(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).

You define charge as the deficiency of electron in an atom. Lithium has 3 electrons, 2 in inner shell and 1 in outer shell. If lithium loses one electron then it is said to have a charge of +1 if 2 electrons lost then the charge would be +2 and if all the electrons are lost then charge would be +3. It is easier for lithium to lose one electron (outermost one) because of some factors (ionisation enthalpy, penetration power, outermost shell complete* etc).
