How to name an ionic compound
What is -Separate into cation and anion -cation is named first using element name -anion is named second. Use the root of element and add -ide at the end
300
The concepts of excited and ground state of electrons in the atom
-when an electron gains an amount of energy equivalent to the energy difference, it moves from its ground state to a higher energy level -when electron moves to a lower energy level, it releases an amount of energy equal to the energy difference in these levels as electromagnetic radiation
