(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).

2015-06-01T18:03:41-04:00. The answer is (2). The Lithium has 3 protons and 4 neutrons. For every neutral atom, it will have the same number of protons and electrons. Because the proton has one positive charge and electron has one negative charge and neutron does not have charge. Comments
In a sample of 400 Lithium atoms, it is found that 30 atoms are Lithium-6 (6.015 g/mol) and 370 atoms are Lithium-7 (7.016 g/mol). Calculate the average atomic mass of Lithium and enter the number below. Use two decimal places.n a sample of 400 Lithium atoms, it is found that 30 atoms are Lithium-6 (6.015 g/mol) and 370 atoms are Lithium-7 (7.016 g/mol).
