The loss of an electron from a neutral helium atom results in

Question

BlackTom AI · Accepted Answer

The question asks about the product when a neutral helium atom loses one electron.

With neutral helium, the atom has 2 protons and 2 electrons, making it electrically neutral overall. When one electron is removed, the atom retains one electron but now has a net positive charge of +1, resulting in a singly ionized helium atom. A commonly used label for this species is He+, or helium ion with a single positive charge.

If we consider possible answer choices, typical correct phrasing would include terms like 'singly ionized helium,' 'He+,' or 'helium ion (charge +1).'

Incorrect options would usually include:
- 'neutral helium' because removing an electron cannot leave the atom neutral.
- 'doubly ionized helium' or 'He2+' because that would require removing both electrons.
- 'helium anion' or any option implying a gain of electrons, which contradicts the given loss.
- broad statements like 'a positive ion' without specifying the charge state could be partially correct but lack specificity; the precise description here is a +1 charge species.

In summary, losing one electron from neutral helium yields a singly charged helium ion, commonly denoted as He+.
