The difference between the mass number and the atomic number of an atom tells you how many neutrons the atom contains. For example, Plutonium 239 is element number 93. If you take away 93 from 239 you have 146 left. That tells you that Plutonium 239 has 146 neutrons. That fact creates nuclear explosions!

What following statement best describes the number of neutrons in an atom?
it's equal to the difference between atomic number and atomic mass number
What is the relationship between the number of protons and the atomic number?
atomic number(Z) = no. of protons Detailed: The number of protons in a neutral atom is equal to the number of electrons in the same atom. And the number of electrons in an atom is equal to its atomic number.
The number of neutrons are equal to to the?
Typically to find the number of neutrons, you first round the atomic mass to the nearest whole number. After that to you subtract the number of protons (which is the same as the atomic number) from the newly rounded atomic mass and the resulting number is the number of neutrons. lets use Carbon for example: Atomic mass: 12.01 Atomic mass rounded: 12.00 Number of Protons (same as atomic number): 6 (Rounded atomic mass - number of protons)=6 So Carbon has 6 neutrons. Hope that is easy enough to understand.
How do you calculate how many neutrons there are in an atom?
The number of neutrons in an atom is easily calculated by taking the mass number and subtracting the atomic number. Take for example, Uranium: the mass number on the periodic table is 238, while the atomic number is 92. Take the difference of 238 and 92 and that will be equal to the number of neutrons. 238-92=146
Atomic number is equal to?
no of the protons or the no of electron is equal to the atomic no denoted by the symbol Z
What best describes the number of neutrons in an atom?
It is equal to the difference between atomic number and Atomic Mass number. A+
What is the number of neutron is equal to?
The number of neutrons of an isotope is the difference between the mass number of the isotope and the number of protons (equal to atomic number).
What following statement best describes the number of neutrons in an atom?
it's equal to the difference between atomic number and atomic mass number
Is the difference between the mass number of an isotope and its atomic number is equal to the number of nucleons in the nucleus?
It is equal to the number of neutrons in the nucleus, not nucleons (which include both protons and neutrons.)
What statement best describes the density of an atom's nucleus?
The density of the nucleus is 1000's times the density of the entire atom.
What is the relationship between the atomic number and the electrons in neutral atom?
In a neutral atom the number of protons is equal to the number of electrons. And by definition the atomic number of an atom is equal to the number of protons in it. So the atomic number of a neutral atom is equal to the number of protons or the number of electrons in the atom.
What atomic particle is equal to its atomic number?
The number of protons is equal to the atomic number of an atom
What is the atomic number also equal to?
The atomic number is equal to the protons and electrons of an element.
What number represents the difference between two equal fractions?
There is no difference in value between "equal" fractions: the difference is zero.
What is the relationship between the number of protons and the atomic number?
atomic number(Z) = no. of protons Detailed: The number of protons in a neutral atom is equal to the number of electrons in the same atom. And the number of electrons in an atom is equal to its atomic number.
Translate the difference between twice a number and four time the sum of the number and seven is equal to two?
The difference between a number x and twice y is equal to fifteen.
Atomic number in the atomic nucleus?
The atomic number is equal to the number of the protons in the atomic nucleus.
