At very large values of r, the electron probability density is very small but not zero.
As the distance from the nucleus increases, the probability of finding an electron decreases but not zero.

The frequencies of these X-rays are unique to each element, and they increase uniformly in successive elements. Moseley found that the square roots of these frequencies give a straight line when plotted against Z; this enabled him to sort the elements in order of increasing atomic number.
What's the relationship between the square root of the frequencies of the X-rays to the number of protons? Like how are they related? What's the reason behind their correlation?

by-product of the decay of other radioactive elements.
How does the decaying of other radioactive elements result to other isotopes? Does the protons disintegrate or separate in order to form another element?

twenty-three of them (including beryllium and fluorine, shown in the table) are monoisotopic
TRIVIA! 23 are monoisotopic!
These elements are: Be, F, Na, Al, P, Sc, Mn, Co, As, Y, Nb, Rh, I, Cs, Pr, Tb, Ho, Tm, and Au. In addition, two elements, Bi and Pa, have only one isotope that contributes to the standard atomic weight, but that isotope is radioactive.<br> Source: https://ciaaw.org/monoisotopic-elements.htm
