How do you find the neutrons of an element using only the atomic number?

You can't. You can narrow it down a bit---most stable elements have a neutron-to-proton ratio of between 1.5:1 and 1:1 (depending on size). So if you know how many neutrons an element has you can make an educated guess as to approximately how many protons it will have. However, it is impossible to know exactly how many protons an element has based on its number of neutrons, and since the number of protons determines the element's identity, you cannot learn an element's identity from its number of neutrons. For example---all of the following isotopes can be formed with 7 neutrons, with stable ones bolded and underlined: He-9, Li-10, Be-11, B-12, C-13, N-14, O-15, F-16, Ne-17, Na-18, and Mg-19.

∙ 14y agoIt cab be found by following ways
No. of Neutron= Atomic Mass - Atomic Number
i.e subtracting atomic number from atomic mass

∙ 11y agono you may not different atoms may have the same number of neutrons because of isotopes a common example Carbon14 has 8 neutrons, oxygen16 also has 8 neutrons.

How do you find the number of neutrons in a element using only mass and the element name?
Look up the name on the periodic table and subtract the atomic number from the mass number (which is protons and neutrons). That will give you the number of neutrons.
What is an isotope and how is it determined?
An isotope is any of the atoms of an element with different numbers of neutrons. It is determined by using the atomic weight,which is determined by the number of neutrons.
Can you identify an atom without knowing number of neutrons in it?
Yes, and in order to find the Number of Neutrons, subtract Atomic Mass from Number Of Protons, the result will be the Number of Neutrons for that atom *No. Of Neutron=Atomic Mass - Number Of Protons
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
What two things does the atomic mass represent?
Atomic mass is the sum of the number of protons and neutrons in the nucleus. The reason it is typically found in decimal form is because it is using the average number of neutrons, from all the different isotopes of that element.

How are the number of protons and neutrons in an atom determined using the periodic table?
The proton number is the same as the atomic number of the element, which can be found from the periodic table. The number of neutrons can be found by subtracting the atomic number from the mass number given for the isotope in question.

Where are the nuetrons found on the periodic table?
Neutrons are sub-atomic particles. The Periodic Table is an arrangement of the elements (atoms) made from these subatomic particles. Thus Neutrons by themselves have no place in the Periodic Table. However as all elements/atoms (except Hydrogen) contain some Neutrons, it is possible to find out how many using the information presented on the Periodic Table. The number of Neutrons present in an element/atom can be determined by subtracting the atomic number of an element/atom from its atomic mass.

What information about an element can you find on the periodic table of elements?
Using a periodic table, you can find an element's name, symbol, atomic mass, and atomic number. The atomic number tells you how many protons and electrons are found in the element. By subtracting the mass number by the atomic number, you can find the number of neutrons prevalent (varying in specific isotopes).
How do you get the number of neutrons in a element?
To find the number of neutrons in an atom you would subtract the protons from the atomic mass. The number of protons is equal to the atomic number. When dealing with an element with no net charge, the atomic number = the number of protons and also the number of electrons. The atomic mass - the atomic number (number of protons and electrons) = the number of neutrons
How many neutrons are in the nucleus of the isotopes of aluminum-25?
The atomic number of aluminum is 13, therefore there will be 13 protons.The number of neutrons equals the mass number minus the atomic number. For aluminum-25, that will be 25 - 13 = 12 neutrons.There will be 13 electrons in the neutral atom of aluminum, regardless of which isotope we are considering.
How you can use an atomss mass number and atomic number to determine the number of protons electrons and neutrons in the atom?
number of protons and electrons present in an element is equal to the atomic number of that element while number of neutrons is equal to mass number - atomic number/number of protons/number of electrons.
How do you find how many protonsneutrons and electrons are in an atom?
Using the periodic table you are able to determine the number of protons, electrons, and neutrons for any of the elements identified to this date. Knowing an element's name or symbol, look up the element in the table. For example lets look up Boron! Boron's chemical symbol is B, and from the periodic table its atomic number is 5. The atomic number of an element reveals the number of protons and also the number of electrons the element has as a single isolated atom. Although, the element may not exist freely as an isolated single atom in nature. So, Boron has 5 protons and 5 electrons. The number of neutrons an element may have can vary, and this is what differentiates stable and unstable isotopes of many elements. Boron has a molar mass of 10.811, and is listed with two stable isotopes: 10B and 11B. Subtracting the atomic number from the isotope number gives the number of neutrons boron is found with. The 10B isotope has 5 neutrons, and the 11B isotope has 6 neutrons. Since the molar mass is 10.811, we can tell that the 11B isotope is more abundant than the 10B isotope. If the distribution was equal then the molar mass would be 10.5.
