1.	EETciseObserve the Modern Periodic Table and explain the gradation in reactivity of Halogen family
Answer» As studying the Modern periodic table, The group 17 contains the members of the halogen family. All of them have the general formula X2. A gradation is observed in their physical state down the group. Thus, fluorine (F2) and chlorine (Cl2) are gases. Bromine (Br2) is a liquid while iodine (I2) is a solid. Within this group, Fluorine is considered to to be highly reactive. The moment you move down the group the electro negativity decreases as the size of the atom increases. The sharing electrons move further away from the nucleus and so does its attraction power decrease.

Answer»

As studying the Modern periodic table, The group 17 contains the members of the halogen family.

All of them have the general formula X2. A gradation is observed in their physical state down the group.

Thus, fluorine (F2) and chlorine (Cl2) are gases. Bromine (Br2) is a liquid while iodine (I2) is a solid.

Within this group, Fluorine is considered to to be highly reactive. The moment you move down the group the electro negativity decreases as the size of the atom increases. The sharing electrons move further away from the nucleus and so does its attraction power decrease.
