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).

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

How many neutrons are there in an element having a mass number of 155 and an atomic number of 63?
The number of neutrons in the nucleus of an atom is always the difference between the mass number of the atom and the atomic number of the atom. Therefore, in this instance, there are (155 - 63) or 92 neutrons in the atom.
How can you determine the number of neutrons in an atom if its mass number and its atomic number are known?
It is impossible to determine the number of neutrons from the mass number and atomic mass, since the two are essentially same value. However, with the atomic number and the mass number, one can calculate the number of neutrons by subtracting the atomic number from the 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)
How do you tell how many neutrons are in an atom with the atomic number of 12?
Mass number is needed to answer this correctly. Mass number = number of protons + number of neutrons
How many nucleons does an oxygen with a mass number of 17 and an atomic number of 8 have?
There are no 'nucleons' in an Oxygen atom. You mean 'neutrons'. As all the mass of an atom is in its nucleus (made up of 'protons' and 'neutrons') and as the Atomic Number is the count of how many 'protons' there are, if you subtract the Atomic Number form the Atomic Mass, you get the number of 'nutrons'. 17-8=9.
How many neutrons are in one atom?
The number of neutrons depends on the atom. In general, mass number = atomic number + number of neutrons.
If the atomic mass of an atom is 48 and the atom contains 20 protons how many neutrons does the atom contain?
28. Atomic mass - Atomic # (same as the number of protons) = number of neutrons
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 do you calculate how many neutrons there are in a atom?
The atomic weight minus the number of protons = the atom's neutrons.
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 are there in an element having a mass number of 155 and an atomic number of 63?
The number of neutrons in the nucleus of an atom is always the difference between the mass number of the atom and the atomic number of the atom. Therefore, in this instance, there are (155 - 63) or 92 neutrons in the atom.
If an Atom has an atomic number of 12 What is the atomic number?
Atomic number depends on the number of protons and it doesn't matter how many neutrons there are in that case. Neutrons only contribute to the atomic weight. The atomic number is the same as any other atom of carbon: 6.
How can you determine the number of neutrons in an atom if its mass number and its atomic number are known?
It is impossible to determine the number of neutrons from the mass number and atomic mass, since the two are essentially same value. However, with the atomic number and the mass number, one can calculate the number of neutrons by subtracting the atomic number from the mass number.
Distinguish between atomic number and atomic mass?
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
