Explanation:

Covalent compounds are formed when non - metals share electrons. Selenium (Se) and bromine (Br) are both non - metals. In covalent compounds, the empirical formula is determined by the ratio of atoms based on their valence electrons. Selenium has a valence of + 4 (in some common compounds with bromine) and bromine has a valence of - 1. To balance the charges (in terms of electron sharing ratio), we need 4 bromine atoms for 1 selenium atom.

Answer:

Empirical formula: \(SeBr_4\)
Name: Selenium tetrabromide
