1.	In an atom , the number of neutrons is 58.7% more than that of protons. The number of electrons in the neutral atom is 92. Find out the number of protons , neutrons and mass number and represent the atom with atomic number and mass number.
Answer» Solution :Since the number of ELECTRONS in the neutral ATOM is 92. `THEREFORE ` Atomic number (Z)is 92 and number of PROTONS is 92 Number of neutrons `=92+(58.7xx92)/(100)=146` Mass number (A) =atomic number + number of neutrons Mass number =92 + 146 =238 Representation `""_(92)X^(238)`
