Helium atom is neutral and has no charge. It becomes a positive ion with a charge of +1 when it loses an electron.
The Stock name for the chromium ion with a 3 plus charge is chromium(III). In this naming system, the Roman numeral indicates the oxidation state of the metal ion. Thus, chromium(III) signifies that chromium has lost three electrons to form the ion.
The formula for the manganese (III) ion is Mn3+. The charge on the manganese ion is +3.
the atomic no of calcium is 20 so to reach the nearest noble gas electronic configuration it loses 2 electrons and forms + 2 ion.

NH4 +One plus.
A Lithium ion has a charge of plus one. Hope this helps!
An ion does have a charge. That is what makes it an ion.
The name given to the electrical charge on an ion is a oxidation number. The charge of the ion typically formed by strontium is 2 plus.
Helium atom is neutral and has no charge. It becomes a positive ion with a charge of +1 when it loses an electron.
The bromide ion (Br-) has a charge of -1. In the formation of potassium bromide (KBr), the potassium ion (K+) has a charge of +1, and the bromide ion has a charge of -1 to balance the overall charge of the compound.
Yes - but it is rare - usually has a + 2 charge
Plus 1. Li^+1
An atom of potassium-41 becomes a potassium ion with a plus charge by losing one electron. Potassium-41 has 19 electrons in its neutral state, but when it loses one electron, it becomes a potassium ion (K+) with a plus charge and 18 electrons.
two elements with ions with a 2 plus charge are Sulfurand Oxygen
Ammonim-NH4 There's also Hydronium - H3O
