2.7 Ions

What differentiates one atom from another is the number of protons it possesses. When the number of protons are varied, the identity of the atom is changed. Atoms are neutral species, meaning that they have the same number of protons and electrons. When the number of electrons is varied atoms form charged particles called ions. An ion with a positive charge is called a cation and an ion with a negative charge is an anion.

    The video for this part of the lecture is incorrect, the video for avogadro’s number is posted instead of the one on ions.
