A shell surrounding the nucleus of an atom containing electrons.
Depending upon what the scientist does, and how experienced they are, they can make between $60,000 a year to $200,000+ It is hard to define further than this as "scientist" can be a number of different specific jobs from technicians in research laboratories to the presidents of consulting firms.
Edward Robinson is not primarily recognized as a Jamaican scientist. He was an American archaeologist and biblical scholar known for his work in the 19th century. If you are referring to a different individual with that name or a specific context involving a Jamaican scientist, please provide more details for clarification.
That was Niels Bohr
The scientist who developed the atomic theory of matter was John Dalton. He proposed that matter is made up of indivisible particles called atoms that combine in specific ratios to form different compounds.
Yes, in atomic theory, electrons occupy fixed distances from the nucleus, often described as specific energy levels or shells. Each shell corresponds to a particular energy state and can hold a set number of electrons. While these distances are not fixed in a physical sense, as electrons exist in probabilistic orbitals, they represent regions where electrons are likely to be found at certain energy levels. Thus, the concept of fixed distances is more about energy levels than absolute positions.
The concept of energy levels in atoms was developed by Niels Bohr in 1913 as part of his atomic model. Bohr proposed that electrons orbit the nucleus in specific energy levels, and that they need a specific amount of energy to jump between these levels.
The idea that electrons occupy specific orbits or energy levels around the nucleus was primarily developed by Niels Bohr in his 1913 model of the atom. Bohr proposed that electrons move in defined circular orbits at certain distances from the nucleus, with each orbit corresponding to a specific energy level. This model laid the groundwork for the later development of quantum mechanics, which refined our understanding of electron behavior in atoms.
The Bohr model
Electrons are the components of an atom that are arranged in various energy levels or orbitals. These energy levels are quantized and correspond to different distances from the nucleus, with each level accommodating a specific number of electrons based on their energy.
Electrons can occupy specific energy levels around an atomic nucleus, often referred to as electron shells or orbitals. These energy levels are quantized, meaning electrons can occupy only discrete distances from the nucleus. The most common orbits include the s, p, d, and f orbitals, which can each hold a specific number of electrons.
Electrons are in energy levels because of the principles of quantum mechanics, which dictate that electrons can only occupy specific energy levels within an atom. These energy levels are quantized and represent different distances from the nucleus. Electrons fill these energy levels in order of increasing energy, following the Aufbau principle.
A biologist is a specific type of scientist specializing in Biology. A scientist can be any type of scientist but their specialty is not specified.
Niels Bohr proposed the theory that electrons move in specific energy levels or shells around the nucleus of an atom. This model, known as the Bohr model, was based on his work with the hydrogen atom and was published in 1913.
