A possible quantum number set for an electron in a ground-state helium atom could be n1, l0, m0, s1/2.
No, it is not possible to manufacture helium. Helium is a naturally occurring element that is produced through the process of nuclear fusion in stars.
The ionisation energy depends on the orbital from which the electron is removed and also the distance of the orbital from the nucleus. In the case of Helium, the electron is removed from 1s orbital whereas in the case of argon it is from 3p orbital. As 1s is closer to the nucleus, the force of attraction experience by these electrons is higher and hence helium will have higher 1st ionisation energy.
Yes, it is possible to artificially produce helium through nuclear reactions, such as in nuclear reactors or particle accelerators.
Helium has a larger ionization energy compared to lithium. This is because helium has a full valence shell, making it more difficult to remove an electron compared to lithium, which has only one electron in its outer shell.
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.
The quantum number set of the ground-state electron in helium, but not in hydrogen, is (1s^2) or (n=1, l=0, ml=0, ms=0). It indicates that the electron occupies the 1s orbital, which has a principal quantum number (n) of 1, an orbital angular momentum quantum number (l) of 0, a magnetic quantum number (ml) of 0, and a spin quantum number (ms) of 0.
How many atoms / electron clouds does helium have ?
When a helium atom loses an electron, it forms a helium ion which is positively charged because it has one less electron than protons. This helium ion is written as He+.
When helium loses an electron, it becomes a positively charged helium ion (He+).
The electron configuration of helium is 1s2; two electrons on the first (and the single) electron shell.
Helium has no electron affinity.
Electron configuration of helium: 1s2
n = 1 l = 0 m = 0 s = +1/2 and s = -1/2
There are several different quantum numbers for a given atom (principle quantum number, the angular quantum number, the magnetic quantum number, the spin quantum number, etc) .I assume you are looking for the Principle Quantum number, n, which is equal to the row (period) in the period table in which the element is situated.For helium, the principle quantum number is 1.i.e. n = 1As another example; the principle quantum number for potassium (K), n = 4.
Helium has two valence electrons.
Helium has two electrons which completely fills the first principal quantum level.
Helium has two electrons, and each electron occupies an orbital. Therefore, in a helium atom, there are two orbitals, one for each electron.
