What has a negative charge and a very small mass? Electrons are extremely small. The mass of an electron is only about 1/2000 the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an...
What particles have no mass? The two particles physicists know to be (at least approximately) massless—photons and gluons—are both force-carrying particles, also known as gauge bosons. Photons are associated with the electromagnetic force, and gluons are associated with the strong force....
What particle is no charge? neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67492749804 × 10−27 kg—marginally greater than that of the proton...
Which has a positive charge proton or electron? 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...
What subatomic particles identify an element? Answer and Explanation: Protons are the subatomic particle that determines the identity of an element. The atomic number, which can be found on the periodic table, tells us the number of protons in an atom...
Which subatomic particles are found in the nucleus quizlet? Neutrons and protons are located in the nucleus of an atom. What subatomic particles are not found in the nucleus? The nucleus only contains protons and neutrons. It does not contain electrons....
What are the 3 subatomic particles their charges and location? Proton (charge of +e, in the nucleus), Neutron (0 charge, in the nucleus), and Electron (charge of –e, outside the nucleus). Where are each subatomic particles located? In the middle of...
How was the first subatomic particle discovered? The first subatomic particle was discovered by J.J. Thomson in 1897. Thomson discovered the electron while conducting research on cathode rays. After watching the cathode rays respond to electrical and magnetic fields, he realized...
What charges do the 3 subatomic particles have? The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge. A third type of subatomic particle, electrons, move...
What is a negative charge ion called? Positively charged ions are called cations; negatively charged ions, anions. What is a net negative charge? If an object has more protons than electrons, then the net charge on the object is positive. If...
