucleus, which defines its atomic number.
How much does atomic mass helium have?
It's just 4.002602 amu
How many atomic number are in helium?
The atomic number of the element Helium is two.
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.
