Einstein informs us that mass-energy is conserved in nuclear fission, therefore the mass of the original atom, in joules per c2, must be the same as the sum of the masses of the daughter particles, in joules per c2, plus the energy released in the fission, in joules.
the total number of protons and neutrons in the nucleus.
The mass number of an atom is equal to the number of protons and neutrons that are in the nucleus of the atom. Atoms are the basic units of a chemical element.
The total number of subatomic particles in the nucleus
The amount of protons and neutrons in the nucleus.
Only if the atom is hydrogen-1! The mass number of the atom is equal to the sum of the numbers of protons, which is the same as the atomic number, plus the number of neutrons. The only non-radioactive atom without neutrons is hydrogen-1.
In a nuclear reaction involving a polonium nucleus, the total charge and total mass number of the products must equal the charge and mass number of the polonium nucleus due to the conservation laws. The charge of the products will match the original charge, and the mass number of the products will be equal to the mass number of the polonium nucleus before the reaction. This ensures that both charge and mass are conserved in the process.
The atomic number of an element is the number of protonsin its atom's nucleus. The mass number of an element is the number of nucleons (protons or neutrons) in its atom's nucleus. Except in the case of hydrogen, which has no neutrons, the mass number will always be higher.
Yes, the difference between the mass number and the atomic number of an isotope equals the number of neutrons in the nucleus, which are also known as nucleons. This relationship helps to identify the number of neutrons in an isotope based on its atomic and mass numbers.
No, the atomic mass is not equal to the atomic number. The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of protons and neutrons in the nucleus. The atomic mass can differ from the atomic number, especially due to the presence of neutrons.
The mass number of an atom is defined as the total number of protons and neutron (collectively called "nucleons") in the atomic nucleus. For example, a helium atom with 2 protons and 2 neutrons would have a mass number of 4.
The mass number of an atom is equal to the sum of its protons and neutrons. It is represented by the letter "A" in the chemical symbol notation, where A = number of protons + number of neutrons in the nucleus of the atom.
No, the number of protons is equal to the atomic number, which is also the same as the number of electrons in a neutral atom. The atomic mass, on the other hand, is the sum of the protons and neutrons in an atom's nucleus.
