Since n + p = m, it follows that neutrons = 54 - 24 = 30,
because number of protons (p) is the atomic number (34)! That's how the Periodic Table is organized.
To find the number of neutrons, subtract the atomic number from the mass number: neutrons = mass number - atomic number. In this case, for Cr: neutrons = 52 - 24 = 28 neutrons.
The number of neutrons in the nucleus of an element can be calculated by subtracting the atomic number (which is the number of protons) from the atomic mass. For magnesium, the atomic number is 12, and the atomic mass is usually around 24-25. Therefore, the approximate number of neutrons in the nucleus of magnesium is 12-13.
A chromium-54 isotope has 28 neutrons in its nucleus. This is because chromium has an atomic number of 24, which represents the number of protons in the nucleus. Neutrons are calculated by subtracting the atomic number from the mass number.
The atomic number of lithium is 3. Therefor there are 3 protons and neutron in the nucleus of lithium. Lithium also has 4 neutrons. atomic # = protons and neutrons neutrons = rounded atomic mass - atomic number Sources- 7th grade Acc. Science
Californium typically has 20 neutrons in its nucleus.
The atom has 84 protons (atomic number) and 126 neutrons (mass number - atomic number).
The atomic mass number tells how many protons and neutrons are in a nucleus.
Number of neutrons = Mass number - Atomic number = 37 - 17 = 20 neutrons
number of neutrons = mass number - atomic number = 50 - 24 = 26
The atomic number of a chemical element is equal to the number of electrons or protons. The number of neutrons = Atomic weight of an isotope (rounded) - atomic number of the element (or the number of protons)
The Atomic Mass number tells how many protons and neutrons are in a nucleus.
79; the mass number is the sum of the protons and neutrons, and the atomic number is the number of protons. So if you take the mass number (protons + neutrons) minus the atomic number (protons), you get the number of neutrons.
The atomic number of lead is 82. The number of neutrons in an isotope is always the difference between the isotopic mass number and the atomic number. In this instance, 206 - 82 = 124.
Seven. Carbon's atomic number (the number of protons in the nucleus) is 6, so if the atomic weight is 13, there are 7 neutrons in the nucleus. Only 1.07% of all carbon atoms have 7 neutrons; the other 98.9% have 6 neutrons.
If you subtract the atomic number form the atomic mass then the answer is the number of neutrons.
That's Manganese and it has (about) 30 neutrons - - - - BUT your question would have an answer of 11.

Curium is an artificial chemical element. Number of neutrons = Atomic mass of an isotope - atomic number of the isotope The atomic number of curium is 96; and atomic mass is 247 so no of neutrons is 151.
