All elements have electrons, when the amount of electrons they have changes they are called ions. They only element that forms an ion with no electrons is Hydrogen (H). To learn more about electrons and ions you should inquire about electron configuration.
as such there is no element in nature which does not have electron.
The hydrogen (positive) ion, H+, has no electrons.
noble gases
The chloride ion has 18 electrons.
There are 10 electrons in an Mg2+ ion.
Ion
There are 8 protons and 10 electrons in an oxide ion.
Most probably 10 electrons as a phosphide ion with 3-charge has 8 valence electrons.
an ion
Potassium ion has 18 electrons.
There are 18 electrons in a chloride ion.
a cuprous ion has 28 electrons.
The ion Fr+ has 86 electrons.
The chloride ion has 18 electrons.
There are 10 electrons in an Mg2+ ion.
electrons are negatively charged, so losing electrons will result in a cation, or a positive ion.
The H+ ion has no electrons.
Ion
If the ion is the most common anion of fluorine, a fluoride ion, it contains 10 electrons.
An ion is a electrically charged atom (negative ion) has more electrons that protons and positive ion has more protons that electrons)
