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
Argon has the same electron configuration as a potassium ion, as both species have 18 electrons with the electron configuration of [Ne]3s²3p⁶.
The smallest particle in a covalent bond is an atom. Covalent bonds form when two atoms share pairs of electrons to achieve a stable electron configuration.
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.
It is a molecule with a covalent bonding.
A shared pair of electrons results from the formation of a covalent bond. These electrons are shared between two atoms to achieve a stable electron configuration.
The particle of an atom that determines how it will bond with another atom is the electron, specifically the valence electrons. These are the electrons in the outermost shell of an atom and are responsible for chemical bonding. Atoms can share, gain, or lose valence electrons to achieve a stable electron configuration, leading to the formation of covalent, ionic, or metallic bonds.
the electrons
When a particle loses electrons, it becomes positively charged due to having more protons than electrons. Conversely, if a particle gains electrons, it becomes negatively charged as it has more electrons than protons. This imbalance in charge leads to the formation of a charged particle.
