How many neutrons in a lithium atom
Did you know?
WebBeryllium is a chemical element with atomic number 4 which means there are 4 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. WebFor example, a lithium atom (Z=3, A=7 amu) contains three protons (found from Z), three electrons (as the number of protons is equal to the number of electrons in an atom), and four neutrons (7 – 3 = 4). Isotopes Isotopes are various forms of an element that have the same number of protons, but a different number of neutrons. Learning Objectives
