helium as it contains 2 protons, while hydrogen only contains 1. Additionally, the orbit of the 2 electrons in a neutral helium atom would also be larger than the orbit of the single electron in hydrogen.

∙ 12y agoNeon is larger because it has more protons, electrons, and neutrons. Look at the element's Atomic Mass for an idea of its size.

∙ 11y agoYes neon is larger than helium. Down a group, atomic size increases.

∙ 11y agoThe hydrogen ion, H+, is very tiny. It is just a proton (at least when it is the usual hydrogen isotope). It has no electron shell left. Hence, it is smaller than helium.

What is the smallest atom?
Hydrogen is the smallest atom by mass. Helium, neon, fluorine and oxygen are smaller in size. Many calculations put the helium as the smallest atom. But a few other calculations put neon as the smallest atom!
Which has greater number of atoms a gram of helium or a gram of neon?
Neon is larger because it has more protons, electrons, and neutrons. Look at the element's Atomic Mass for an idea of its size.
What are the differences between neon and helium?
Neon has 8 more protons and 8 more electrons than helium. It's heavier, but still lighter than air.
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.
At STP which gas will diffuse more readily than Ne He Ar Kr or Xe?
Helium is lighter than neon and will diffuse faster than neon.
Why does Helium has higher IP than Neon?
because the size of helium is smaller than that of neon.
Does magnesium have a smaller radius than helium?
Atoms do not have a radius. A helium atom has a nucleus composed of at least two protons and maybe one or two neutrons. A magnesium atom nucleus (and every other atom on the periodic table other than hydrogen) is BIGGER than a helium nucleus. So if you look at it that way...magnesium is larger than helium

Helium and neon cant form compounds with fluorine why?
The first Ionization energy of fluorine is less than that of the helium and neon.
Which has greater number of atoms a gram of helium or a gram of neon?
Neon is larger because it has more protons, electrons, and neutrons. Look at the element's Atomic Mass for an idea of its size.
What are the differences between neon and helium?
Neon has 8 more protons and 8 more electrons than helium. It's heavier, but still lighter than air.
Which is better neon gas or xenon gas?
Depends on the purpose. But if you combine neon with helium, and obtain a helium-neon laser, you can see that it is much smaller than a xenon laser.
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.
At STP which gas will diffuse more readily than Ne He Ar Kr or Xe?
Helium is lighter than neon and will diffuse faster than neon.
What is the diameter of the helium atom?
The nucleus of a Helium atom contains two protons and two neutrons, protons and neutrons are measured in Daltons, and a Helium atom is about 4 Daltons
How is helium atom different from a hydrogen atom?
Helium has a nuclear charge of +2 and 2 electrons in a 1s orbital. Hydrogen has a nuclear charge of +1 and just one electron in a 1s orbital. The extra charge on the nuclees means that the electrons in He are more tightly bound than in hydrogen thuis reflected in the ionization energy of 2372 kJ/mol for He and about 1312 kJ/mol for hydrogen. For helium t the "outer shell" is full, a "stable " configuration.
Is a lead atom heavier than a helium atom?
Yes; helium has an atomic weight of 4.00260, and lead has an atomic weight of 207.2.
