(For example: Arun Paul MSW, MPHIL). Documentation of academic and professional credentials usually consists of a printed, formal document. The issuing institution often maintains a record of the credential as well. Academic credentials are normally valid for the lifetime of the person to whom they are issued.For example: Arun Paul MSW, MPHIL).

Best Answer: you are correct that protons determine the element's identity. Mg-24 and Mg-26 both have 12 protons but the 24 and 26 are the number of protons plus neutrons. Mg-24 has 12 protons and 12 neutrons, while Mg-26 has 12 protons and 14 neutrons. elements that have the same number of protons but different numbers of neutrons are called isotopes. Mg will always have 12 protons...if you change the number of protons, you change the element. Mg-24 and Mg-26 are two different isotopes of magnesium.
