Question

In oxyacids,halogens are present in
.........hydride state

​

Answer 1

Explanation:

Group 17 Elements: Halogens

Group 17 elements are fluorine, chlorine, bromine, iodine, and astatine from the top to the bottom of the group. We know them by “halogens” because they are salt producers. The members of this group are highly similar to each other. They exhibit a regular pattern in the physical and chemical properties. Did you know that astatine is the only radioactive element in the group? All of these elements have seven electrons in their valence shell. Their electronic configuration is ns2 np5

We can see that they are one electron less from the nearest noble gas or octet configuration. These elements have a small size because of their effective nuclear charge. Hence, these do not possess the tendency to lose electrons. As a matter of fact, they gain an electron easily and complete their octet configuration. Halogens produce several oxoacids. These are nothing but the acids containing oxygen in the acidic group.
