Which element has larger atomic size Fe or Ni?

Answer 1

Fe ................because from left to right in periodic table the atomic size decreases so............Ni have atomic size smaller than Al

Answer 2

Ni (Nickel) has a larger atomic size than Fe (Iron). This is because Nickel has more electrons and energy levels, which leads to a greater atomic radius compared to Iron. Additionally, Nickel is located in the same period as Iron on the Periodic Table, but it is to the right of Iron, indicating a larger atomic size.
