∙ 14y agoTo calculate the number of neutrons in an atom, subtract the atomic number from the atomic weight. That will give you the number of neutrons. The atomic number is the number of protons. The atomic weight consists of the number of protons plus the number of neutrons. (The electrons add very little to the atomic weight.)

∙ 13y ago(Atomic weight and Atomic Mass is the same thing)
so
find the atomic mass of the element on the Periodic Table
subtract that by the number of protons (aka the element number) of that element.
that is the number of neutrons :)

How many protons (p) neutrons (n) and electrons (e) are in an atom of calcium?
There are 20 p , n , e- in an atom of calcium. Its atomic number is also 20.
What equals the number of neutrons plus the number of protons in an atom?
The mass number is a whole number that is equal to the sum of protons and neutrons in an atom. Mass number is represented by the letter (A) orA= Z + N (Z) represent the atomic number or the number of protons in the nucleus.
What is the number of protons neutrons and electrons nitrogen?
A nitrogen atom has 7 protons, 7 electrons and 7 neutrons for the most common isotope
How many electrons can have the quantum number n equals 7 in an atom?
14:7 neutrons and 7 protons
How many protons neutrons and electrons are in an atom of calcium-42?
Calcium has atomic number 20, which means that all calcium atoms have 20 protons in their atomic nuclei. Neutral calcium atoms also have 20 electrons. Isotopes of calcium vary in the number of neutrons in their atomic nuclei, and are named for their mass number, which is the sum of the protons and neutrons in the nucleus. You can calculate the number of neutrons (N) in an isotope by subtracting the number of protons (atomic number) from the mass number. N = 42 - 20 = 22, therefore, a calcium-42 isotope has 20 protons, 20 electrons, and 22 neutrons.
N atom has 7 protons and a mass number of 14 What is the number of neutrons in an atom of N?
Unless N is a isotope it will have the same amount of neutrons as protons
What does the equation N equals A-Z mean?
N represents the number of neutrons in an atom, A represents the atom's mass number and Z is the atoms proton number. This makes sense because it shows that the mass number of an atom is the number of protons added to the number of neutrons in the nucleus.
What is number of neutron of N?
There are seven (7) neutrons in each atom of nitrogen (N).
What is atomic mass A and neutron number N for given atom?
Atomic mass is the number of protons and neutrons that make up an atom. The neutron number is only the number of neutrons present in the atom. This can be found by subtracting the number of protons from the atomic mass.
What number of neutrons would make a nitrogen atom most stable?
Nitrogen has two natural isotopes: N-14 with 7 neutrons and N-15 with 8 neutrons.
What is the relationship between istotopes mas number and neutrons?
atomic mass of an atom = number of neutrons + number of protons For example the Deuterium isotope of Hydrogen Atomic mass number = 2 Atomic number = 1 The atomic number is the same as number of protons, so the Deuterium isotope has 1 proton atomic mass of an atom = number of neutrons + number of protons 2 = n + 1 n = 1
What is the definition of the isotope xenon?
Xe-n where n is a number which represents the number of nucleons in the atom of the isotope. n can vary between 124 and 136.
How many protons (p) neutrons (n) and electrons (e) are in an atom of calcium?
There are 20 p , n , e- in an atom of calcium. Its atomic number is also 20.
Atomic mass equals the number of what?
The atomic mass NUMBER equals the number of protons and neutrons in an atom. DO NOT confuse this with the mass of an atom.
What equals the number of neutrons plus the number of protons in an atom?
The mass number is a whole number that is equal to the sum of protons and neutrons in an atom. Mass number is represented by the letter (A) orA= Z + N (Z) represent the atomic number or the number of protons in the nucleus.
An atom with a mass number of 45 has three more neutrons than protons What is the atomic number of this atom?
The atomic number is 21: The mass number is the sum of protons and neutrons, while the atomic number is the number of protons, designated n. From the statement of the problem, n+n+3 = 45, or 2n = 42, or n=21.
What is the number of protons neutrons and electrons nitrogen?
A nitrogen atom has 7 protons, 7 electrons and 7 neutrons for the most common isotope
