The atomic number of lithium is 3.
Lithium is in the second period and the first group in the Periodic Table of Mendeleev.
Lithium's mass number is 6.941.
Lithium is element #3. That, of course, is the atomic number - the number of protons. The atomic mass will of course depend on the specific isotope. The most common isotope is Lithium-7, that is, atomic mass = 7. Lithium-6 also occurs in nature as a stable isotope.
The number of electrons in each lithium atom is 3.
A neutral lithium atom has 3 electrons, the same as the number of protons, which is the atomic number of lithium. There is no lithium ion with a charge of 7+. If you mean lithium with a mass number of 7, the number of protons is 3 and the number of neutrons is 4.
lithium has 7 isotopes
In a neutral atom of lithium-7, the number of protons equals the number of electrons. The atomic number of lithium is 3, which is the number of protons. So a neutral atom of lithium-7 has 3 protons and 3 electrons.
Lithium has 3 electrons and the Lithium ion has 2.
valency of lithium - 1
Lithium has the atomic number of 3, which means it has 3 protons, and a neutral atom of lithium has 3 electrons.
We can find lithium as a metal element. Atomic number of it is 3.
The group no. of Lithium is 1 and its period number is 2.
Johan August Afrwedson is the man who discovered lithium. He was a Swedish chemist and made his discovery in 1817. Lithium has the symbol Li, and its atomic number is 3.
