(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
Lithium has a total of four neutrons. The element also has an atomic number of 3 and an atomic weight of 6.94. It is found in the alkali metal group on the periodic table and has the chemical symbol of Li. Lithium is a silver-colored element that also includes three protons and three electrons. The number of protons and electrons in any given element is the same as its atomic number. The number of neutrons in an element can be found by subtracting the number of protons from the rounded atomic mass of the element. For lithium, the rounded atomic mass is seven, and seven minus three equals four neutrons. Learn more about Chemistry
