What is the formula for finding the amount of neutrons in an element?

The number of neutrons equals the atomic mass (MA) minus the atomic number (XA). (#neutrons=MA-XA). The neutrons can be calculated in this manner because neutrons hold significant mass in the atom. The molar mass featured for a particular element in periodic tables is actually the average of the atomic masses of the elements' numerous isotopes (elements with extra neutrons than normal). So, by subtracting this mass by the atomic number (the number of protons), you will get a value that is very close to actual number of neutrons for that average element.

The formula for finding the amount of neutrons in an element is: Number of neutrons = Atomic Mass number - Atomic number. The atomic mass number represents the sum of protons and neutrons in the nucleus of an atom, while the atomic number represents the number of protons. Subtracting the atomic number from the atomic mass number gives you the number of neutrons.

**Note that the number of protons is the same as the number of electrons as well as the atomic number.

What is the smallest amount of an element that still retains the characteristic of that element?
The atom is the smallest particle of an element that retains it's characteristics. Sub-atomic particles such as protons, neutrons and electrons form the atom and it is the amount of each of these sub-atomic particles that make the element that element.
What does a subscript show in a chemical formula?
A subscript in a chemical formula indicates the number of atoms of an element in a molecule. It is written as a small number to the right of the atomic symbol.
Are hydrogen -3 and helium -3 isotopes the same element?
Yes, hydrogen-3 (tritium) and helium-3 are isotopes but they are not the same element. Hydrogen-3 has one proton and two neutrons, while helium-3 has two protons and one neutron.
The formula of neutron?
The formula for a neutron is n. Neutrons are subatomic particles with no electrical charge and a mass slightly greater than that of a proton. They are found in the nucleus of an atom.
What is the number of protons and neutrons called?
The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is). The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope. The number of protons and neutrons added together is called the atomic mass.
How are all isotopes of a single element different?
Isotopes have the same amount of protons but a different amount of neutrons.
What is the name number tells you the amount of protons and neutrons in an element?
The mass number tells you the amount of protons and neutrons in an element. It is the sum of protons and neutrons in the nucleus of an atom.
Is it true that atoms of the same element have the same amount of neutrons?
If the chemical element has isotopes the number of neutrons is different for each isotope.
What is the smallest amount of an element that still retains the characteristic of that element?
The atom is the smallest particle of an element that retains it's characteristics. Sub-atomic particles such as protons, neutrons and electrons form the atom and it is the amount of each of these sub-atomic particles that make the element that element.
What makes any element that specific element?
The Atom consists of a certain amount of electrons, protons and usually neutrons. The amount of each of these sub-atomic particles is what makes an element that specific element. Actually, it is only the protons. The number of neutrons and/or electrons can vary, and it is still the same element. The one thing that makes an element that specific element is only the number of protons.
What is the formula for finding joules?
The formula for finding joules is: Joules = Force x Distance. This formula is used to calculate the amount of energy transferred when a force is applied over a distance.
What are the differences between isotopes isomers and ions?
Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. Isomers are molecules with the same chemical formula but different arrangements of atoms. Ions are atoms or molecules that have gained or lost electrons, resulting in a net positive or negative charge.
What element has the same amount of neutrons and electrons?
There are several such elements. Examples are helium and carbon.
What is the smallest unit of an element that maintains of that element?
An atom is the smallest unit of an element that maintains the properties of that element. Each atom consists of a nucleus containing protons and neutrons, surrounded by electrons that determine the element's chemical behavior.
Isotopes are forms of the same element that differ in what?
Yes, isotopes of an element are the same element but with different numbers of neutrons in the nucleus and thus different atomic masses.
What formula is Q equals mcpdeltaT?
q is the amount of heat.. that formula is used in finding heat problems
Is it true The number of neutrons in an atom is referred to as the atomic number of that element?
No, the atomic number refers to the protons of an atom, and for the most part the electrons. The atomic mass refers to the neutrons of an element in a way; the atomic mass consists of protons and neutrons, so if you subtract the amount of protons from the atomic mass, you get the amount of neutrons. For example oxygen has an average atomic mass of 16.01 and has 8 protons, so 16.01 atomic mass-8 protons=8.01 average neutrons. Now this is just for the average amount of neutrons, which is changed by isotopes (atoms with different amounts of neutrons).
