We have also distinguish between the possible and common oxidation states of every element. # Electrons Net Charge 63 Many other rare types of decay, such as spontaneous fission or neutron emission are known. Neutron = atomic mass - proton Taught with enthusiasm. Neutrons stabilize the nucleus, because they attract each other and protons , which helps offset the electrical repulsion between protons. A neutron decays into a proton by one of the constituent down quarks decaying into an up quark, emitting a W boson, which decays into an electron and anti-neutrino. .ec_details_stock_total{ color:#666666 !important; } For a number to be classified as a prime number, it should have exactly two factors. 5 is the only prime number having the last digit as 5. .ec_image_container_none, .ec_image_container_none > div, .ec_image_container_border, .ec_image_container_border > div, .ec_image_container_shadow, .ec_image_container_shadow > div{ min-height:270px; height:270px; } Q. 1, 2, 19, 38.
