Can the mass number of an element be used to determine the number of electrons in an atom?
No. The mass number can be used, however, to determine the number of neutrons. Electrons can only be determined by knowing the atom's charge.
The atomic number is determined by?
The atomic mass is the can be determined by the number of protons in an atom. Remember that a proton has an atomic mas number of 1 AMU (atomic mass unit). (The total mass of an atom is the protons, neutrons and electrons combined.)
Why does not an atom of an element represent the actual mass of its atom?
The atomic mass of an element is measured not in the mass of the atom, but in the number of grams per mole.
What is the mass of an atom concentrated on?
virtually all the mass in concentrated in the nucleus of the atom, as the electron's mass is so small, it is negligible.
What is the mass number of a atom?
the mass number is number of protons in an atom, plus the number of neutrons.
What is the partice that determines the mass of an atom?
The atomic mass is mainly determined by the total number of protons AND neutrons.
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.
The volume of an atom is determined by the size of?
By the size of the atom and its mass
What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons
How can an atom's protons be determined?
By the atomic mass
Atomic mass is determined by the number of protons plus the number of?
Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
What is determined the mass of an atom?
Protons, neutrons and electrons
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.
How is the atomic mass determined?
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
Is determined by the number of protons and neutrons in a atom?
Atomic mass.
What is the mass number of 10 protons and 10 neutrons?
20. the mass of an atom is determined by the sum of the number of neutrons and protons the atom has.
Atomic mass of an atom is determined by the combined masses of?
the atomic mass is determined by adding the weight of protons & neutrons
