Using the periodic table, we have to identify the element with given information -Two electrons are added to an oxygen atom. Concept introduction : The electron configuration is the allocation of the electrons of atom or molecule in the atomic or molecular orbitals. It describes that each electron is moving independently in the orbital, in a field created by all the other orbitals. As per the rules of quantum mechanics , for the systems having only one electron, the energy is associated with each of the electronic configurations and, upon some conditions, the electrons are able to move from one electron configuration to another by emitting or absorbing the quantum of energy, in form of a photon.

What is the pH of a 1.0 L buffer made with 0.300 mol of HF (Ka = 6.8 × 10⁻⁴) and 0.200 mol of NaF to which 0.160 mol of NaOH were added?

Determine if the following salt is neutral, acidic or basic. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR. Be sure to include the proper phases for all species within the reaction. NaN₃
