Group VII the halogens quiz

Revising Group VII the Halogens with quizzes

(Group VII the halogens quiz for students doing the GCSE, GCE Advanced level and necta)

Here we're going to look at all the elements in group 7, their physical properties and the uses of some of these halogens.

All the Group VII elements are known as the halogens and these elements include (F) Florine, (Cl) Chlorine, (Br) Bromine, (I) Iodine, (At) Astatine and (Ts) Tennessine.

Because of their high reactivity, halogens only exist in a combined form and can't be found as free elements in nature with Fluorine being the most abundant of all the halogens in the crust of the Earth. Tennessine and Astatine do not happen in nature and this is because they are mad of only short-lived isotopes which are Radioactive. 

Physical Properties of Halogens

Halogens are colored, Chlorine being Pale green and a gas, Bromine Brown and a liquid, Iodine being purple black and a solid

The melting point and the boiling points of these elements increase as we descend the group 

Uses of some Halogens

• Fluoride can be found in numerous regular items, including toothpaste, nutrient enhancements, infant recipes, and even open water. Be that as it may, over-consumption of fluoride can be lethal. 
• Chlorine represents about 0.15 percent of human body weight and assumes a few significant parts in the body's working. Mixes of both chlorine and bromine are utilized as disinfectants for cleansing. 
• Iodine is fundamental for the working of the body's thyroid organ. Without iodine, thyroid chemicals can't be created, which prompts hypothyroidism. 
• Medication applicants that have consolidated halogen iotas are normally more lipophilic and less water-dissolvable than their analogs, thus have improved infiltration through lipid layers and tissues. Along these lines, some halogenated medications can collect in fat tissue.
