How many protons does an atom of sodium 25 have?
This tells us that sodium has
11 protons
and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass).
How many neutrons are in 25 atoms of sodium?

How many protons are in an isotope of sodium with a mass number of 24?
Isotopes are atoms of the same element containing the same number of protons and electrons but different numbers of neutrons. There are 300 naturally occurring isotopes. Sodium, for example, has 2 isotopes. The atoms of both isotopes contain 11 protons, but sodium-23 has 12 neutrons whereas sodium-24 has
13
.
What element has 30 protons and 34 neutrons?
Zinc
is the first element of the twelfth column of the periodic table. It is classified as a transition metal. Zinc atoms have 30 electrons and 30 protons with 34 neutrons in the most abundant isotope.
