Please explain (5) in detail.(Assertion-Reason) 5
: Mass numbers of most of the elements are fractional.
: Mass numbers are obtained by comparing with the mass number of carbon taken as 12.
Limiting line in the balmer series has a wavelength of 36.4
Statement I: Mass numbers of most of the elements are fractional
Because : The atomic mass are relative masses of atoms compared with mass of atom C-12 normally taken as 12 whence the mass numbers are fractional
