Where do you find an element’s mass, its isotopes or the answer to a homework question, all in one place? Right here. Atomic is a periodic table with everything about all 118 elements behind it, plus tools and an assistant for when you get stuck. This guide shows you the four places you’ll use most.
1. The periodic table
When you open Atomic, the first thing you see is the periodic table: all 118 elements in the official IUPAC layout. Every square is one element. Rows are called periods and columns are called groups; Guide 4 explains why they’re arranged that way.
The table can also show more than names. Switch the data it displays and every square shows that value instead, such as atomic mass, electronegativity or density. Patterns that are hard to spot in a list become obvious when they’re spread across the table.
Tip: Pinch to zoom on a phone, and turn your phone sideways to see the whole table at once.
2. Element pages
Tap any element to open its page. This is where Atomic keeps everything it knows about that element, grouped so you can find what you need quickly:
- The basics: name, symbol, atomic number, atomic mass, group and period
- Atomic properties: electron configuration, electronegativity, atomic radius
- Thermodynamic properties: melting point, boiling point, state at room temperature
- Electromagnetic and nuclear properties: for when your studies go further
Are there elements you look up all the time? Add them to your favourites, and their key data will show at the top of every element page.
3. Tables and tools
Some data is easier to compare across many elements at once, so Atomic also has its own tables and tools:
| Tool | Use it when you want to… |
|---|---|
| Isotope table | See every known version of an element and how its neutron count varies |
| Ionisation energies table | Compare how hard it is to remove electrons from different elements |
| Formulas table | Look up common formulas used in chemistry and physics |
| Nuclide table | Explore stable and radioactive nuclei |
| Molar mass tool | Type a formula like H₂SO₄ and get its molar mass at once |
At this stage you don’t need to know what any of these terms mean. Later guides introduce each tool when it becomes useful.
4. Ask Atomic
You don’t always know which table holds the answer you need. Ask Atomic is the built-in chemistry assistant: type a question in plain words and it will find the data for you or guide you through a problem.
You can ask it things like:
- “What is the boiling point of nitrogen?”
- “Which element has the highest electronegativity?”
- “Quiz me on the noble gases”
Ask Atomic works from Atomic’s own element data, which means its answers stay grounded in the same numbers you see on the element pages. If an answer looks surprising, open the element page to check it: a good habit with any tool.
Try it in Atomic
- Open the table and tap gold (Au). Find its atomic number and melting point.
- Add gold to your favourites.
- Switch the table to show electronegativity. Which corner of the table has the highest values?
- Open the molar mass tool and enter H2O.
Ask Atomic
- “What is gold used for?”
- “Why is helium a gas at room temperature?”
