Periodic Table Tutor app is designed to help students memorize the order of electron orbitals filling within the periodic table by prompting for the each successive level of shells. A guide and memory aid is provided at each step to help solidify the student's knowledge of the correct sequence...

Periodic TableGrand Unification TheorySpacetimeDimensionSpherical QuantityPhysical QuantityRecent progress in characterizing electron orbitals within the inert atoms has led to the development of a series of spherical quantities in various space and time dimensions. This indicates intuitively that there are ...
This white-on-black chart shows what atoms look like. This chart shows all the fundamental atomic electron orbitals as electron probability density distributions (fuzzy clouds), which is as close as you can get to visualizing what an atom really looks like. The orbitals are labeled. This elegan...
Elements in similar groups or columns can be categorized together into blocks based on which electron orbital their outermost electrons (i.e., valence electrons) occupy. There are a total of 4 blocks for 4 different electron orbitals: s, d, p, and f. Elements in the same block have their...
Fair enough. But there is debate over which of the elements in the f-block should come first. Some chemists maintain that the decision should come down to electron configuration, which would leave the table as it is, with lanthanum and actinium at the left-hand end of the f-block....
Periodic table - Elements, Groups, Blocks: The periodic table of the elements contains all of the chemical elements that have been discovered or made; they are arranged, in the order of their atomic numbers, in seven horizontal periods, with the lanthano
The different rows of elements are called periods. The period number of an element signifies the highest energy level an electron in that element occupies (in the unexcited state). The number of elements in a period increases as one traverses down the periodic table because as the energy level...
In the periodic table of the elements, elements are arranged in a series of rows (or periods) so that those with similar properties appear in vertical columns. Elements of the same period have the same number of electron shells; with each group across a period, the elements have one more ...
widely used periodic table essentially inherits Pfeiffer's arrangements. Although long-form tables more precisely represent electron orbitals around a nucleus, they lose some of the features of Mendeleev's short-form table to express similarities of chemical properties of elements when forming compounds....
