If an atom has 104 electrons, 157 neutrons, and 104 protons,
what is its approximate atomic mass?
What is the name of this element?
mass of neutron = Mn = 1.00898 u
mass of proton = Mp = 1.00759 u
atomic mass = (number of neutrons*mass of neutron ) + (number of proton*mass of proton)
atomic mass = (157*1.00898) + (104*1.00759) u = 263.2 u
<<---answer
atomic number = 104
element = Rutherfordium <<--answer
