How many forces act in an atom?

So the major forces acting in an atom are the strong force, the weak force and the electromagnetic force. Electromagnetic forces of attraction and repulsion based on charges keep the subatomic particles and make them move. These forces keep the electrons in an orbit around the positively charged nucleus. read more

All these four forces work together to maintain the stability of an atom but three of them have a greater effect particularly in the case of an atom or other subatomic particles. The force of Gravity mostly governs how massive celestial objects behave in each others presence. read more

· The strong forces and electromagnetic forces both hold the atom together. weak forces · Weak forces are important because they are responsible for stabilizing particles through the process of radioactive decay, in which a neutron in the nucleus changes into a proton and an electron. read more

Alpha decay is the emission of a helium nucleus from an atom, Beta decay is when an electron or positron is emitted from an atom, and Gamma decay is the emission of a high energy photon from an atom. The weak nuclear force is the odd one out of all the forces. read more
