1. What Are Atomic Numbers?

The atomic number of a chemical element is the number of protons found in the nucleus of an atom of that element. It uniquely identifies a chemical element and determines its position in the periodic table.

2. How This Calculator Works

This calculator provides a quick lookup of element symbols and names based on their atomic numbers (1 through 118).

How it works: The calculator uses a predefined database of all 118 known elements to match atomic numbers with their corresponding element information.

3. Importance of Atomic Numbers

Details: Atomic numbers are fundamental to chemistry and physics. They determine an element's chemical properties and its place in the periodic table. The periodic law states that the properties of elements are periodic functions of their atomic numbers.

4. Using the Calculator

Tips: Simply enter any whole number between 1 and 118 to see the corresponding element's symbol and name. The calculator will instantly display the result.

5. Frequently Asked Questions (FAQ)

Q1: What's the highest atomic number?
A: As of 2023, the highest confirmed atomic number is 118 (Oganesson). Elements with higher atomic numbers may be discovered in the future.

Q2: Are there gaps in atomic numbers?
A: No, all atomic numbers from 1 to 118 have been filled with discovered elements.

Q3: Why do some elements have symbols that don't match their names?
A: Some symbols come from Latin or other language names (e.g., Au for gold comes from "aurum").

Q4: How are new elements named?
A: New elements are named by their discoverers and approved by IUPAC, often honoring places, scientists, or mythological concepts.

Q5: Can atomic numbers change?
A: No, an element's atomic number is fundamental and never changes. Changing the atomic number would make it a different element.
