Answer from: taterbuglee2003

An Atom is electrically neutral with a charge equal to 0, because it have the same number of protons and electrons.
In ion is an atom who lose or gain electrons. When it lose an electron, the number of protons will be higher than then number of electrons in an normal atom, and will be called positive ion or cation.
Example: The Aluminium lose 3 electrons. So the ion of Al will be $Al^{3+}$ , and its charge is 3+
Ionization equation: $Al -----\ \textgreater \ Al^{3+} + 3^{e-}$
And When an ion gain electrons, the number of electrons will be higher than the number of protons in an normal atom, and will be called negative ion, or Anion..
Example: the Chloride gain 1 electron. So the ion of Cl is $Cl^{1-}$ , and its charge is 1-
Ionization equation: $Cl + 1^{e-} ----\ \textgreater \ Cl^{1-}$

HOPE THIS HELPS :D

Answer from: MaddieXMooo990

An atom or molecule with a net electric charge due to the loss or gain of one or two electrons is known as ion .
ions are of two types
1. cations ( positive ion )
2. anion (negative ion )
for e.g Al³+

a. by the combination of an unlimited number of elements

Answer from: Quest

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
