what is the mass number of antimatter counterparts of ordinary atoms? how does the concept of mass number extend to molecules and compounds?

The atomic number is equal to the number of protons found in an atom. B. Neutrons – Neutrons carry no charge and have a slightly larger mass than protons. One atomic mass unit (amu): the mass exactly equal to one-twelfth the mass of one ... Mass number (number of protons plus neutrons). Page 2. Atomic mass = ( ... The atomic number is equal to the number of protons in an atom's nucleus. The atomic mass is the sum of the mass of protons and neutrons. May 26, 2021 ... Step 1: Identify the element. Step 2: Find the number of protons of the element from the periodic table. The number of protons is equal to the atomic number of ... The mass number is equal to the number of protons plus neutrons. In a neutral atom, the number of protons equals the number of electrons. The charge on an ion ... Proton Numbers Less Than or Equal to 82. Nuclei are composed of nucleons ... mass number has some odd-even fluctuation. Here are the incremental binding ... The number of neutrons in the nucleus is equal to A minus Z. chemical symbol. Two different forms, or isotopes, of carbon are shown below: Carbon-12: with 6 ... Feb 23, 2024 ... Because most elements (especially the smaller ones) tend to have one most common form of isotope and a low percentage of alternate isotopes, the ... Jul 30, 2023 ... Solution: Mass number = number of neutrons + number of protons. Number of protons is equal to the atomic number. We can find the atomic ... ... equal to Z + N (Figure 2). The mass of the nucleus in atomic mass units (amu) is usually slightly different from the mass number. Atoms of the same element ...
