Protons and neutrons have approximately the same mass. However, one proton is about 1,835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes ...
Carbon-14 is more unstable than carbon-12, so it's radioactive: it naturally disintegrates, giving off subatomic particles in the process, to turn itself into nitrogen. Carbon-12 and carbon-14 are called isotopes of carbon. An isotope is simply an atom with a different number of neutrons ...
An atom is a microscopic particle made up of even smaller protons, neutrons, and electrons. All the electrons are arranged in a definite pattern of distribution called the electronic configuration. The chemical reactivity of an atom is directly related to its valence shell electronic configuration....
What is the charge of an up quark? Is a quark smaller than an atom? What is a lepton? What is subatomic particle physics? What is the force between an up quark and a down quark? What particles are outside the nucleus of the atom? What do quarks have to do with radioactive decay?
Quarks are fundamental particles, also known as elementary particles, that form composite particles located in the nucleus of the atom. They can also combine with antiquarks to form mesons.Answer and Explanation: An up quark is a type of elementary particle that binds with other quarks to form...
All matter consists of atoms, which, in turn, consist of protons, neutrons and electrons. Both protons and neutrons are located in the nucleus, which is at the center of an atom. Protons are positively charged particles, while neutrons are neutrally charged. Electrons are negatively charged, ...
is called the “photoelectric effect.” During this process, if the primary x-ray had sufficient energy, electrons are ejected from the inner shells, creating vacancies. These vacancies present an unstable condition for the atom. As the atom returns to its stable condition, electrons from the ...
Beta decay is the most common form ofradioactive decay. It happens in one of two ways. In one type of beta decay, an unstableatomic nucleusemits anelectronand an antineutrino while converting a neutron to a proton. In the second type, the unstable nucleus emits a positron (a positively ch...
A bit is a tiny section of a computer that either holds an electrical charge (1) or does not hold an electrical charge (0). A qubit is the uncertain, unstable position of an electron within an atom. What are the challenges of building quantum computers? To this point, very few quantum...
The atom is the smallest unit on Earth. It is the basic component of any type of matter. It cannot be broken down or sectioned. Protons, neutrons and electrons make up the subatomic particles of an atom. The three subatomic particles determine the overa
