← ScienceWhich outcome occurs when electron affinity increases across period?
A)Atomic radius usually decreases✓
B)Melting point always increases
C)Ionization energy starts decreasing
D)Electronegativity remains approximately constant
💡 Explanation
The atomic radius usually decreases because increased effective nuclear charge pulls electron orbitals closer, therefore resulting in stronger attraction and smaller sizes, rather than increased radius under same conditions and increased radius under different valence electrons.
