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 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.
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
The subscript in a chemical formula represents the amount of that atom in that compound's formula.
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 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.
Isotopes have the same amount of protons but a different amount of neutrons.
Number of protons + Number of neutrons = Mass number(number of nucleons)
If the chemical element has isotopes the number of neutrons is different for each isotope.
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.
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.
There are several such elements. Examples are helium and carbon.
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.
There isn't a formula for finding joules. It is a way for finding a force or giving an example.
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.
Yes, isotopes of an element are the same element but with different numbers of neutrons in the nucleus and thus different atomic masses.
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).
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.
