Here, protons and neutrons are the larger particles, whereas electron is quite small in size. Therefore, atomic mass is the total number of protons and neutrons present in an Atom. Smaller in size, the electrons are not taken into consideration. Atomic Mass Unit An Atom, being very small ...
Subatomic particles are the individual protons, neutrons and electrons that make up the composition of atoms. With the help of the periodic table of elements, we can calculate how many subatomic particles there are in a given atom. Protons and neutrons are found within the nucleus of an atom ...
Electron volts are a common unit of measurement in particle physics to describe the potential energy of the system and balance conservation of energy. We might talk about the rest mass or momentum of protons, neutrons, muons, pions, or electrons using electron volts. Electric Potential Energy Exa...
Calculate the mass number of an atom that is made up of 38 protons, 52 neutrons, and 38 electrons. The hydrogen atom contains 1 proton and 1 electron. The radius of the proton is approximately 1.0 fm (femtometer), and the radius of the hydrogen atom is ...
electrons have so much less mass than protons and neutrons that they don't factor into the calculation. So, the atomic mass is the sum of the masses of protons and neutrons. There are three ways to find atomic mass, depending on your situation. Which one to use depends on whether you ...
We’ve just learned the simplest way to determine the weight of an atom of any particular element. Let’s perform the check using the weights of electrons, protons, and neutrons. This would not be so easy if gold had a number of isotopes. Gold has only one stable isotope however. What...
Calculating the ionization energy of an atom constitutes a part of modern physics that underlies many modern technologies. An atom consists of a central nucleus that contains positively charged protons and a number of neutrons specific to the given atom. A number of negatively charged electrons orbit...
How did Niels Bohr describe electrons in his atomic model? How are subatomic particles responsible for an atom's characteristics? Can an atom become charged? If so, how? How to find the energy of quantum light What is the size of a hydrogen atom in meters?

Atoms are the smallest individual unit of an element consisting of all of the properties of that element. Atoms consist of a nucleus containing protons and neutrons that is orbited by nearly massless electrons. Protons and neutrons weigh about the same as each other. Each proton contains a posi...
