WebLawrencium is a classified actinide element and its symbol is ‘Lr’. Lawrencium is the 103rd element of the periodic table so its atomic number is 103. The atomic number of an element is equal to the number of protons and electrons in that element. Therefore, a lawrencium atom has one hundred three protons and one hundred three electrons. WebThe name lawrencium was officially announced in 1997 and was given after Ernest Lawrence, who discovered the device used for the discovery of various radioactive … pump pocket infection
