Se
Se2- anion
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
Yes.An alpha particle is the nucleus of a helium atom, with no electrons. There are 2 protons and 2 neutrons.
An ion is a particle that has an unequal number of protons and electrons, resulting in a net positive or negative charge.

The particle is an atom of selenium (Se). It has 34 protons and 34 electrons, since the number of protons equals the number of electrons in a neutral atom. The electron configuration given ("1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6") matches that of selenium.
Yes.An alpha particle is the nucleus of a helium atom, with no electrons. There are 2 protons and 2 neutrons.
They are neutrons, protons and electrons.
In an atom, 10 protons and 10 electrons. (# of protons = atomic number) =)
These particles are: protons, neutrons and electrons.
Electrons are the fastest moving particles among protons, neutrons, and electrons.
