The atomic level is the finest grain of aggregation summarized by a dimensional data model. When applied to dimensions, the atomic level refers to the discrete values the dimension may assume. When applied to a dataset, the atomic level is the cell created by the intersection of all dimensions at the atomic level. The atomic level is the lowest level of detail normally stored in a multi-dimensional database.
For hydrogen (atomic number 1), there is 1 electron in the first energy level. For helium (atomic number 2), there are 2 electrons in the first energy level. For lithium (atomic number 3), there are 2 electrons in the first energy level and 1 electron in the second energy level. For beryllium (atomic number 4), there are 2 electrons in the first energy level and 2 electrons in the second energy level. For boron (atomic number 5), there are 2 electrons in the first energy level and 3 electrons in the second energy level.
At the atomic level, energy can be observed through the movement and interactions of particles such as electrons, protons, and neutrons. Processes such as electron transitions between energy levels, nuclear reactions, and electromagnetic interactions contribute to the observed energy manifestations. These atomic-level activities involve the exchange, conversion, and release of energy in various forms.
A neutral atom with an atomic number of 15 (phosphorus) will have 5 electrons in its outermost energy level. This is because the atomic number tells us the number of protons, which is equal to the number of electrons in a neutral atom. The outermost energy level for phosphorus is the third energy level.
Atomic number 10 corresponds to neon. Neon has 10 electrons, with 2 electrons in the innermost energy level and 8 electrons in the outermost energy level.
The first theory to relate chemical changes to events at the atomic level was proposed by John Dalton in the early 19th century. Known as Dalton's atomic theory, it stated that elements are composed of indivisible particles called atoms, and chemical reactions involve the rearrangement of these atoms to form new substances.
The atomic level is unchanged.
Electricity begins at the atomic level.
because the iron and oxygen have combined on an atomic level creating the compound iron oxide and you would need to manipulate it on the atomic level to separate it.
Atomic energy level diagrams can be found online at Wikipedia and Hyperphisics. The local library may also be a good place to find examples of an atomic energy level diagram.

Temperature at the atomic level is a measure of the average kinetic energy of the particles in a system. It reflects how fast the particles are moving or vibrating.
