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.
What else can I help you with?
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.
Are hydrogen -3 and helium -3 isotopes the same element?
no they are not the same element bc isotopes have the same amount of protons but not the same amount of neutrons or electrons! -tabbyg
What does a subscript show in a chemical formula?
The subscript in a chemical formula represents the amount of that atom in that compound's formula.
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.
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.
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?
Number of protons + Number of neutrons = Mass number(number of nucleons)
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 element has the same amount of neutrons and electrons?
There are several such elements. Examples are helium and carbon.
What are the differences between isotopes isomers and ions?
An isotope is an element that has lost or gained neutrons. Isotopes have the same amount of protons and electrons but have a different number of neutrons. The less neutrons the lighter the isotope, the more neutrons, the heavier the isotope. An ion is an element that has lost or gained electrons. Ions have more or less electrons than protons and have a normal amount of neutrons. The more an atom has the more negative it is, the less the more positive it is.
What is the formula for finding joules?
There isn't a formula for finding joules. It is a way for finding a force or giving an example.
What is the smallest unit of an element that maintains of that element?
The Atom is the smallest particle of an element that has characteristics of that 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 into a Atom.
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.
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).
What is the difference between an atom a molecule and an element?
An atom is a nucleus of protons and neutrons with electrons orbiting around. An element is an atom with a specific amount of protons, neutrons, and electrons. A molecule is a bunch of atoms stuck together.
