What else can I help you with?
What does the protons and neutrons tell you about the oxygen atom?
protons will tell the atomic number (8) the sum of protons and neutrons will give the mass number of the element
How many neutrons are in an atom with the mass number being 186?
The atomic number (number of protons) of the element is needed to tell the number of neutrons. Mass number = atomic number + number of neutrons.
What does the mass number tell about an isotope?
The mass number of an isotope tells you the total number of protons and neutrons in the nucleus of that atom. It is used to distinguish different isotopes of an element, as isotopes of the same element have the same number of protons but different numbers of neutrons.
How is the number of neutrons in an atom worked out?
they work because in every atom there is a neutron, electron and proton. the electron will tell you what the atomic number is and the neutrons and protons will tell you what element it is.
How can you tell how many nucleons are in an element?
total number of protons and neutrons in the nucleus.
What does the atomic number tell you about the parts of the element?
The atomic number of an element tells you the number of protons and neutrons that element has. Since an atom has a neutral charge, the number of electrons must equal the number of protons, so you can also tell the number of electrons that element has.
What does an element's mass number tell us?
An element's mass number tells us the total number of protons and neutrons in its nucleus. It helps to determine the element's atomic mass and differentiate it from other isotopes of the same element.
What does the atomic number of an element tell you about its atom?
It would tell you how many neutrons make up the Nucleus of the atom.
Isotopes of an element have a different number of?
neutrons
How do you tell the number of neutrons in an element?
Subtract the atom number from the mass number to get the neutron. Mass number is the sum of neutrons and electrons. Atom number is the number of electrons. the number of electrons is equivalent to the number of protons.
What are the element number of neutrons?
Number of Neutrons = Mass number - Number of Protons
What the atomic mass tell the total number of?
The Atomic Mass of an element tells you what the mass of one mole (6.022 x 1023 atoms) of the element is. It sort of tells you the number of protons & neutrons in the atom, but that is not necessarily precise.
