An unielectronic ion of element A (atomic number of element 'A' is 'n') has velocity of electron in x^{th }orbit equal to velocity of electron in H-atom in nth orbit. Group number of element A in modern periodic is \lbrack if kinetic energy of electron in H-atom in x^{th} orbit is more than 0.2125 eV/atom and x≠ n\rbrack

An unielectronic ion of element A (atomic number of element 'A' is 'n'

1.	An unielectronic ion of element A (atomic number of element 'A' is 'n') has velocity of electron in x^{th }orbit equal to velocity of electron in H-atom in nth orbit. Group number of element A in modern periodic is \lbrack if kinetic energy of electron in H-atom in x^{th} orbit is more than 0.2125 eV/atom and x≠ n\rbrack
Answer» An unielectronic ion of element A (atomic number of element 'A' is 'n') has velocity of electron in x^{th }orbit equal to velocity of electron in H-atom in nth orbit. Group number of element A in modern periodic is \lbrack if kinetic energy of electron in H-atom in x^{th} orbit is more than 0.2125 eV/atom and x≠ n\rbrack
