Se2- anion
Se
The element with atomic number 34 is selenium (Se) and when it accepts two electrons it forms Se-2 ions which has 34 protons and 36 electrons with the electronic configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6
electrons electrons
True, it lost its only two electrons, which makes it consist of 2 protons and 2 neutrons

This is the ion selenium(2-).
the electrons
A molecule is the neutral particle formed when electrons are shared between atoms. The charge is neutral when electrons are shared, negative when they gain electrons, and positive when they lose electrons.
In a redox reaction the number of electrons lost by one particle is equal to the number of electrons gained by another particle.
