What is the correct name for SrCl2?

They can measure  the amount of energy gained or lost

What are the options? i can you if you give them.

13 protons and 14 neutrons.  this also means that the amount of electrons also is 13 because electrons have the same amount as protons..the atomic number means the amount of protons (which effectively tells you the electrons) the atomic mass, tells you the amount of protons and neutrons in the nucleus.hope this .
