what is periodic propert? How are the following properties very in a group and in a period? Explain.
Answers
Answer:
Group : Electronegativity values of elements decreases as we go down in a group. Period : Electronegativity increases along a period from left to right. Ionization energy increases from left to right in a period. Ionization energy decreases from top to bottom in a group.
Answer:
Periodic property : The physical and chemical properties of elements are related to their electronic configuration particularly the outershell configurations. The electronic configuration of valence shell of any two elements in a given period is not same. Due to this reason elements along a period possess different chemical properties with regular gradation in their physical properties from left to right. This is called periodic property.
In group of periodic table, Electropositivity increases on going from top to buttom in a group. Electropositivity decreases on going from left to right in a period . ... Atomic radius decrease on going from left to right in a period. Atomic radius increases on going from top to buttom in a group
