A layered technology is divided into 4 layers:- 1. A quality Process :- Any engineering approach must rest on an quality. 2. Process :- Foundation for SE is the Process Layer 3. Methods :- SE methods provide the "Technical Questions" for building Software. 4. Tools :- SE tools provide automated or semi- automated support for the "Process" and the "Methods".
Selinium (Se) and tellurium (Te) are both used in solar cells and are in the same group in the Periodic Table as sulfur. These two elements are commonly combined with cadmium (Cd) in solar cells (either CdSe, CdTe, or mixtures of Cd, Se and Te all together (usually written CdSexTe1-x).

se and sometimes gain electrons. Atoms with eight valence electrons do not easily lose electrons

Se has to gain two electrons
Aluminum and Selenium are expected to lose electrons in their chemical reactions, as they are metals located on the left side of the periodic table. Meanwhile, elements like Sn (Tin) and Br (Bromine) are expected to gain electrons as they are nonmetals located on the right side of the periodic table.
Selenium can gain up to 2 electrons to achieve a stable electron configuration.
34 electrons
CoSe is an ionic compound composed of cobalt (Co) and selenium (Se). Cobalt typically forms ionic compounds with nonmetals like selenium due to its tendency to lose electrons and selenium's tendency to gain electrons.
The symbol for a selenium atom gaining two electrons is Se2-.
An atom of selenium has 34 electrons.
The Lewis theory states that atoms form bonds by sharing electrons. Strontium (Sr) is in group 2 and would lose 2 electrons, while selenium (Se) is in group 16 and would gain 2 electrons to achieve a stable octet. Therefore, SrSe2 would be the formula of the compound that forms between strontium and selenium.
Oxygen, O ,and selenium Se. O (oxygen) would have to gain two electrons in order to achieve the same number of electrons as Ne (neon, a noble gas). Selenium would gain two to achieve the same number of electrons as Kr, krypton (noble gas). They would form the oxide, O2- and selenide Se2- ions
By February 15, 1942, Japan had reached the height of its conquest of SE Asia. That day was the day they took over Singapore. After that, they began to lose their land back.
