Answer:

The periodic law demonstrated in halogens by:

All halogens have the same number of valence electrons and similar chemical properties

Explanation:

  • The halogen are located in the group of seven A of the periodic table example of halogen are iodine and chlorine.
  • The halogens are the reactive non-metals in the periodic table, it reacts with alkali metals.
  • Halogen responds with iron, iron wool outbreak into flames when it responds with fluorine gas.

Halogens is defined as the group of 7 periodic table. As, every periodic table contains 7 valence electrons and they only need 1 more to complete an outer shell, that is why they are extremely reactive. And according to the law that recurring patterns of the properties of elements arise when they are arranged in order of increasing atomic number. As the halogen all act very similarly with each other in chemical reaction, it is true.
