When you say Ion you have to specify whether its negative or positive and the number associated with it. For example: if its Li 3- it means it has 3 more electrons then regular Lithium (which has 3 electrons) that makes it 6 electrons and 3 protons (this nr doesnt change) for Li 3-. Obviously calculations vary depending on the type of ion.
Scandium typically has 21 electrons in a neutral atom. In an Sc3+ ion, it loses 3 electrons, so the ion would have 18 electrons.
There are less electrons than protons in a positive ion. More information is needed to determine the exact number. Here is an example: How many electrons are in a carbon ion with a positive charge of positive 2e? There are 6 protons in carbon (since it is element number 6). Since it has a charge of +2, there will be 2 less electrons than protons, so the number of electrons would be 4.
an ion
The C4- ion has a total of 18 electrons. Carbon normally has 6 electrons, but the negative charge of -4 means that there are 4 extra electrons added to the ion.
Li+ ion has only 2 electrons in its only shell and they could be considered as both core and valence electrons.

There are 3 protons and 2 electrons present in a lithium ion.
All lithium atoms and ions have three protons. The lithium ion has a charge of +1, meaning there is one less electron than protons, two.
Lithium ion is Li^1+ and the number of protons is 3 and the number of electrons is 2.
Lithium (Li) has an atomic number of 3, meaning it has 3 electrons. When an atom loses electrons, it forms a positive ion, so for Li to become a Li+ ion, it must lose 1 electron, leaving it with 2 electrons.
Lithium loses one electron to become the cation Li+.
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+.
There are 18 electrons in a chloride ion.
The ion Fr+ has 86 electrons.
a cuprous ion has 28 electrons.
This alkali metal is lithium (Li).
