What is the main difference between electrons and protons?
Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom’s nucleus as a result of the strong nuclear force .
What are 2 differences between protons and electrons?
Atoms are made of extremely tiny particles called protons, neutrons, and electrons. ... Protons have a positive charge. Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite .
How are protons and electrons similar and different?
Electrons and protons are similar in that both are charged sub-atomic particles . ... They are different in that electrons are virtually weightless, while protons have measurable weight. Electrons orbit the nucleus of an atom, attracted to the positively charged protons inside the same nucleus.
Why are protons different from electrons?
Protons are electrochemically positive in charge and the Neutrons are electrochemically neutral in charge. Together the protons and Neutrons make up the mass of the atom. Electrons are electrochemically negatively charged particles that move random around the nucleus.
What are the similarities and differences among protons 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 the three difference between protons neutrons and electrons?
| Proton Neutron Electron | They are positively charged They are neutral They are negatively charged |

What is the relationship between protons and electrons?
Electrons contribute greatly to the atom’s charge, as each electron has a negative charge equal to the positive charge of a proton. Scientists define these charges as “+1” and “-1. ” In an uncharged, neutral atom, the number of electrons orbiting the nucleus is equal to the number of protons inside the nucleus .
What do 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.
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 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?
Why are electrons needed?
Electrons are also important for the bonding of individual atoms together . With out this bonding force between atoms matter would not be able to interact in the many reactions and forms we see every day. This interaction between the outer electron layers of an atom is call atomic bonding. It can occur in two forms.
Do protons always equal electrons?
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. When one or more electrons is stripped away from an atom, it becomes positively charged.
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.
Where are electrons found?
Protons and neutrons are heavier than electrons and reside in the nucleus at the center of the atom. Electrons are extremely lightweight and exist in a cloud orbiting the nucleus .
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.
