An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
The Alkali Family
Sodium twins, the time has come for both of you to find an element to bond with
No, you must bond or you will be unstable for the rest of your life. You have one valence electron which needs to react with another element.
But we want to stay here, in the Alkali Metal family forever
Sodie 1, you will bond ionically with Chlorine.
Sodie 2,you will bond covalently with hydroxide (OH)
Sodie 1's Bonding Ceremony
Hello Chlorine, I am ready to give you one of my electrons to become a positively charged cation
Hello Sodium, I am ready to accept your electron to become a negatively charged anion.
Sodie 2's Bonding Ceremony
Hello hydroxide, I am ready to give you one of my electrons to become a positively charged cation
Sodium, we are hydrogen and oxygen, joined together by a covalent bond.
We are 2 non-metals who share electrons.
We are ready to accept your electron to become a negatively charged anion
