Why are Group 7 elements called halogens?
They are called halogens as they form salts with metals. The term "halogen" is derived from the Greek language and means salt producers.
Why are halogens reactive?
To the question, " are halogens reactive", the answer is yes and the reason lies in their electron configuration. Atoms of all the halogens have seven valence electrons. The halogen atoms are very close to a stable electron configuration. This explains why halogens are reactive.
Where Are Halogens on the Periodic Table?
It places elements with similar chemical properties in groups. The halogens are located in group 17 on the periodic table.
What are Halogens?
Halogens is the collective name given to a group of non-metallic elements. The name "halogens" owes its origin to the Greek language. "Halogens" means "salt formers". Halogens can be defined as elements that form salts when they react with metals. There are six halogens- fluorine, chlorine, bromine, iodine, astatine, and tennessine. Tennessine is the latest addition to the halogen family and is named after the state of Tennessee, US; but it is still not considered a true halogen because it is a synthetic element.
Why are halogens always found in the combined form?
The reactive nature of halogens is the reason why they are always found in the combined form.
What is the boiling point of iodine?
Boiling points: The boiling points of the halogens show a regular gradation. The boiling points from fluorine to iodine are 85.01K, 239.18K, 331.93K, and 457.5K. The boiling point of astatine is not known. This trend in the halogens' property is due to the van der Waal's forces existing in the halogen molecules. These forces are stronger when the atoms have a large number of electrons. More energy is required to overcome these forces. This results in a graded increase in boiling points.
Why are halogens found only as compounds?
Halogens are never found in nature as elements; they are found only as compounds because of their reactive nature.
How does reactivity affect the group?
Reactivity: Reactivity can be explained as to how easily an element forms compounds with other elements. Halogens' reactivity decreases down the group. The halogens' electron configuration is {eq}ns^ {2}np^ {5} {/eq}. The halogen atoms are just one electron short of completing their octet. So, the halogens accept an electron to fill their shells. As the halogens' atom size increases, it is difficult for the large atoms to take in the extra electron. The attractive force the nucleus exerts on the incoming electron diminishes down the group. So reactivity of halogens decreases on moving down. This trend is shown as: {eq}F > Cl > Br > I > At {/eq}.
Which group of elements are less reactive?
