What is the pH of a solution
A measure of the acidity of a solution
The principal quantum number for the outermost electrons in a Bromine atom in the ground state is
It is n=4 because Br is in the 4p valence shell.
What is the nuclear decay equation for an example of alpha decay
The equation for the alpha decay of 239Pu is: 94239Pu --> 92235U + 24He
where 24He represents the alpha particle, which is a Helium nucleus.
