The element selenium (Se) bonds with chlorine (Cl) to make the formula SeCl2 Chlorine is more electronegative than selenium. What is the name of this molecular compound?

The name of the molecular compound is selenium dichloride (SeCl2).  

•Due to sharing of electrons between selenium and chlorine, Selenium dichloride is considered as covalent compound.  

•Both the elements are non-metals, and thus, would give rise to covalent bond.  

•Selenium is the least electronegative element of the two, so it is written first.  

•After that the more electronegative element is written, and then addition of suffix is done, that is, -ide.  

•If atoms of an element is more than one, then prefixes are supplemented that is mono for 1 atom, di for two atoms, and tri for three atoms.  

Thus, the name of the molecular compound is selenium dichloride.

Selenium dichloride

Explanation:

Selenium (Se) and Chlorine (Cl) are both elements capable of combining together to form a compound with the chemical formula; SeCl2. Since the chlorine atom is more electronegative than selenium atom, the chlorine pulls more electrons towards itself to form an IONIC bond.

The SeCl2 compound formed is called Selenium dichloride as two atoms of Chlorine are needed to combine with one atom of Selenium to form the compound.

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.
