An atom has a mass number of 24 and 13 neutrons. what is the atomic number of this atom?Atomic and Mass Numbers:The atomic number of an atom is equal to the number of protons found in the atom's nucleus. The mass number of an atom is the total number...
The nucleus is made of one or more protons and a number of neutrons. Only the most common variety of hydrogen has no neutrons. More than 99.94% of an atom's mass is in the nucleus.Where are atoms made of?Atoms are made up of protons and neutrons located within the nucleus, with ...

An atomic number of 1 means the atom is hydrogen, atomic number 2 means helium, 3 means lithium, 4 is beryllium, and so on. The total number of protons and neutrons added together is called the relative atomic mass. Hydrogen has a relative atomic mass of 1, while helium's relative ...
Protons and neutrons have approximately the same mass. However, one proton is about 1,835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes ...
The most convincing evidence that of mass energy equivalence principle operates in nature comes from the results of nuclear physics. It is central to our understanding of nuclear energy and harnessing it as a source of electrical power. Using this principle, we can easily explain the concept of ...
