IONS. red and green are opposites. assume red and green cancel each other. net color = neutral. take away one red. take away one red. net color = 1 green. take away two red. take away two red. net color = 2 green. net color = neutral. net color = 2 red. in this arrangement ….
E N D
assume red and green cancel each other net color = neutral
take away one red net color = 1 green
take away two red net color = 2 green
green is trapped inside. Only red balls can be added or taken away…
In order to understand what ions are, we need to know that…
+ + + + + the particles that make up atoms have either positive or negative charge
+ + + + + positive and negative are opposites they cancel each other out
+ + + + + net charge = zero
+ the positive (+) particle is called a proton
+ + + + + in an atom, protons ( ) are in the center and electrons ( ) are on the outside +
+ + + + + only electrons ( ) can be added or taken away
+ + + + + this is an atom with 5 electrons and 5 protons
+ + + + + the atom is neutral net charge = zero
+ + + + + 5 (-) and 5 (+) = zero charge (neutral)
+ + + + +
+ + + + +
+ + + + + charge = ?
+ + + + + charge = 1- (one minus)
+ + + + +
+ + + + +
+ + + + charge = ?
+ + + + + 2+ (two plus)
WHEN REMOVING ELECTRONS THE RESULTING CHARGE IS POSITIVE
WHEN REMOVING ELECTRONS THE RESULTING CHARGE IS POSITIVE 1+ neutral
WHEN ADDING ELECTRONS THE RESULTING CHARGE IS NEGATIVE
