property? How do
the following properties changes in a
group and
period? (a) Atomic radices
(6) Jonization energy . (c) electrona fffinity
(4) electronegetivity
plz help me​

Answer 1

Answer:The phenomenon in which repetition of similar properties of elements occurs or reappears at atomic number intervals of 2,8,8,18,18 ,32 is called periodicity and these properties are called periodic properties. These include atomic radii, Ionisation potential, Electronegativity,Electron affinity etc

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
