Can an ion lose all of its electrons?And what is it called?

Just answered it in your other post, but perhaps this: Oxidation-reduction is a chemical reaction in which an atom or ion loses electrons to another atom or ion.

The first part of your question is not quite accurate. An ion is an atom. Normally, atoms are neutral; that is, they carry no charge.\n\nSo let's imagine you have a hydrogen atom with its single electron. If the hydrogen lost the electron, it would be a positively charged hydrogen ion. If the hydrogen gained an electron, it would be a negatively charged hydrogen ion. It would still be the same size as it was before, but the electrical charge would be different.

when an atom loses an electon from its outermost shell then it forms an electropositive ion while when an atom gains an electron it forms an electronegative elctron.\n\nfor e.g. during the formation of nacl na atom loses an elcron to the cl atom to form a +ve ionwhile the cl atom which gains that electon forms a -ve ion.

You should recognize that, when they combine with nonmetals, metals tend to LOSE electrons and form POSITIVE ions. Nonmetals, on the other hand, tend to GAIN electrons and form NEGATIVE ions.\n\nGet an "A".

Although atoms contain both positively and negatively charged particles, they contain the charges in equal portions. That is, an atom has the same number of electrons (negatively charged) and protons (positively charged), so the charges cancel each other out. \n\n\nHowever, an atom can gain or lose electrons resulting in a charged atom known as an ion.

Some atoms do not loose their electrons easily.  These can either share electrons (like carbon usually does) or snatch electrons from other atoms to become negative ions (like Fluorine does).  Most metallic elements easily loose electrons to become positive ions (like sodium Na - e- = Na+).

For element X the amount of energy required to remove one of the the outermost electrons to make the ion X+ (hence the name Ionisation)

cation, a negatively charged ion would be an anion...

Not much of an atom if it can't hold onto its electron!

electron gain is considered as oxidation and electron lose is taken as reduction. and that element that give electron to other element so that it can oxidise is called as oxidizing agent\n\neg :- al^+3 -- reducing agent\n\nso here zn is getting oxidized  and ni is being redused\nNi (aq) is the redusing agent\nany doubts . mail me piyush.khadgi@gmail.com

positive ions are formed by removing electrons from the atoms and hence the ionic radius for positive ion is always less than that of atomic radius

yes there is an effect called tunnel effect. it is related to quantum mechanics.When a particle like elctron does not have enough energy to come out of a potential barrier or well, tunnel effect comes into play.

You cannot have one without the other.  If there are cations present, there will be an equally charged pile of anions there with it.  The charge on any system is always neutral (or very close - it may have some electrical potential but relatively speaking, it's very low).

They would lose electrons.  metals lose electrons to obtain there octet.  \n\nNa, K would lose 1 electron\n\nMg and Ca would lose 2.\n\n\nwhoever said Ca would gain an electron is an idiot

Atoms form bonds to get to a stable form. All atoms (besides noble gases) want to get a full shell of valence (outside) electrons. To get this full shell, they have to share electrons with others. This is called a covalent bond. \n\nOr, in the case of ionic bonds, a molecule that has extra electrons simply gives electrons to another molecule who wants them. These molecules become positive and negatively charged, and stick together because of magnetic attractions.

Individual atoms in the battery are made up of a nucleus (protons and neutrons) surrounded by electrons.  The chemical reactions in batteries cause these atoms to gain or lose electrons so that electrons become free to be conducted to another atom, or conversely the atom that has lost an electron becomes open to accepting an electron because it has a hole where an electron used to be. This flow of electrons (or holes) are what is called electrical current. The potential between atoms is measured in volts. The flow of electrons is measured in amperes (or amps).

I'll do one for you and then you can try the rest.\n\nMagnesium has 12 electrons, so follow your filling order. Each s orbital holds to electrons and each p orbital holds 6, so its:\n\n1s2 2s2 2p6 3s2\n\nIt has 2 electrons in its outer shell so to have a full outer shell it will lose 2 therefore the common ion It forms is Mg2+
