The atom in question has 13 protons, so is atomic number 13, which is Aluminium. Assuming that all of the atom's mass is formed from the protons and neutrons, and each of these have Atomic Mass 1, the number of neutrons is 27 - 13 = 14 neutrons. Almost all Aluminium is of this isotope.
Mass number is calculated by adding the number of protons to the number of neutrons.
So if an atom has a mass of 27 and 13 of that mass is made up by protons then the answer is:
27 - 13 = 14
So there are 14 neutrons
What is an atom's mass number equal to?
14 27-13
28. Atomic mass - Atomic # (same as the number of protons) = number of neutrons
The atomic weight minus the number of protons = the atom's neutrons.
The Atomic Number of an element is equal to the number of Protons/Electrons in the nucleus and the Atomic Weight is approximately the total number of Protons/Electrons and Neutrons combined. Using Carbon as an example: Total Protons/Electrons = 6, therefore the Atomic Number is 6 Total Neutrons = 6, and the Atomic Weight is 12 Question? The Atomic Number of Lithium = 3 The Atomic Weight of Lithium = 7 How many Protons/Electrons? How many Neutrons? Answer: Protons/Electrons = 3 Neutrons = 4
The nucleus of an atom consists of protons and neutrons. The number of protons in a particular nucleus is its "atomic number". The total number of protons and neutrons in a particular nucleus is its "mass number".
The Atomic Mass tells you how many Protons and Neutrons are in the atom. It is approximately the sum of the number of protons and neutrons found in the nucleus of an atom. Basically the weight of the neutrons and protons in one atom
28. Atomic mass - Atomic # (same as the number of protons) = number of neutrons
The atomic weight minus the number of protons = the atom's neutrons.
Protons and neutrons each have an atomic mass of 1 So, 38-15=23 Neutrons
Atomic mass is protons + neutrons, and the atomic number (4) gives you the number of protons. Thus, this atom would have 5 neutrons.

The nucleus of an atom consists of protons and neutrons. The number of protons in a particular nucleus is its "atomic number". The total number of protons and neutrons in a particular nucleus is its "mass number".
uh, for one thing mass and atomic nUmbers. and the other: it has 20 protons and 33 neutrons. The atom would have 20 protons and 33 neutrons. The number of protons is always the same as the atomic number. To find the number of neutrons, you simply subtract the atomic number from the atomic mass. Atomic mass - Atomic number = number of neutrons (53 - 20 = 33) If you add the number of protons and the number of neutrons together, you should get the atomic mass.
subtract the atomic number by the Atomic Mass, and that is the answer. if its a neutral atom, there are probably the same number neutrons as protons.
There are similar number of neutrons and protons. It contains 29 neutrons and protons.
Americium has 95 protons and electrons. Number of neutrons: Atomic Mass of an isotope - number of protons
The Atomic Mass tells you how many Protons and Neutrons are in the atom. It is approximately the sum of the number of protons and neutrons found in the nucleus of an atom. Basically the weight of the neutrons and protons in one atom
A neutral nitrogen atom has 7 protons, 7 neutrons, and 7 electrons. If it is electrically charged, the number of electrons will be different. If it is an isotope of nitrogen other than the most common (N-14), the number of neutrons will be different. Protons = Atomic Number Neutrons = Atomic Mass - Protons Electrons = Protons Atomic number is the amount of protons in element.
