Web21 feb. 2024 · Lithium is a chemical element with the symbol Li and atomic number 3. It is a soft, silver-white metal that belongs to the alkali metal group of elements. Lithium has the lowest density of all metals and is the lightest solid element.Lithium's low reactivity is due to the shielding effect of its two electrons. Lithium shows a metallic luster when it is in open … WebThe number of neutrons in an element is obtained from the difference between the number of atomic masses and the number of atoms. That is, neutron number (n) = atomic mass number (A) – atomic number (Z) We know that the atomic number of lithium is 3 and the atomic mass number is about 7 (6.938). Neutron (n) = 7 – 3 = 4. bisley tambour units

WebLithium was used during the 19th century to treat gout. Lithium salts such as lithium carbonate (Li2CO3), lithium citrate, and lithium orotate are mood stabilizers. They are used in the treatment of bipolar disorder, since unlike most other mood altering drugs, they counteract both mania and depression. WebIsotope notation, also known as nuclear notation, is important because it allows us to use a visual symbol to easily determine an isotope's mass number, atomic number, and to determine the number of neutrons and protons in the nucleus without having to use a lot of words. Additionally, N = A −Z. Example 1: What is the isotopic notation for ... WebSince lithium lithium 's atomic number is 3 3, Li Li has 3 3 protons. 3 3 protons. Fill in the known values where N N represents the number of neutrons. 7 = 3+ N 7 = 3 + N. Rewrite the equation as 3+N = 7 3 + N = 7. 3+N = 7 3 + N = 7.
