The Number of Protons from Electrons. For a neutral atom, the number of protons and the number of electrons are equal. This is what makes the atom charge-free. Therefore, you can determine the number of protons if the number of electrons is given. For example, identify the element of an atom with 54 electrons.
1 Σεπ 2024 · The atomic number (number at the top) is the amount of protons and the amount of electrons. So if an element has an atomic number of 5, you know that it has 5 protons and 5 electrons. The atomic mass (number at the bottom) is the amount of protons and neutrons added together.
Atom is uniquely identified with the atomic symbol Z. The atomic number is the number of protons present in the nucleus. In the case of uncharged atoms, the atomic number is equal to the number of electrons. In contrast, in ions, the number of electrons is the difference between the atomic number and the charge of ions.
6 Οκτ 2020 · Atomic number (Z) is the number of protons, while atomic mass number (A) is the number of protons plus neutrons. Mass number does not include the mass of electrons because they are negligible compared to the mass of protons or neutrons.
Virtually all the mass of the atom is concentrated in the nucleus, because the electrons weigh so little. The atomic number is also given the more descriptive name of proton number. The mass number is also called the nucleon number. How many protons and neutrons has this atom got?
