What is a electron simple definition?
An electron is a negatively charged subatomic particle that can be either bound to an atom or free (not bound). An electron that is bound to an atom is one of the three primary types of particles within the atom -- the other two are protons and neutrons. Together, electrons, protons and neutrons form an atom's nucleus.

Anne Marie Helmenstine, Ph.D. Updated January 07, 2018. The primary parts of an atom are protons, neutrons, and electrons. Take a closer look at what a proton is and where it's found.
Where are protons found?
Free protons are found in plasma. About 90 percent of cosmic rays consist of protons.
What is the atomic number of an element?
The atomic number of an element is the number of protons an atom of that element contains. Because both protons and neutrons are found in the atomic nucleus, they are collectively known as nucleons. Protons, like neutrons, are hadrons, composed of three quarks (2 up quarks and 1 down quark).
What are the protons and neutrons in an atom?
Protons and neutrons make up the nucleus of every other kind of atom. In any one element, the number of protons is always the same. An atom's atomic number is equal to the number of protons in that atom. Protons are made of quarks. A proton is believed to be made up of 3 quarks, two up quarks and one down quark.
How many atomic mass units does a proton have?
The mass of the proton is about one atomic mass unit. The mass of the neutron is also about one atomic mass unit. The size of a proton is determined by the vibration of the quarks that are in it, and these quarks effectively form a cloud.
How many quarks are in a proton?
A proton is believed to be made up of 3 quark s, two up quarks and one down quark. One down quark has a charge of -1/3, and two up quarks have a charge of +2/3 each. This adds to a charge of +1. A proton has a very small mass. The mass of the proton is about one atomic mass unit.
What is the lightest atom?
A single atom of hydrogen (the lightest kind of atom) is made up of an electron moving around a proton. Most of the mass of this atom is in the proton, which is almost 2000 times heavier than the electron. Protons and neutrons make up the nucleus of every other kind of atom.
What does the U stand for in a periodic table?
The 'u' stands for an up quark, and the 'd' stands for a down quark. A proton is part of an atom. They are found in the nucleus of an atom along with neutrons. The periodic table groups atoms according to how many protons they have.
What is a proton?
Proton Definition. Andrew Zimmerman Jones is a science writer, educator, and researcher. He is the co-author of "String Theory for Dummies.". A proton is a positively charged particle that resides within the atomic nucleus.
How many times does a proton have a charge?
The proton has charge +1 (or, alternately, 1.602 x 10 -19 Coulombs), the exact opposite of the -1 charge contained by the electron. In mass, however, there is no contest - the proton's mass is approximately 1,836 times that of an electron.
Where is the proton located?
Andrew Zimmerman Jones. Updated January 16, 2018. A proton is a positively charged particle that resides within the atomic nucleus. The number of protons in the atomic nucleus is what determines the atomic number of an element, as outlined in the periodic table of the elements .
Is a proton a nucleon?
Proton Details. Since the proton is in the atomic nucleus, it is a nucleon. Since it has a spin of -1/2, it is a fermion. Since it is composed of three quarks, it is a triquark baryon, a type of hadron. (As should be clear at this point, physicists really enjoy making categories for particles.)
Who discovered the proton?
The proton was discovered by Ernest Rutherford in 1918 (though the concept had been earlier suggested by the work of Eugene Goldstein). The proton was long believed to be an elementary particle until the discovery of quarks. In the quark model, it is now understood that the proton is comprised of two up quarks and one down quark, ...
Where are protons located in an atom?
Protons are tiny particles inside the center of an atom. They they make up most of the weight of an atom, but they are still very small. In fact, if an atom was the size of a baseball stadium, each of its protons would still only be the size of a marble! This a model of an atom. Protons are in the center of an atom.
How to tell if an atom is unique?
Consider this--you have a last name, a family bloodline, and a birthday that are all unique to you. If you had to prove who you are, you could use all of this information to do so. Atoms are very similar--they each have an identity too! Their number of protons make them a unique type of element. For example, oxygen atoms have 8 protons, hydrogen atoms only have 1, and gold atoms have 79. This number is like the identity of an element. You can tell a lot about an atom just by counting its protons!
What makes an element unique?
The number of protons in an atom is what makes an element unique.
What is the center of an element?
Atoms are everywhere, and at the center of all of them are protons . An element's identity depends entirely on the number of protons its atoms have. Protons can be used to identify any type of element that exists.
What makes an element different from another?
You may notice that the element oxygen is a gas, the element chlorine has a strong smell, the element nickel has a silvery color, or many other features that are different among elements. What actually makes these elements different? The answer is simple: Their atoms have a different number of protons.
What happens if an atom gains or loses an electron?
That means that an atom of helium has 2 protons. So what happens if an atom gains or loses an electron? It becomes a new element. It really is amazing that the only thing that makes all the substances around us different from each other is the number of protons it has!
What are the smallest building blocks of solids, liquids, and gases?
Atoms are the smallest building block of solids, liquids, and gases. They are too small to see, but they make up things like your computer, the water you drink, and even the air you breathe. There are many types of atoms , including oxygen atoms , nitrogen atoms , and iron atoms. Each of these types are called elements.
