The ionic size decreases in the order

The size of species I,I^(o+) and I^(ө) decreases in the order

The size of Pb,Pb^(2+) and Pb^(4+) decreases in the order:

Na^(+), Mg^(2+), Al^(3+) , and Si^(4+) are isoelectronic ions. Their ionic size will follow the order

Na^(+), Mg^(2+), Al^(3+) , and Si^(4+) are isoelectronic ions. Their ionic size will follow the order

The ionic character of the metal halides MCl , MI,MBr, MF decreases in the order

The size of species I, I^(+) and I^(ɵ) decrease in the order.

The size of species I, I^(+) and I^(ɵ) decrease in the order.

Arrange Al^(3+),Na^(+)&Mg^(2+) ions in the decreasing order of their ionic radii and explain the order.

Arrange O^(2-),N^(3-) and F^(-) ions in the decreasing order of their ionic radii and explain the order.

Assertion : The ionic radius follows the order I^(-)ltIltI^(+) . Reason : Smaller the value of Z/e, the larger the size of the species.
