The number of electrons in an electrically neutral atom is also equal to the atomic number, Z. The total mass of an atom is determined very nearly by the total number of protons and neutrons in its nucleus. This total is called the mass number, A. The number of neutrons in an atom, ...
If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons?Answer and Explanation: The atomic number is equal to the number of protons in an atom. For ...
The numbers of electrons in an electrically neutral atom is also equal to the atomic number, Z. The total mass of an atom is determined very nearly by the total number of protons and neutrons in its nucleus. This total is called the mass of the number, A. The number of neutrons in ...
