Sulfur and Fluorine are nonmetals so they will form covalent bonds to gain stability. To do so, they will follow the octet rule: they will share enough electrons so as to have their valence shell complete with 8 electrons.
Sulfur is in the Group 16 in the Periodic Table and has 6 valence electrons. Thus it must share 2 pairs of electrons to reach the octet.
Fluorine is in the Group 17 in the Periodic Table so each F has 7 valence electrons. Thus, each F needs to share 1 pair of electrons to reach the octet.
As a consequence, they will be bonded in the order F - S - F, with a single bond between each pair of atoms.

Answer:
Explanation:
The unbalanced nuclear equation is
It is convenient to replace the question mark by an atomic symbol, , where x = the atomic number, y = the mass number, and Z = the symbol of the element .
Then your equation becomes
The main point to remember in balancing nuclear equations is that **the sums of the superscripts and the subscripts must be the same on each side of the equation**.
Then
84 = x + 2, so x = 84 - 2 = 82
210 = y + 4, so y = 206
Element 82 is lead, so the nuclear equation becomes
Answer:
2. Makes accurate predictions based on only a small amount of empirical evidence
Explanation:
For a phrase or scientific finding to be considered a law, there has to be clear evidence and facts to support that specific finding. In the case of the evolution theory, the evidence is not clear enough to make it a law
