What is the trend of the following when we move from left to right in a period? a)Atomic radius
b)Atomic size
c) Ionization energy
d)Electron affinity
e) Electronegativity
f) Metallic character

Moving from left to right across a period, atoms become smaller as the forces of attraction become stronger. This causes the electron to move closer to the nucleus, thus increasing the electron affinity from left to right across a period. Electron affinity increases from left to right within a period

Atomic size

Explanation:

b. atoms in metallic solids are not arranged in a regular pattern
