charge depends on the number of excess electrons in the body. In the same manner, we can explain the positive change of a body. Here the number of electrons becomes lesser than that of protons. The positivity of the body depends on the difference between protons and electrons in the body....

Together, protons and electrons form an atom'snucleus. A proton has a positive charge that counters the electron's negative charge. When an atom has the same number of protons and electrons, it is in a neutral state. Electrons are unique from the other particles in multiple ways. They exis...
Here’s a question you’ve probably never considered: Why are all electrons the same? Every electron in the universe has exactly the same mass, exactly the same charge, and if you think about it, there’s no reason why they’d have to be. ...
What is the atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons? Which atom has the smallest number of neutrons? What is an atom that has a different number of neutrons than other atoms of the same element?
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 ...
Electrons, protons, and neutrons make up an atom. Now, the protons and neutrons are quite lazy, simply staying at the center of the atom in a space called the nucleus. However, electrons are busy, regularly participating in the formation of bonds with other atoms. ...
There is also such a thing asantimatter, which is not the same as dark matter. Antimatter consists of particles that are essentially the same as visible matter particles but with opposite electrical charges. These particles are called antiprotons and positrons (or antielectrons). When antiparticl...
