The sum of the number of protons and the number of nuetrons.
The number of protons, electrons, and neutrons:P
The atomic mass of an element is equal to the number of protons.
the total number of protons and neutrons in the nucleus.
The mass number of an element is equal to the sum of protons and neutrons in the nucleus, while the atomic number corresponds to the number of protons. These values can be found on the periodic table for each element.
The mass number of an element is equal to the number of protons in the nucleus, and this always determines the element in the Periodic Table. Different isotopes of the same element have differing numbers of neutrons in the nucleus, but always the same number of protons.
The Atomic Mass is equal to the number of protons and electrons that an element has.
The number of protons, electrons, and neutrons:P
The atomic mass of an element is equal to the number of protons.
The element's average atomic mass.
the total number of protons and neutrons in the nucleus.
The atomic mass number does not equal the number of electrons in the element. The atomic number, on the other hand, does usually equal the number of electrons in the element, With the exception of ions.
No, the mass number of an element is the sum of protons and neutrons in the nucleus. To determine the number of electrons, you would need to know the atomic number of the element, which is equal to the number of protons. Electrons in a neutral atom equal the number of protons.
The mass number of an element is equal to the sum of protons and neutrons in the nucleus, while the atomic number corresponds to the number of protons. These values can be found on the periodic table for each element.
1. The molecular mass of a compound is the sum oh the atomic weights of the elements contained in the molecule of this compound. 2. The atomic number of an element is the number of this element in the Periodic Table of Mendeleev; the atomic number is equal to number of protons and electrons.
This is the cabon isotope 612C.
The mass number of an isotope of an element is equal to its atomic mass number. However, the atomic weight of an element is a weighted average of the isotopes that occur in the element in nature. Because almost all elements have more than one naturally occurring isotope (if they have any), the atomic weights of most elements are not integers, as mass numbers always are.
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.
