Answer:
The C4+ ion has the smallest ionic radius
Explanation:
In the periodic table, the size of an atom increases on going downwards in a group.
On the other hand, in a period, size decreases on going from left to right
The size of cation is smaller than its parent atom.
Lithium-ion (Li+) is the most left so it has the biggest radius.
More to the right ( this means a smaller ionic radius) , we have Berylium-ion (Be2+).
More to the right, so smaller than Be2+, we have B3+
The ion the most to the right, we have C4+
The C4+ ion has the smallest ionic radius
Li+ > Be2+ > Be3+ > C4+
The ion is which has the smallest ionic radius is C4+.
The size of the atomic radius in the periodic table increases as we go down
the group while the atomic radius size decreases from left to right across the period. It is also pertinent to note that cation are usually smaller than its
parent atom.
The order of the elements from left to right across the period include Li+,
Be2+ , Be3+ , C4+
Therefore the atom with the biggest atomic radius is B3+ and the smallest is
C4+.
The C4+ ion therefore has the smallest ionic radius
Li+ > Be2+ > Be3+ > C4+
