Question

Among Na+ , Mg2+ and Al3+ write increasing order of atomic radius

Answer 1

hey mate

since we know that the atomic radius decreases from left to right and increases from top to bottom so the atomic radius in increasing order are

Na+<Mg2+<Al3+

plz mark as the brainliest

hope so it helped

Answer 2

Answer: The order is Al3+ > Mg2+ > Na+

Explanation: More the positive charge, more the number of protons than electrons, because, if an element has one positive charge , it means that is has lost one electron, and so, it has one proton greater than the number of electrons! So, in +3 , it has three number of protons greater than electrons! And we know that proton pulls! And if the number of protons becomes a lot greater than the electrons, then pulling capacity increases and so the radius decreases!
