In what row and group would you find the element with configuration [Ne] 3s² 3p³?

Arrange the following ions in order of increasing ionic radius: N³⁻, O²⁻, F⁻, Ne

Which of the following is the electron configuration of the iron(II) ion (Fe²⁺)?

The successive ionization energies of a certain element are:I₁ = 589.5 kJ/mol, I₂ = 1145 kJ/mol, I₃ = 4900 kJ/mol, I₄ = 6500 kJ/mol, I₅ = 8100 kJ/mol.This pattern suggests the element is:
