Any time there is an imbalance of charges in an atom, that is, if the number of protons in its nucleus doesn't match the number of electrons in orbit around it, then that atom has an overall charge, and it is an ion. Note that ions can be positively or negatively charged, and the charges will (naturally) be integers, as charges here go up or down by or in increments of one electron. To convert a neutral atom into an ion, you'll either give it one or more electrons, or take one or more electrons from it. It will then have an overall charge of -1, -2, -3, etc., or +1, +2, +3, etc., respectively. energy is required (heat of sublimation and ionization potential), to remove the electrons from atoms and in most of the cases energy is released (dissociation energy which is absorbed and electron affinity which is released) when electron is absorbed in an atom.

What conclusions can we make about the size of cations neutral atoms and anions?
Cations are smaller then neutral atoms and anions are larger.
What type of bond holds sodium and cholride atoms together when sodium atoms interact with chlorine atoms?
When sodium atoms and chlorine atoms interact, the sodium atoms are converted to positively charged cations and the chlorine atoms are converted to negatively charged anions. The cations and anions to which the atoms have been converted are held together by mutual electrostatic charge attractions.
True or false Metals are made up of cations not neutral atoms?
false
What type of atom do cations represent?
Cations are neutral atoms that have lost an electron or electron(s). They are positively charged. They are generally metals.
Cations are formed when neutral atoms lose?
Yes, they loose electrons : e-

Cations are formed by?
cations are positively charged ions formed by loss of electrons from the neutral atoms having 1,2,3 electrons in the outermost orbit

What is the charge of each atom before and after forming ionic bond?
Before the forming of the bond atoms are neutral; after the forming of the bond atoms become cations or anions.
What is the charge of each atom before forming the ionic bond?
Before the forming of the bond atoms are neutral; after the forming of the bond atoms become cations or anions.
What is the different and what is the same between an atom and an element?
Atom is neutral while cation is positively charged so cations have less electrons than corresponding atoms, another difference is that cations are always smaller in size as compare to their respective atoms.
What happened when you change a neutral atom into a positive charged atom?
Positively charged cations are formed when atoms lose the valence electrons.
Where is the excess copper from after adding zinc to copper sulfate?
The "excess" metallic copper produced by adding zinc metal to a copper sulfate solution comes from exchanging zinc atoms from the metal for copper atoms from the copper sulfate solution. During the reaction, the zinc atoms are ionized to cations and the copper cations from the solution are reduced to neutral atoms.
What does it mean when chemists say that a reactant is reduced?
When a reactant is reduced, it gains electrons. Thus, metal cations can be reduced to neutral metal atoms.
