50 and 69
Neon has 10 protons and 9 neutrons.
All the isotopes of uranium contain 92 protons; the number of neutrons is variable for each isotope: Number of neutrons = Atomic weight of the given isotope - 92
21 protons and 24 neutrons in the only stable for. But there can be as few as 15 and as many as 39 neutrons.
An atom of Vanadium (V) has 23 protons since it is the 23rd element on the periodic table. To find the number of neutrons, you subtract the atomic number (23) from the atomic mass of Vanadium, which is approximately 50.94. This gives you approximately 28 neutrons in an atom of Vanadium-50 (50V).
Oxygen is a p block element. It has 8 protons and neutrons.
Each element has a different number of protons and neutrons. So it changes for each element.
The number of protons determine what element it is, the number of neutrons determine what isotope it is.
Boron has 5 neutrons and 5 protons for its most common isotope
An element with an atomic number of 80 is mercury (Hg). Mercury has 80 protons and approximately 121 neutrons in its most common isotope, mercury-201 (since 201 - 80 = 121 neutrons).
Unundeptium has 117 protons and electrons; the number of neutrons is 176 or 177, depending on the isotope.
In a regular sample of the element of gold, meaning no change done to it, then there will be 79 protons and 118 neutrons
P-31 has 16 neutrons and 15 protons
