The Paschen series of helium ion refers to transitions ending at the n=3 energy level. The series limit for the Paschen series of helium ion occurs when an electron transitions from a higher energy level to the n=3 energy level. This results in the emission of photons in the infrared region of the electromagnetic spectrum.

What ions have the same electron configuration as helium?
Lithium ion (Li+) and beryllium ion (Be2+) have the same electron configuration as helium because they both have filled electron shells.
Is helium a polyatomic ion?
No, helium is a noble gas and exists as a monatomic element, consisting of single atoms. Polyatomic ions are made up of multiple atoms bonded together with an overall charge.
What is the formula of the hydride formed by helium?
The formula of the hydride formed by helium is HeH+. It's a cationic species known as the helium hydride ion, which is formed when helium reacts with hydrogen ions in very low-temperature environments such as interstellar space.
Which ion has the same electron configuration as an atom of He?
The He+ ion (helium ion) has the same electron configuration as an atom of helium (He) because it has lost one electron, making it a 1+ ion. Both the helium atom and He+ ion have a total of 2 electrons arranged in the 1s orbital.
What element that forms an ion has the highest electronegativity?
Fluorine is the element with the highest electronegativity, making it more likely to form an ion.
What is the ion charge of a helium atom Is it plus 1?
Helium atom is neutral and has no charge. It becomes a positive ion with a charge of +1 when it loses an electron.
Is helium an isotope atom or ion?
Helium is a neutral atom that has several isotopes and can become an ion.
Is the helium ion positive or negative?
Helium ion is positive, assuming it has lost an electron. Helium typically has 2 electrons, so an ion of helium with 1 electron removed would have a net positive charge.
Why is o6 a helium like ion?
Helium has two valence electrons. O6+ ion (a hypothetical ion) will also have 2 valence electrons.
If a helium ion is emmited during the disintegration of a nucleus what kind of decay is this called?
Nuclear emission of a helium ion is called alpha decay.
Is there a limit to the negative charge that can occur on an ion?
Yes, there is a limit to negative charge that can occur on an ion.
What is helium's type of ion?
Helium is chemically inert and does not form any type of ions.
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+.
When helium loses electron it becomes?
When helium loses an electron, it becomes a positively charged helium ion (He+).
What is isoelectronic with helium?
Atoms or ions that have the same number of electrons as helium (2 electrons) are considered isoelectronic with helium. Examples of species that are isoelectronic with helium include H+, Li+, Be2+, and B3+.
What ions have the same electron configuration as helium?
Lithium ion (Li+) and beryllium ion (Be2+) have the same electron configuration as helium because they both have filled electron shells.
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 (1sĀ²), making them both have two electrons overall. Helium naturally has two electrons in its electron configuration.
