Elemental sulfur occurs as octatomic molecules, 63.2 g F2 are needed to react completely with 17.8 g S8 to produce SF6 .
<h3>What is octatomic molecules?</h3>
When stable under normal temperature and pressure circumstances, an octatomic element is a chemical element that has eight atoms arranged in a group. Sulfur, symbol S8, is the classic example, but red selenium is also an octatomic element that is stable at ambient temperature.
A molecule with eight sulfur atoms has a puckered ring or crown structure. Sulfur is in an octet state when it contains two more electrons than the six in its outermost shell. Sulfur has an atomic number of 16 and an electrical configuration of 2, 8, 6.
Other elements (S, Se, and Te) exist as octatomic solids while oxygen is a diatomic gas at normal temperature.

False. Many theories have been altered over the years due to new information. Scientists usually accept new evidence so they can advance their own research.
Answer:
ionic compound
Explanation:
An ionic compound and a covalent compound react differently when dissolved in water (H2O).
The ionic compounds when dissolved in H2O, undergo a physical change called dissociation. In this change the molecules of water surround the ionic compound and ions of ionic compound disperse uniformly in the water. The complete dissociation of ionic compounds in H2O makes it a strong electrolyte and solution will conduct an electric current.
Some of the covalent compounds also conduct electricity as when they dissolve in H2O, the molecule of covalent compound react chemically with the solvent to produce ions. Generally, covalent compounds are weak electrolytes and do not conduct much electricity as ionic compounds but exception are their such as HCl and benzene.
