Dinitrogen tetroxide has 2 nitrogen atoms and 3 oxygen atoms. Nitrogen has 7 protons and oxygen has 8 protons. So this compound has 38 protons.Oxygen atoms have eight protons each. Nitrogen atoms have seven protons each. So, the given compound has 7x2 + 8x4 = 46 protons.
The atomic number is equivalent to the number of protons or electrons (in the neutral state of an atom).
The total amount of protons and neutrons in an atom is its mass number.
Answer 1The mass number of a nuclide is the sum of the mass of the protons and neutrons in the nucleus. Protons and Neutrons have a mass of approximately 1 atomic mass unit (electrons are not included since the mass relative to the mass of a proton and neutron is to small to count in the total mass. The atomic number of an atom corresponds to the number of protons in the nucleus, and that is the difference.Answer 2Mass number is the total number of protons and neutrons in the nucleus of an isotope. Atomic number is the total number of protons in the nucleus of each atom of an element.
atomic mass number - protons = number or neutrons

mass number = protons + nuetrons
the total number of protons and the total number of electrons in the atom
The atomic number is equivalent to the number of protons or electrons (in the neutral state of an atom).
Mass number is about the neutrons and protons. The total of neutrons and protons.
mass number = protons + nuetrons
Mass number will help you. Mass number is the total of neutrons and protons.
The total amount of protons and neutrons in an atom is its mass number.
The number of protons in the nucleus of its atoms.
The total number of protons in the compound, including both protons from the hydrogen atoms (Ha and Hb), is 6.
