Tellurium (Te) typically gains two electrons to achieve a stable electron configuration, as it is located in group 16 of the Periodic Table. By gaining two electrons, it forms anions with a -2 charge. In some cases, tellurium can also lose electrons, particularly in certain compounds, but gaining electrons is the more common behavior.
Silicon (Si) can gain or lose 4 electrons. It can either gain 4 electrons to have a stable octet configuration or lose 4 electrons to achieve a stable configuration.
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
It will lose 2 electrons.
