What is the simple Definition of protons?
What is the simple Definition of protons?
Proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron. Every nucleus of a given chemical element has the same number of protons.
What is electron neutron proton?
Atoms are made of extremely tiny particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom, making up the nucleus. Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite. Neutrons have no charge.
What are neutrons Definition for kids?
Kids Definition of neutron : a particle that has a mass nearly equal to that of the proton but no electrical charge and that is present in all atomic nuclei except those of hydrogen.
What does the word vicinal mean in chemistry?
Vicinal (chemistry) In chemistry the descriptor vicinal (from Latin vicinus = neighbor), abbreviated vic, describes any two functional groups bonded to two adjacent carbon atoms (i.e., in a 1,2-relationship). For example, the molecule 2,3-dibromobutane carries two vicinal bromine atoms and 1,3-dibromobutane does not.
What is the kids definition of a proton?
Kids Definition of proton : a very small particle that exists in the nucleus of every atom and has a positive charge of electricity
Which is an example of vicinal coupling in chemistry?
The vicinal adjective is sometimes restricted to those molecules with two identical functional groups. The term can also be extended to substituents on aromatic rings. In 1 H NMR spectroscopy, the coupling of two hydrogen atoms on adjacent carbon atoms is called vicinal coupling.
How big is a proton compared to an electron?
: an elementary particle that is identical with the nucleus of the hydrogen atom, that along with the neutron is a constituent of all other atomic nuclei, that carries a positive charge numerically equal to the charge of an electron, and that has a mass of 1.673 × 10−27 kilogram.
