Selenium can gain 1 electron or loss 2, 4, 6 electrons.
Bromine will gain one electron to become Br-
Electrons lose in case of potassium. It looses 1 electron.
Potassium would lose electrons in all its reactions especially with Bromine.
In phosphene it gain 4 electrons. Phosphate lose 4 electrons
Some atoms lose electrons, some gain electrons, and some share electrons depending on what elements are involved and what compound is forming.
Strontium, as a metal, lose electrons forming divalent cations.
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
Selenium will gain two electrons and arsenic will gain three electrons
Potassium is more likely to lose its electron to become a positive ion.
silicon prefers to share electrons forming covalent bonds
It will lose 2 to form Sr2+
Beryllium would tend to lose its two electrons when forming a bond because it is easier to lose its two valence electrons rather than gain an additional five in order to obtain a full outer shell.
