The sum of the protons and the neutrons indicates the .?
By the sum of protons and neutrons we obtain the mass number of the atom which is written at the top of the atom periodic number. We can also obtain the mass number by adding the atomic number and the number of neutrons because the atomic number and the number of protons are same. You know that scientists have discovered some particles which are smaller than protons and neutrons and these are known as quartz.
How do you figure out protons electrons neutrons?
Find the atomic number. That tells you the number of protons and electrons (in a neutral atom). Then find the atomic weight. The number of protons plus the number of neutrons will equal the atomic weight. So if you know the wt. just subtract the number of protons and you will have the number of neutrons.
An isotope is identified by its atomic mass number which is the total number of?
protons and neutrons in the nucleus of an atom. Isotopes of an element have the same number of protons but different numbers of neutrons. The number of neutrons in an atom affects its stability and often determines its nuclear properties.
Is there a relationship between the number of neutrons and protons in the atom is so what type?
Atomic number = number of protons + number of neutrons Mass number = number of protons + number of neutrons
What is the name number tells you the amount of protons and neutrons in an element?
The mass number tells you the amount of protons and neutrons in an element. It is the sum of protons and neutrons in the nucleus of an atom.
how many neutrons in magnesium?
The "25" is the mass number, which is the sum of the number of neutrons and protons. We don't know how many neutrons there are, but we do know how many protons magnesium has. The atomic number of an element is the same as the number of protons, so locating a Periodic Table, magnesium is number 12, which means 12 protons. If mass number = number of protons + number of neutrons, then number of neutrons = mass number - number of protons (or atomic number). So 25 - 12 = 13 neutrons in 25Mg.
The number of protons and neutrons in the nucleus is know as what?
This is the mass number.
How many neutrons are in magnesium 25?
25 is the number of protons and neutrons added together. The atomic number of Mg is 12 which is the number of protons. So 25 - 12 = 13 neutrons.

What does mass do?
The Atomic Mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons

What is the mass number of an atom of iodine with 76 nuetrons?
The mass number of an atom is the sum of protons and neutrons in its nucleus. Given that an atom of iodine has 76 neutrons and typically has 53 protons, the mass number of this iodine atom would be 53 (protons) + 76 (neutrons) = 129.
Is there a relationship between the number of neutrons and protons in the atom is so what type?
Atomic number = number of protons + number of neutrons Mass number = number of protons + number of neutrons

What they do mass number?
Mass number is about the neutrons and protons. The total of neutrons and protons.
