The correct sequence, which shows decreasing order of the ionic radii Off the element is. option A. AL 3 plus.> MG2 plus.> N A Plus.> F -.> O 2 -. option B N A +> MG, 2 plus >AL, 3 +> O, 2 ->. F, -. option c. N a +> F, - >MG, 2 +> O, 2 -,> Al3 +. Option D. O 2 -> F, -> Na plus> MG, 2 +>al 3 +.

The correct sequence, which shows decreasing order of the ionic radii is:

Option A. Al3+ > Mg2+ > Na+ > F- > O2-

Arrange the following in increasing order of ionic retire. C 4 -. N 3 -. F -. O 2 -.

The correct sequence, which shows increasing order of the ionic radii is:

C4- < N3- < O2- < F-

The symbol and iupac name for the element with atomic number 120 respectively, are.

The symbol for the element with atomic number 120 is Ubn (Unbinilium). However, as of now, since element 120 has not been officially discovered and named, it does not have an IUPAC name.

The correct order of ionization energy for carbon nitrogen. and oxygen atom is.

The correct order of ionization energy for carbon, nitrogen, and oxygen atoms is:

1. Nitrogen (N)
2. Oxygen (O)
3. Carbon (C)

The ionization energy generally increases across a period from left to right in the periodic table. In this case, nitrogen has the highest ionization energy, followed by oxygen, and then carbon.
