![“We have here a proof that there is in the atom a fundamental quantity, which increases by regular steps as one passes from one element to the next. This quantity can only be the charge on the central positive nucleus, of the existence of which we already have definite proof.” quote by Henry Moseley](https://sms4smile.com/quotes/i/63c/henry-moseley-63487_atoms_we-have-here-a-proof-that-there-is-in-th_2164114.jpg)   [Download](https://sms4smile.com/quotes/i/63c/henry-moseley-63487_atoms_we-have-here-a-proof-that-there-is-in-th_2164114.jpg) [Open image](https://sms4smile.com/quotes/i/63c/henry-moseley-63487_atoms_we-have-here-a-proof-that-there-is-in-th_2164114.jpg)

> “We have here a proof that there is in the atom a fundamental quantity, which increases by regular steps as one passes from one element to the next. This quantity can only be the charge on the central positive nucleus, of the existence of which we already have definite proof.”

## About This Quote

This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.

Moseley showed that atomic number increases in regular steps, revealing the nucleus charge as the underlying order of elements.

**In simple terms:** Atomic numbers rise stepwise, indicating a central charged nucleus.

Key Takeaway

Recognize atomic number as the key to element order.
