What are molecular elements?
We might apply the term "molecular element" to an element that is not found as a single atom. Some examples might be in order to explain this.We often hear the term O2 applied to a gas in our atmosphere, which is the element oxygen. Oxygen is not generally found in the atmosphere in single atom units. It is found as diatomic molecules. We find that each oxygen atom has paired up with a "buddy" to form a "molecular element" and taken the form O2. Nitrogen, the most abundant gas in the atmosphere, also appears as the diatomic molecule N2.There are a few other elements that do not appear as "lone atoms" but will "hang around" with another atom of their kind. This is true of elemental gases, but not the inert or noble gases.
Explain why fluorine and chlorine undergo similar reactions?
Fluorine and chlorine are both halogens and belong to the same group in the periodic table. They have similar electronic configurations, making them chemically similar and likely to undergo similar reactions. Their reactivity is due to the tendency to gain one electron to achieve a stable octet configuration.
Explain why salt is a compound while the oxygen we breathe is not?
Salt contains atoms of two different elements: sodium and chlorine. Oxygen consists of a single element.
How many valence electrons in a fluorine atom will fluorine atoms form bonds Explain.?
Fluorine has seven electrons. Fluorine will form covalent and ionic bonds. Ionic- If it combines with any metal Covalent- If it bonds with a non-metal
Explain the use of chlorine in water purification plant?
because plant use chlorine as nutrient
Is fluorine used in dental practices?
Not exactly. Many toothpastes contain a fluoride which means that they contain what is known to chemists as a 'salt'. Table salt is a salt that is known to chemists as sodium chloride. It has chlorine in it but by being combined with sodium both the sodium and the chlorine are very different from the salt that you and I sprinkle on our foods. The same is true of the fluorides that are used in toothpastes. Incidentally I am not claiming either that fluorides are safe or unsafe, or good for you or bad for you. I'm merely trying to explain what fluoring has to do with some toothpastes.
Explain why the carbon chlorine bond photodissociates and the carbon fluorine bond does not?
This may be because of the reversed polarity (of CCl4) i.e. a positive halogen. The element sulfur should be able to form S(CH3)6 (theoretically feasible) and F3S≡C-SF3 (observed). These compounds contain sulfur in the formal oxidation state of +6. So, Chlorine should form at least Cl(CH3)3 or even Cl(CF3)5.It may be an overestimated electronegativity for chlorine (and for heavier halogens). The real electronegativity descending order may be Ne > F~O > N > C~Ar~He > Kr > Cl > Br > S > ....
Sodium chloride is a compound explain?
A compound is formed from 2 or more chemical elements linked by chemical bonds; and sodium chloride has sodium and chlorine linked by an ionic bond. And sodium chloride (NaCl) is a chemical compound.

Would you expect the bolling point of chlorine to be higher or lower than that of iodine explain?
The boiling point of iodine (184.3 0C) is substantially higher than the boiling point of chlorine (-34 0C). Each element occurs at standard temperature and pressure as diatomic molecules; iodine molecules have substantially more mass than chlorine molecules; dispersion forces will be higher beween iodine molecules as they have more electrons than chlorine molecules. Both these factors contribute, mass will alomost certainly be the predominant factor.
