1.	Why valency of elements in specific group is same?Plzzzzz answer it quickly I will make him /her brainliest
Answer» The periodic table is arranged in such a WAY that the number of shells of an ELEMENT determines its period and the number of valence electrons of an element determines its group. So, we can conclude that same group elements have same valence elements. So, group 1 elements have 1 valence electron Similarly group 2 elements have 2 valence electrons and group 3 have 3 and so on upto group 7. The number of valence electrons of elements belonging to same group is same. So, the valency of elements belonging to same group is same. Thus, a SPECIFIC group elements have same valency. Hope you understand my explanation. I also hope this must helps you.

The periodic table is arranged in such a WAY that the number of shells of an ELEMENT determines its period and the number of valence electrons of an element determines its group.

So, we can conclude that same group elements have same valence elements.

So, group 1 elements have 1 valence electron

Similarly group 2 elements have 2 valence electrons and group 3 have 3 and so on upto group 7.

The number of valence electrons of elements belonging to same group is same.

So, the valency of elements belonging to same group is same.

Thus, a SPECIFIC group elements have same valency.

Hope you understand my explanation.

I also hope this must helps you.
