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 ...
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 Beta Decay? 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 pos...
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 ...
A quark is the smallest unit of matter. In an atom, quarks compose the protons and neutrons found in the nucleus. There are six types of quarks but...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your ...
If an atom absorbs a photon of light with enough energy — say an ultraviolet photon from a hot star— this absorbed energy can cause an electron to transition to a higher energy level for a short time. This is an unstable situation, however, so the electron drops back down and as it ...
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, ...
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
This peculiarity is historically at the root of its success in describing energy quantization, which solved the black body spectrum and also the stability of the hydrogen atom. Nonetheless and paradoxically, quantum mechanics is a linear representation of the world, which hints at it being closely ...
