Electrical Charges

Positive Charge - A positive charge is obtained by a body when it loses electrons or gains a proton . The positively charged ion is also known as cation . The process of losing electrons is also known as oxidation . Elements to the left of the periodic table are electro-positive and lose electrons easily to become cation . When in the state of cation . Its ion's atomic radius decreases . Examples of such highly electro-positive elements are Lithium , Sodium , Potassium , Rubidium , Cesium . Even gaining proton makes atoms or molecules positively charged . Like when acids are added to water . Water gains a H+ ions or basically a proton to become a cation .
Negative Charge - A negative charged is obtained by a body when it gains electrons or loses protons . The negatively charged ion is also known as anion . The process of gaining electrons is also known as reduction . Elements to the right of the periodic table are electro-negative and tend to pull electrons towards itself . When they are in the state of anion , their atomic size generally increases . Examples of such highly electro-negative elements include fluorine , chlorine , oxygen , nitrogen etc. Even when they lose protons like in Acids with a hydrogen atom and an electro-negative atom , when the bond breaks , the hydrogen is released but then the electro-negative atom pulls the electron from hydrogen and becomes a anion and the proton is given away .

Common properties : Both positive and negatively charged body interact with magnetism . When these charged particles are moved , they tend to create a magnetic field , when entering an external magnetic field , they both experience a  force , if entering perpendicularly to the magnetic field , they start revolving in a circle . The state of these ions is plasma , they show conductive properties just like metals as they carry charge . These ions also glow when electricity is passed through them .
