Your specific task is atomic number to electron configuration for the first 36 elements. Open the page, drop your input, get the result — typically under a second.
Your goal is calculate ph using the henderson-hasselbalch equation for buffers. Same approach: paste in, get the result, move on. No account, no upload.
Both tools live in the same category, so the choice depends on the exact subtask. e- Config focuses on atomic number to electron configuration for the first 36 elements; H-H Eq focuses on calculate ph using the henderson-hasselbalch equation for buffers. Try whichever description matches your goal more closely — they're both free.
Yes — both tools are free for unlimited personal use. The Pro plan unlocks higher limits and batch features but the core functionality stays free forever.
Absolutely. Many users chain multiple tools together — process a file with one, then feed the result into another. Nothing is uploaded, so chaining is essentially instant.
No. Both e- Config and H-H Eq work without signup. We only ask for an email if you decide to subscribe to a paid plan.
