An atom of atomic number 53 and mass number 127 has how many neutrons?

because neutrons and electrons weight nearly the same, and electrons have such little mass that they are virtually insignifigant, the amount of neutrons can be found by subtracting the protons from the total weight.
total weight-protons=neutrons(roughly)
so in this case, the cobalt (atomic # 27) has 28 neutrons

∙ 12y agoBecause the number of protons, not neutrons, determines the atomic number for each specific element, there is no single answer.
A number of elements have isotopes with 53 neutrons, including
106I (iodine)
93Zr (zirconium)
95Mo (molybdenum)
and the synthesized elements 94Nb (niobium) and 96Tc (technetium).
To find the number of neutrons, subtract the atomic number from the mass number. For an atom of atomic number 53 and mass number 127: 127 (mass number) - 53 (atomic number) = 74 neutrons.

∙ 14y agoTake atomic number from Atomic Mass in order to get the number of neutrons present.
121 - 51 = 70

How do you tell how many neutrons are in an atom with the atomic number of 12?
To find the number of neutrons in an atom with an atomic number of 12 (which is the number of protons), you would subtract the atomic number from the atomic mass number. The atomic mass number is the sum of the protons and neutrons in the atom. For an atom with an atomic number of 12, the number of neutrons can be calculated by subtracting 12 from the atomic mass number given for that specific atom.
How many neutrons does an atom of 21Ne have?
An atom of 21Ne has 11 neutrons. This is determined by subtracting the atomic number (which is 10 for neon) from the atomic mass number (which is 21 in this case).
How many neutrons are there in an element having a mass number of 155 and an atomic number of 63?
To calculate the number of neutrons, subtract the atomic number from the mass number. In this case, for an element with a mass number of 155 and an atomic number of 63, the number of neutrons would be 92 (155 - 63 = 92).
How many protons and neutrons are there in an atom of 5B11?
In an atom of ^11B5, there are 5 protons and 6 neutrons. This is because the atomic number (5) specifies the number of protons, and the atomic mass (11) minus the atomic number gives the number of neutrons.
How many protons and neutrons are there in the nucleus of an atom that has an atomic number of 84 and a mass number of 210?
The atom has 84 protons (atomic number) and 126 neutrons (mass number - atomic number).
How do you figures out how many neutrons are in an an atom?
Finding out how many neutrons are in a atom is easy. All you have to do is find the element's atomic number and atomic weight.
How many neutrons are in one atom in fluorine?
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.
How do you figure out how many neutrons are found in an atom?
Finding out how many neutrons are in a atom is easy. All you have to do is find the element's atomic number and atomic weight.
How do you find out how many neutrons a atom has?
Mass number = Atomic number (or number of protons) + Number of neutrons
If an atom has the atomic number of 4 and the atomic mass of 9.012 how many electrons will it have?
Atomic mass is protons + neutrons, and the atomic number (4) gives you the number of protons. Thus, this atom would have 5 neutrons.
How many neutrons does Krytpon-82 have?
The answer to how many neutrons an atom of an isotope has is always the difference between the mass number of the isotope and the atomic number of the element. The atomic number of krypton is 36. Therefore, an atom of krypton-82 has 46 neutrons.
If an atom has an atomic namber of 20 and a mass namber of 53 how many protons and neutrons does that atom have?
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.
How many neutrons are in an atom with the mass number being 186?
The atomic number (number of protons) of the element is needed to tell the number of neutrons. Mass number = atomic number + number of neutrons.
How is an atomic number similar to mass number?
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".
What does an elements atomic number represent-?
The number of protons (or electrons) an atom has. To find out how many neutrons there are take the atomic number and subtract it from the Atomic Mass... (atomic mass)-(atomic number)= neutrons atomic number= #of protons (or #of electrons)
What does the atomic number of an element tell you about its atom?
It would tell you how many neutrons make up the Nucleus of the atom.
How many neutrons does an atom of U-251 have?
Number of neutrons = Mass number - Atomic number = 251 - 92 = 159
