Question

the physical and chemical properties of elements belonging to the same group are simliar ,why?​

Answer 1

Answer:

Elements in the same group (in the periodic table) have similar physical and chemical properties. This is because their atoms have the same number of electrons in the highest occupied energy level (valence electrons) which are responsible for bonding characteristics.

Answer 2

Answer:

The chemical and physical properties of any elements rely on the quantity of valence electrons. In periodic table elements are in same group are having same quantity of valence electrons. This is why elements present in the same group are having similar chemical and physical properties.
