A single neutron has a mass of 1.008665 atomic mass units. An atomic mass unit is a very small unit of mass equal to one-twelfth of the mass of a carbon-12 atom. Neutrons have a slightly larger mass than protons, which have a mass of 1.007277 atomic mass units.Know More
The mass of neutrons and protons can be used to calculate an atom's atomic mass, which is equal to the combined mass of the neutrons and protons in its nucleus. Atomic mass, which is expressed in atomic mass units, can be calculated by multiplying the number of neutrons by 1.008665 and the number of protons by 1.007277, and then adding these two products together.
Neutrons are atomic particles that carry a neutral charge and are found in the nuclei of atoms. Atoms of an element that contain different numbers of neutrons are called isotopes. An element's average atomic mass is calculated by multiplying the mass of each isotope by its relative abundance in nature, and then adding these products together. Generally, the atomic mass displayed for each element on the periodic table is the average mass of all of its natural isotopes. Sometimes atomic mass is rounded to the nearest whole number; this number is known as an element's mass number.Learn more about Particle Physics
Electrons have a relative mass of 9.1 x 10^-31 kilograms, or 0.51 megaelectron volts. They are a lot smaller than protons and neutrons; and, an electron is roughly 0.054 percent of the mass of one neutron.Full Answer >
An electron jump from an outermost energy level to the innermost or ground level would emit the highest frequency photon. A greater the drop in energy levels results in a higher frequency of the emitted photon.Full Answer >
Nuclear energy forms when atoms of uranium are split in a nuclear reactor through a process called fission. Small, hard ceramic particles containing uranium fuel are inserted into the reactor to produce steam, which turns the turbines in the reactor to produce electricity.Full Answer >
Gene cloning occurs when a specific gene from a strand of DNA has been extracted and copied from an organism. Nearly any tissue source can be used for cloning, as long as there is not widespread degradation. DNA can also be extracted from RNA using a process called reverse transcription.Full Answer >
