Answer:
Increase in atomic number , atomic mass, electro-negativity, ionization, electron affinity.
Decrease in size.
Explanation:
On moving from left to right in a periodic table, the following changes occurs –
a) The atomic radius of elements reduces due to increase in strong attractive atomic forces which further cause increase in both the electronegativity and ionization
b) The atomic number increases due to the increase in number of neutron and proton.
c) There is also increase in atomic mass
d) Reduced size causes increase in electron affinity while moving from left to right
