What else can I help you with?
How do you determine an atom's mass number?
mass number= no. of protons + no. of neutron
How would you explain how to determine the number of neutrons and atom contains if you know its mass and its atomic number?

What does the mass number determine?
The Number Of Protons & Neutrons In An Atom.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
What is counted in an atom to determine mass number?
The mass number of an atom is determined by counting the total number of protons and neutrons in its nucleus. Electrons, which are much lighter than protons and neutrons, are not included in the mass number calculation.
Mass number used to calculate the number of?
The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.
How do you determine the number of nuetrons in an atom?
Number of Neutrons = Mass number - Atomic Number
Can you use the mass number of an element to determine the number of electrons in an atom?
No, the mass number of an element is the sum of protons and neutrons in the nucleus. To determine the number of electrons, you would need to know the atomic number of the element, which is equal to the number of protons. Electrons in a neutral atom equal the number of protons.
What determine the mass of a atom?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
Is it true that the mass number can be used to determine the number of electrons in an atom?
no --- atomic number
What determine the atom mass?
Essentially an atom's mass is determined by its number of protons and neutrons, as mass of electrons is so minuscule relative the nucleus.
Can the mass number be used to determine the number of electrons in an atom?
No, the mass number (number of protons and neutrons) cannot be used to determine the number of electrons in an atom. The number of electrons in an atom is determined by the number of protons in the nucleus, which is the atomic number. Electrons are equal in number to protons in a neutral atom.
