## Description

K12 Periodic Table of the Elements lets you explore the elements and their key attributes in a simple, easy-to-use way. It's a perfect reference for working through homework problems for Science courses.

Version 3 has these new, advanced features:
* Improved swipe and touch functions display element details such as name, symbol, atomic number, atomic mass, Lewis dots, and radius.

* Colors change in the table to show classification, melting point, boiling point, outermost orbital, radius, ion radius, electronegativity, and ionization energy.

* Temperatures are shown in Kelvin, Celsius, and Fahrenheit scales.

* The table includes the newly named elements Darmstadtium (110), Roentgenium (111), Copernicium (112), and Ununhexium (116).

* Both traditional and expanded views of the table are available on some tablet devices.

* The table matches the style and format of the table in K12's award-winning Chemistry: Problems and Solutions textbook.

Requirements:
* iPhone 3GS or newer with iOS 7+
* iPod Touch 3rd Generation or newer with iOS 7+
* iPad — all versions with iOS 7+

## Review summary

Users praise K12 Periodic Table for being easy to use, information-rich, and great for studying chemistry, with features like Lewis dot structures and customizable displays. However, recurring complaints center on outdated data (missing elements and renamed names), the lack of a search function and poor typo tolerance, inaccuracies in Lewis dot diagrams, and performance issues such as slowness and occasional crashes. UI concerns include an antiquated landscape layout and no auto-rotate. Despite these, many users still regard it as the best quick-reference periodic table app available.

### Pros

- Easy to use with a clean, uncluttered interface that makes studying quick and intuitive.
- Offers a large amount of information about each element, making it a strong reference tool.
- Includes Lewis dot structures and valence electron data for chemistry learning.
- Interactive and customizable display options (toggling table view, drag cursor, etc.).
- Good offline access and quick lookups without needing internet.

### Cons

- Data is not up to date: several missing elements and outdated naming (new elements and renamed names).
- Lacks a search feature and has poor typo tolerance, making element lookup harder.
- Lewis dot structures are reported as inaccurate for some elements, including transition metals and helium.
- Performance issues: app can be slow, laggy, or freeze, and taps may intermittently fail.
- UI/UX problems: landscape layout feels antiquated and auto-rotation is missing, with some views obscuring surrounding elements.
