An atom a fundamental piece of matter. ... An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons. The protons and the neutrons make up the center of the atom called the nucleus and the electrons fly around above the nucleus in a small cloud.
Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you. Atoms are composed of particles called protons, electrons and neutrons.
Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom (which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside.Jan 28, 2017
You can simply subtract the atomic number from the mass number in order to find the number of neutrons. If the atom is neutral, the number of electrons will be equal to the number of protons. 1. Your mass number is the total number of neutrons and protons within the atom.Oct 22, 2016
Protons also play a significant role because the tendency for an atom to either lose, gain or share electrons is dependent upon the charge of the nucleus. Therefore, we can say that the chemical reactivity of an atom is dependent upon the number of electrons and protons, and independent of the number of neutrons.
A proton is one of the most important types of subatomic particles. Protons combine with electrons and (usually) neutrons to make atoms. Protons are nearly the same size as neutrons and are much larger than electrons.Sep 17, 2010
