Protons and neutrons have approximately the same mass , but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron.
What are the similarities of protons and electrons?
Electrons and protons are similar in that both are charged sub-atomic particles . There is an equal number of electrons and protons in the atoms of each element, which corresponds to the atomic number that has been assigned to the element.
What are the difference between protons neutrons and electrons?
Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge. ... Neutrons are a type of subatomic particle with no charge (they are neutral). Like protons, neutrons are bound into the atom's nucleus as a result of the strong nuclear force.
What does protons neutrons and electrons have in common?
Protons and neutrons have almost the same mass and are both located in the nucleus of the atom. Protons are charged particles . ... Protons and electrons are charged particles. Neutrons have no charge.
What is one similarity between a proton and neutron?
Similarities between protons and neutrons: 1) They both have 3 quarks . 2) Both are nucleons ( i.e. they both make a nucleus except hydrogen nucleus which only has a proton.) 3) Both come under the category of baryons. 4 )In both of them strong nuclear forces act.
What is the main difference between protons and electrons?
| Electron Proton | The mass of an electron is 9.1 × 10 – 31 Kg. The mass of a proton is 1.67 × 10 – 27 Kg. | It can be easily added or removed from the atom. It is hard to be added or removed from the atom. | It is highly mobile. It is not mobile since they are present inside the nucleus. |

What are three differences between electrons and neutrons?
The difference between electron, proton and neutron is the charge they carry . Electrons are charged negative, protons are charged negative, and neutrons do not carry any charge. Rather they are neutral.
What is the similarities of neutrons and electrons?
Protons and neutrons have approximately the same mass , but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron.
What are two properties that protons and electrons have in common?
What are two properties that protons and electrons have in common? They are charged . Protons are positively shared and electrons are negatively charged. Which two subatomic particles are nearly identical in mass?
What are 2 ways that protons and neutrons are similar?
Protons and neutrons have approximately the same mass, about 1.67 × 10 – 24 grams. Scientists define this amount of mass as one atomic mass unit (amu) or one Dalton. Although similar in mass, protons are positively charged , while neutrons have no charge.
Who discovered the electron?
Although J.J. Thomson is credited with the discovery of the electron on the basis of his experiments with cathode rays in 1897, various physicists, including William Crookes, Arthur Schuster, Philipp Lenard, and others, who had also conducted cathode ray experiments claimed that they deserved the credit.
What element has 18 protons and 22 neutrons?
| Name Argon | Atomic Mass 39.948 atomic mass units | Number of Protons 18 | Number of Neutrons 22 | Number of Electrons 18 |

Are protons positive?
Protons and Electrons
A proton carries a positive charge (+) and an electron carries a negative charge (-), so the atoms of elements are neutral, all the positive charges canceling out all the negative charges. Atoms differ from one another in the number of protons, neutrons and electrons they contain.
Do protons and neutrons have the same mass?
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.
Why is an atom electrically neutral?
Electrons have electric charge of -1 and the number of electrons in an atom is equal to the number of protons . ... Heavier atoms tend to have more neutrons than protons, but the number of electrons in an atom is always equal to the number of protons. So an atom as a whole is electrically neutral.
Can protons move?
Atoms are made up of protons, electrons, and neutrons. ... Protons and neutrons never move from object to object . The energy that comes from these charged particles is called electrical energy. When the negative charges move to a neutral object, an electric charge builds up on both objects.
