Lithium atom Lithium atom A lithium atom is an atom of the chemical element lithium. Lithium is composed of three electrons bound by the electromagnetic force to a nucleus containing three protons along with either three or four neutrons, depending on the isotope, held together by the strong force. Similarly to the case of the helium atom, a closed-form solution to the Schrödinger equation for the lithium atom has not been found. However, various approximations, such as the Hartree–Fock method, can be used to estimate the ground state energy and wavefunction of the atom. The quantum defect is a value that describes
The ATOM Project The ATOM Project The ATOM Project (est. August 2012) is an international campaign by the Nazarbayev Center of Kazakhstan. The primary goal of the campaign is to build international support for the abolishment of nuclear testing. ATOM stands for "Abolish Testing. Our Mission." The goal is to achieve in force the Comprehensive Nuclear Test Ban Treaty through online petitions and other methods. The campaign is an initiative of the Nazarbayev Center whose mission includes the "promotion of nuclear responsibility, nuclear disarmament, and nuclear nonproliferation according to the vision of President Nursultan Nazarbayev (Kazakhstan)." Kazakhstan has historically been concerned about nuclear
