We can define atomic mass the total of number of protons and number of neutrons in an atom or isotope.
<span>So when an isotope of yttrium has 39 protons and 59 neutrons, its atomic mass is equal to;
number of protons + number of neutrons = 39 + 59 = 98</span>
A species with a positive charge will have a net attraction to a species with a negative charge. Among the choices, N3- is the only one attracted to a positive charge.
A rapid release of stored up energy
When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises.
You use a nucleus with inflection on the arm processor.
