The PeriodicTableElements is an elegant app that is interactive and fun. Easy to use, easy to understand, simple and effective. It shows the periodic table of elements in variety of ways 1) Classic grid with name that is color coded. You can configure it to look however you like. 2) Visually appealing electron distribution. 3) Visually appealing Lewis dot structure. 4) List that can be sorted based on different element properties like group, period, category etc. These awesome periodic tables can be shared by simple double click anywhere on the table. It is possible to copy the periodic table diagrams as high quality SVG xml. Drag your finger on the periodic table canvas to update elements automatically or tap on an element to see more details. Tap on an element and all the rest of the related elements are highlighted. Details of a selected element is shown in a beautifully drawn animated element. Tap on the animated element and you will see more details that can also be shared. Tapping on the list element will navigate you to a page that shows details of the element. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. This is a perfect app if you are a student learning chemistry. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!

Quantum mechanics is a fascinating field that helps us understand the behavior of matter and energy on a microscopic level. One of the most important concepts in quantum mechanics is the idea of atomic orbitals. An atomic orbital is a mathematical function that describes the probability of finding an electron in a particular location around an atom's nucleus. Each electron in an atom can be described by a unique set of four quantum numbers, which determine its energy level, angular momentum, magnetic moment, and spin. The shape of each atomic orbital can be accurately depicted using a formula called spherical harmonics, which creates a visual representation of the electron's probable location around the nucleus. These representations are often shown as a series of dots, each representing a probable location of where an electron might be. The VSEPR (Valence Shell Electron Pair Repulsion) theory, on the other hand, is a model used to predict the geometry of molecules based on the arrangement of electrons in their valence shells. According to this theory, the electrons in a molecule's valence shell repel each other, and their repulsion determines the molecule's shape. The VSEPR model predicts a range of molecular shapes, including linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral. These shapes can be used to predict a molecule's physical and chemical properties, such as polarity and reactivity. This app will provide you these fascinating insights about the nature of how atoms and molecules behave in the real world.

Verdict
The clearest difference is in-app purchases: Periodic at none against Electronify's 2. Electronify's advantage is ads (none vs shown) and update cadence (every 10 days vs every 5 weeks). On price, device support and iOS requirement there is nothing between them.
