Thanks for your help Y'all:)

Answer 1

Selenium monochloride

Answer 2

Answer: The IUPAC name for $SeCl_2$ is selenium dichloride.

Explanation:

$SeCl_2$ is a covalent compound because sharing of electrons takes place between selenium and chlorine. Both the elements are non-metals and hence, will form covalent bond.

The nomenclature of covalent compound is given by:

• The less electronegative element is written first which is selenium.
• The more electronegative element is written then, and a suffix is added with it. The suffix added is '-ide'. Here, the atom is chlorine
• If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on..

So, the IUPAC name for $SeCl_2$ is selenium dichloride.
