How do you get the number of Nuetrons on the periodic table?
Look at the atomic mass of the element. Round the atomic mass to the nearest whole number, and subtract the number of protons present in the nucleus (the atomic number). The nucleus of the atom is made of protons and neutrons, so ideally, one can subtract the number of protons or neutrons to get the number of neutrons or protons. So, Lithium would have 4 neutrons, Hydrogen would only have a proton, and Iron has 30 neutrons. Of course, it depends, also, on the isotope of the element, which varies with the number of neutrons. So, carbon-14 would have 8 neutrons and 6 protons, while regular carbon would have 6 protons and 6 neutrons.
What is the mass number for an atom of cobalt that has 33 neutrons?
The mass number for an atom is the sum of its protons and neutrons. Given that cobalt has 27 protons, an atom with 33 neutrons would have a mass number of 60 (27 protons + 33 neutrons).
Do uncombined atoms have the same number of neutrons as protons?
Uncombined atoms have the same number of neutrons as protons only if they are isotopes of the element, which means the atoms have the same number of protons but different numbers of neutrons. Otherwise, atoms with the same number of protons and neutrons would be considered as different elements.
Can an element have the same number of protons and neutrons?
Yes. An example would be carbon-12. It has 6 protons and 6 neutrons.
What is the atomic number for an element with 37 neutrons and a mass number of 72?
The mass number is the amount of protons and neutrons in an element. The atomic number is equal to the amount of protons. Therefore to get the number of protons from the given information, you would subtract 37 from 72 which gives you 35 protons aka its atomic number!
What is the mass number of an atom of cobalt that has 32 neutrons?
The mass number of an atom is the sum of its protons and neutrons. Cobalt has an atomic number of 27, so it has 27 protons. If it has 32 neutrons, then the mass number would be 27 (protons) + 32 (neutrons) = 59.
What is the mass number of 10 protons and 10 neutrons?
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
The mass number of an atom of calcium with 20 protons and 20 neutrons is?
The mass number of an atom is the sum of the protons and neutrons in its nucleus. Therefore, for an atom of calcium with 20 protons and 20 neutrons, the mass number would be 40.
What is the mass number of an iron isotope with 26 protons 31 neutrons ans 24 electrons?
Number of protons + neutrons = mass number 26 protons + 31 neutrons 57
What is the mass number for an atom of cobalt that has 33 neutrons?
The mass number for an atom is the sum of its protons and neutrons. Given that cobalt has 27 protons, an atom with 33 neutrons would have a mass number of 60 (27 protons + 33 neutrons).
Identify the mass number and atomic number of a Chlorine atom that has 17 protons and 18 neutrons?
The mass number is calculated by adding the number of protons and neutrons, so for a Chlorine atom with 17 protons and 18 neutrons, the mass number would be 17 (protons) + 18 (neutrons) = 35. The atomic number is simply the number of protons, which in this case is 17.

What is the mass number of an atom of copper that has 36 neutrons?
The mass number of an atom is the sum of its protons and neutrons. Copper has an atomic number of 29, which means it has 29 protons in its nucleus. If it has 36 neutrons, then its mass number would be 29 (protons) + 36 (neutrons) = 65.
What is the mass number of a magnesium atom with 14 neutrons?
The mass number is the sum of protons and neutrons in an atom. Since magnesium has 12 protons, a magnesium atom with 14 neutrons would have a mass number of 26 (12 protons + 14 neutrons = 26 mass number).
If an isotope of silicon has 15 neutrons what is its mass number?
The mass number of an isotope is the sum of its protons and neutrons. Since silicon has 14 protons, the isotope with 15 neutrons would have a mass number of 14 (protons) + 15 (neutrons) = 29.
How many neutrons are contained in an iodine nucleus with a mass number of 132 and an atomic number of 53?
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.
What is the amount of protons neutrons electrons in oxygen?
8 protons 8 electrons and 8 neutrons. Oxygen has the atomic number 8, so it has 8 protons, 8 electrons. The number of neutrons would be mass number-atomic number, so 15.9994-8=7.9994, so rounding would be 8 neutrons.
