how many atoms are there in the helium?
530157
1 He molecule contains only 1 atom(as helium is monoatomic). So, 1 mole He gas contains 2x6. 023x10^23 He atoms.

At this level, it is estimated that the there are between1078 to 1082 atoms in the known, observable universe. In layman's terms, that works out to between ten quadrillion vigintillion and one-hundred thousand quadrillion vigintillion atoms.

A helium atom consists of a nucleus containing two positively charged protons and two neutrons, encircled by two orbiting electrons which carry a negative charge. A hydrogen atom has just one proton and one electron.

He2+ ion has 2 protons. Helium has 2 protons and 2 electrons, When it loses 2 electrons, it becomes Helium ion (also called alpha particle) or He2+.

Helium is also the second simplest of the chemical elements. Its atoms consist of two protons, two neutrons, and two electrons. Only the hydrogen atom is simpler than a helium atom. The hydrogen atom has one proton, one electron, and no neutrons.

If I fill up a balloon with 2 moles of helium atoms, how many helium atoms would be in the balloon? If 1 mole of atoms is 6.02 x 1023 atoms, then 2 moles of atoms would be equal to 1.2 x 1024 atoms.

For helium, it is 4: two protons and two neutrons. For most of the 16 lightest elements (up to oxygen) the number of neutrons is equal to the number of protons.

Avogadro's number states that one mole of any substance contains 6.022 * 1023 number of atoms. That means 1 mol of Helium, 1 mole of Copper, 1 mol of gold, and 1 mol of Aluminum, all contain 6.022 * 1023 number of atoms.

Helium is one of only two natural elements that has never been observed bonding to another element in a compound. ... At normal atmospheric pressure helium does not solidify. At 25 atmospheres of pressure helium is a solid at 0.95 K. As the pressure rises, the temperature at which solid helium exists also rises.

Divide the mass of ordinary matter by the mass of a hydrogen atom (1.45×10^53 kg divided by 1.67×10^−27 kg). The result is approximately 10^80 hydrogen atoms. Originally Answered: How many atoms exist in the universe? Fact - The entire universe is made of atoms .

The He+ ion is just like a hydrogen atom with two units of charge in the nucleus. Since the hydrogenic energy levels depend upon the square of the nuclear charge, the energy of the remaining helium electron should be just 4x(-13.6 eV) = -54.4 eV as observed.

According to the US Department of Energy's Jefferson Lab, the answer is: 133,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. That answer comes from an estimation of the number of atoms in each of Earth's elements, like Iron, Oxygen, Silicon, Magnesium, Sulfur … etc.

Hydrogen has 1 electron in the first shell (so one valence electron). Helium has 2 electrons --- both in the first shell (so two valence electrons).

The Sun contains approximately 1057 atoms of hydrogen. If you multiply the number of atoms per star (1057) times the estimated number of stars in the universe (1023), you get a value of 1080 atoms in the known universe.
