Question

Elements in a group generally possess similar properties, but elements along a period havedifferent properties. How do you explain this statement?

Answer 1

the properties of elements depends mainly on the differentiating electron

in a group the differentiating electron enters same sub-shell whereas in period it is different

Answer 2

Answer:

Explanation:

physical and chemical properties of elements are related to their electronic configuration particularly outermost shell configuration there for all the elements in a group should have similar chemical properties similarly across the table from left to right in any period elements get an increase in atomic number by 1 unit between any two successive elements therefore the electronic configuration of valence shell of any two elements in a period is not same due to this reason elements along A period poses different chemical properties
