Maxthon Kids Browser HD vs Periodic Table 2026

Award-wining and world leading browser company delivers this safe and clean web browser for your kids. You have complete control of your child’s web environment. Instead of trying to infer what is appropriate for your children based on behavior or demographics, Maxthon's Kid Safe browser keeps it drop dead simple: Parents set up a safe web environment by creating a safe list of websites they want to allow their kids to access. (You can use the Kid Safe browser's pre-selected list of award-winning, age appropriate sites or enter your own.) Access to any url from web domains NOT in your safe list will be blocked. That means advertisements, promotions and links to outside sites from a 'safe site' will be blocked, keeping your child's web activity safely within the boundaries you create. Same thing for search results, too. Creating and modifying of the safe-list requires a password you can reset yourself. This extra security will prevent kids from changing the safe-list. Maxthon’s Kid Safe browser includes: -Parental control: parents control and edit the safe-list that your child is allowed to visit. -Password protected for parents: Creating and editing the safe-list requires a password. -Fun, kid-friendly interface: big buttons, bright colors, easy navigation. -Music: Toe-tapping music for the little ones.

Unlock the building blocks of the universe with a modern, interactive periodic table. Designed for students, educators and science enthusiasts, this app turns a static chart into a living reference: tap any element to see its properties, spin its atom in 3D, read its story and hear its name spoken, in nine languages. SCIENTIFIC DETAIL AT YOUR FINGERTIPS Explore all 118 elements, each with 20 properties, compiled from trusted open sources such as Wikipedia and IUPAC: - Physical Properties: atomic mass, density, melting point, boiling point and appearance. - Atomic Structure: full and shorthand electron configurations, atomic radius, covalent radius, crystal structure, lattice constants and lattice angles. - Chemical Behavior: electronegativity (Pauling scale), ionization energy, electron affinity and oxidation states. - Thermodynamics: specific heat capacity. - Identification: atomic number, group, period and category, plus who discovered each element and when. THE STORY OF EVERY ELEMENT Go beyond the numbers. Every element comes with a short introduction covering: - Real-World Uses: from jewelry and electronics to medicine and aerospace. - Production: how the element is extracted or made today. - History: how it was discovered and where its name and symbol come from. - Health and Safety: its biological roles and the precautions to take. - Market and Properties: what drives its price and what makes it distinctive. STUNNING INTERACTIVE VISUALS - 3D Bohr Models: watch the electrons fill their shells, and rotate and zoom with your fingers. - 3D Crystal Structures: turn the lattice to see how the atoms pack together, from body-centered cubic to hexagonal. - Color-Coded Groups: spot alkali metals, transition metals, metalloids, noble gases, lanthanides, actinides and more at a glance. - Full Screen: turn your device on its side to see the whole table at once, ideal for revision or the classroom. HEAR EVERY NAME, IN NINE LANGUAGES Not sure how to say "praseodymium"? Tap the speaker. Every element's name has been recorded in each of the nine languages, so it sounds natural and the same on every device. THE WHOLE APP IN YOUR LANGUAGE Every element name, property and introduction is translated into nine languages, and the app goes by a name in each of them: - Periodic Table (English) - Tabla periódica (Español) - Tableau périodique (Français) - Periodensystem (Deutsch) - 元素周期表 (中文) - Tabela Periódica (Português) - 周期表 (日本語) - आवर्त सारणी (हिन्दी) - Периодическая таблица (Русский) Oxygen becomes Oxígeno, 氧, 酸素 or Кислород, and every name is spoken in its own language. The app follows your device's language, and you can switch at any time in Settings. THE PERFECT STUDY TOOL - Understand Every Number: tap the ⓘ next to any property for a plain explanation. The built-in glossary covers 23 terms with real examples from the table. - 350 Years of Discovery: the history section tells how the periodic table was pieced together, from alchemists to the superheavy elements of today. - Powerful Search: find any element instantly by name, symbol or atomic number, in your own language. - Quick Filters: highlight a whole group with one tap, or tap Ln or An to focus on the lanthanides or actinides. - Works Offline: the table, every element's details, the 3D models and the recorded names are built into the app, so they work without an internet connection. DESIGNED FOR EVERY DEVICE - Built for iPhone and iPad, in portrait and landscape. - A clean, uncluttered design that keeps the elements front and center. - Also available on both the web and mobile platforms. PRIVATE BY DESIGN Free, with no account, no ads, no analytics and no cookies. The app does not collect any personal data. Whether you are preparing for a chemistry exam, teaching a class or exploring the wonders of the natural world, Periodic Table: Interactive 3D puts every element one tap away.
