What is the number of valency electron in helium?
Helium has two valence electrons.
What is Number of orbitals in helium?
Helium has two electrons, and each electron occupies an orbital. Therefore, in a helium atom, there are two orbitals, one for each electron.
What atom contains 1 electron and 2 protons?
None, for it to be an atom it has the have the same number of electrons and protons. Something with 1 electron and 2 protons would theoretically be a helium ion but helium does not form ions.
What element has 2 electron?
Helium is the element with 2 electrons. It has an atomic number of 2, indicating the number of protons and electrons in its nucleus.
How many electron orbitals does helium have?
How many atoms / electron clouds does helium have ?
What is a possible quantum number set for an electron found in a ground-state helium (He) atom?
A possible quantum number set for an electron in a ground-state helium atom could be n1, l0, m0, s1/2.
When a helium atom loses an electron then what is formed?
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+.
How hydride ion and helium atom have same number of electron?
Both the hydride ion (H-) and helium atom have two electrons. The hydride ion gains an extra electron to achieve an electron configuration similar to helium (1s²), making them both have two electrons overall. Helium naturally has two electrons in its electron configuration.
What is the number of protons neutrons and electrons does helium have?
1 Proton and 1 electron but no neutrons.
What is the number of valence electron for the elements in Group 8A?
Eight, except for helium which has two.
How many electrons shells does a helium atom have?
The electron configuration of helium is 1s2; two electrons on the first (and the single) electron shell.
When helium loses electron it becomes?
When helium loses an electron, it becomes a positively charged helium ion (He+).
