Step 2:: Understand the Definition of Valence
The valence of an element is determined by the number of electrons in its outermost shell (valence electrons) that can participate in chemical bonding.
Step 3:: Identify the Number of Valence Electrons
We are given that selenium has $$6$$ valence electrons.
Step 4:: Determine the Valence
- Or gain $$2$$ electrons to complete its octet
In general, the valence of an element is equal to the number of electrons it can gain, lose, or share to achieve a stable electron configuration.
Step 5:: Confirm the Valence
In most chemical compounds, selenium typically exhibits a valence of $$2$$.
Final Answer
The valence of selenium is 2.
