U.S. Army STARS Elements is a fun and exciting way to learn chemistry. Build your own atom, play a game to help you learn about chemical bonds, explore the periodic table, and test your chemistry knowledge. Elements is great for students, teachers, and anyone interested in chemistry. U.S. Army STARS Elements includes... Atom Builder - A simple, powerful tool that let’s you construct and discover atoms. Add and subtract protons, neutrons, and electrons and see, in 3D, what you can create. SmashBond - Use the octet rule to bond elements and score points in SmashBond. Swap elements to make 2, 3, or 4 element bonds, and grab bonuses to get a SMASHBOND. It’s a really fun way to help you become familiar with the octet rule and learn common chemical bonds by their type, symbol, name and Lewis dot diagram. Periodic Table - Use the table to view trends and detailed information about each of the 118 elements. See an interactive Bohr’s model and learn interesting facts about the elements. It’s like a regular periodic table, but interactive and fun. STARS Challenge - When you’re ready to test your knowledge, take the STARS Challenge. You’ll be presented with questions in 3 areas (elements, bonding, and atomic configuration). Can you master them all? No matter what your level of experience with chemistry, U.S. Army STARS Elements makes learning fun. Easy to use lesson plans and teacher guides are available at http://usarmystars.com/lessons to help integrate Elements into the classroom.

EleMend Periodic Table app is the ideal tool for individuals with an interest in chemistry, science, and the elements. Sporting a user-friendly interface, the app furnishes an abundance of information about each element, encompassing its properties, historical significance, and practical applications. Among the most captivating features of EleMend is its 3D representation of each element. With a mere few taps, users can immerse themselves in the structure of every atom, gaining insight into the arrangement of electrons, protons, and neutrons through a lifelike and interactive experience. This feature breathes life into the elements, facilitating a clearer comprehension of their behavior and characteristics. This Periodic Table app further augments understanding by offering 3D visualizations of orbitals. This novel perspective enhances users' grasp of electron movement within an atom's nucleus. The three-dimensional presentation of these patterns fosters an intuitive understanding of electron distribution across energy levels, which in turn govern an element's chemical properties. A robust asset within EleMend is the emission spectrum feature. This tool allows users to observe the distinct range of colors emitted by an element when subjected to excitation, such as heat or exposure to an electric field. By scrutinizing these colors, scientists can identify unknown elements and glean insights into diverse substances' behaviors. Additionally, the app encompasses a trove of element-specific data, including atomic weight, melting and boiling points, and other essential particulars. Users can perform targeted searches for specific elements or explore by categories like metals, nonmetals, or noble gases. Each element boasts its own dedicated page, replete with comprehensive information regarding its discovery, historical context, and industrial and everyday applications. Irrespective of whether one is a student, educator, or merely intrigued by the natural world, the EleMend Periodic Table app proves an invaluable resource for delving into the elements and the science underpinning them. Leveraging its 3D models, visualizations, and wealth of insights, the app provides a distinctive and captivating approach to unraveling the universe's fundamental building blocks.
