Complete step by step answer: Given, Mass number is 88. .tags a, 17 In a neutral atom, the number of protons equals The number of electrons. The first two columns on the left side of the periodic table are where thessubshells are being occupied. Example - 71 is a prime number and it can be written as 71 = 6 12 - 1. If there are too many or too few neutrons for a given number of protons, the resulting nucleus is not stable and it undergoesradioactive decay. In the periodic table, the elements are listed in order of increasing atomic number Z. The neutron has a mean square radius of about 0.81015 m, or 0.8 fm, and it is a spin- fermion. neutrons The number 38 is divisible by 1, 2, 19, 38. Neutrons stabilize the nucleus, because they attract each other and protons , which helps offset the electrical repulsion between protons.
