The atomic mass is equal to: A. the number of neutrons. B. the number of protons plus the number of electrons. C. the number of protons plus the number of neutrons. D. the number of electrons. E. the number of protons. The number of protons and neutrons is known as the ___...
Step 1:Find the number of protons in an atomic ion. The number of protons is equal to the atomic number of the element. The atomic number of potassium (K) is 19. Therefore, the number of protons is 19. Step 2:Find the number of electrons in an atomic ion ...
(General Physics) a stable, positively charged elementary particle, found in atomic nuclei in numbers equal to the atomic number of the element. It is a baryon with a charge of 1.602176462 × 10–19coulomb, a rest mass of 1.672 62159 × 10–27kilogram, and spin ...
#化学小知识# The number of protons in the nucleus of an atom is referred to as the atomic number, or proton number, Z. 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 ...

The number of protons in the nucleus of an atom is referred to as the atomic number, or proton number, Z. 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...
Atomic number of an element is equal to the number of protons it bears inside the nucleus. And on the other hand, the atomic mass of an element is equal to the total mass of protons and neutrons inside the nucleus. Thus both atomic number and atomic mass depend on the number of protons...
equal to the atomic number unless Are also equal to the atomic number unless the atom is an ion such as a the atom is an ion such as a ––1, 1, - -2, 2, --3… 3… Example Example Helium has an atomic # of 2 and a atomic Helium has an atomic # of 2 and a atomic ...
Atomic Number The atomic number represents the number of protons in an atom's nucleus. In an uncharged atom, the number of protons is always equal to the number of electrons. For example, carbon atoms include six protons and six electrons, so carbon's atomic number is 6. ...
Like finding the number of protons, finding the number of electrons in a neutral isotope requires finding the atomic number of the element. Advertisement In an ion, an isotope with a positive or negative charge, the number of protons doesn't equal the number of electrons. If protons out...
