- Element Symbol: The one or two-letter abbreviation of an element.
- Atomic Number: The number of protons in the nucleus of an atom.
- Atomic Weight: The weighted average of the atomic masses of the element's isotopes.
Frequently Asked Questions (FAQ)
What is the Periodic Table Calculator?
It's a tool that provides detailed information about chemical elements.
How do I use the calculator?
Enter the element symbol or atomic number to get detailed information.
Why are atomic weights not whole numbers?
Because they are averages that account for isotopic distribution.
Can I find element groups using this tool?
Yes, it provides information about the group and period of the element.
Is the data accurate?
All data is sourced from IUPAC, ensuring high accuracy.
