A charged atom or group of … WebLithium always has three protons, and its atomic number is 3, which is determined by the number of protons (or by the nucleus’ charge if you want to be more technical). As a result, a neutral-charged lithium atom will also have three electrons. Li7, which has four neutrons, makes up 92.5% of naturally occurringlithium atoms.
WebA lithium-7 atom contains three protons, four neutrons, and three electrons. Because of its nuclear properties, lithium-7 is less common than helium, carbon, nitrogen, or oxygen in the Universe, even though the latter three all have heavier nuclei . 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
