are particles that have either a positive or a negative charge.
Electron has a negative charge. An atom is made up of nucleons and the electrons. Nucleons are present in the core and consists of protons which are positive and neutrons which are neutral. The electrons revolve around the nucleons and are negative in nature. It was in 1897 that J.J. Thomson performed his '' Cathode Ray Experiments. Neutrons — Neutrons are particles having a mass 1/4 that of an alpha particle and 2000 times that of a beta particle. The neutron has no electrical charge. Risks and benifits of radiation particles and rays. Alpha radiation consists of helium nuclei and is readily stopped by a sheet of paper. When an electron is lost, the balance shifts with an extra proton, giving the atom a positive charge. The reverse is true for negatively-charged atoms, which have gained an electron. When particle balance is disrupted, yielding either a positive or negative atom (or molecule), they are no longer called atoms. Everything in the world, whether natural or synthetic, is made up of tiny structures called atoms, which are made of protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. The balance of these particles determines the overall charge of an atom. Confidence votes 91. protons have a positive charge, electrons are negative, and neutrons don't have one. 19 people found this useful. Like mass and spin, charge is a fundamental property of matter. Protons and electrons are particles of matter. Therefore, strictly speaking, positive charge does not mean protons and negative charge does not mean electrons. It is more accurate to say that protons and electrons carry or exhibit charge. Most molecules are neutral overall, but large ones tend to have one or more discrete areas that exhibit a negative or positive charge. Clothes dryers make positively- and negatively- charged particles to stick togehther, creating static cling. Beta particles— A beta particle is emitted during the radioactive decay of some unstable atoms. Beta particles can have either a negative charge or a positive charge and they have the same very small mass (1/2000 the mass of a neutron) regardless of charge. Report Abuse. 1  Positively charged atoms (ions) are called cations. Negatively charged atoms (ions) are called anions. 2  atoms that have lost an electron or electrons are positvely charged ions or cations. atoms that have gained an electron or electrons are negatively charged ions or anions. 3  they are called charged particles. neutrons, electrons, and protons are called subatomic particles when they are put in a group. but yeah atoms with a positive or negative charge are called charged particles. BLiS · 8 years ago. By convention, a proton's charge is positive and an electron's charge is negative. This is purely arbitrary and has no physical basis. The amount of charge carried by one proton (symbolized by +e) is 1.6 x 10^-19 coulombs and the amount of charge carried by one electron (symbolized by -e) is -1.6 x 10^-19 coulombs.
Yes,Beta particles can have either a negative charge or a positive charge.
