The atomic weight of an atom depends on the number of protons and neutrons in one atom of the element, and is usually the average mass of all the known natural isotopes of the element. The atomic weight refers to the force of gravity on one atom of the element.
After the IUPAC rules the Atomic Mass is a term used only for the mass of isotopes; and the atomic weight is the term used for an element.
The atomic weight of an atom is determined by the mass of its constituent particles, the protons, electrons, and neutrons. In practice, however, the electrons are so much smaller than the protons and neutrons, and the neutrons are close enough to the mass of the protons, that it is common to say that the atomic weight is the number of protons plus the number of neutrons. This is not exact, however, and the Periodic Table reflects this.
What else can I help you with?
Which of the following determines the identity of an element atomic number mass number atomic mass or overall change?
Atomic number determines the identity of an element. It represents the number of protons in an atom's nucleus, which is unique to each element. Mass number refers to the total number of protons and neutrons in an atom's nucleus, while atomic mass is the average mass of an element's isotopes. Overall charge is determined by the number of protons and electrons in an atom, but it does not uniquely identify the element.
What is the number of protons in one atom of an element determines the atom?
The number of protons determines the element's atomic number. When combined with the number of neutrons, it determines the element's atomic mass.
Which particle determines the atomic number of an element?
The atomic number of an element is determined by the number of protons.
Is there an element that has the same atomic number and atomic mass?
No, there is no naturally occurring element with the same atomic number and atomic mass. The atomic mass of an element is the weighted average of the masses of its isotopes, which have different numbers of neutrons. The atomic number of an element is the number of protons in its nucleus, which determines its identity. Therefore, the atomic number and atomic mass are different for each element.
How are the atomic mass and the atomic number different?
The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of the number of protons and neutrons in the nucleus. Atomic number determines an element's identity, while atomic mass affects its atomic weight and isotopes.

Atomic number determines the identity of an element. It represents the number of protons in an atom's nucleus, which is unique to each element. Mass number refers to the total number of protons and neutrons in an atom's nucleus, while atomic mass is the average mass of an element's isotopes. Overall charge is determined by the number of protons and electrons in an atom, but it does not uniquely identify the element.
What determines the atomicity of the elements?
The Atomic Mass number tells the atomic mass of an element. The mass is calculated as the mass of all the protons and neutrons in the center of an atom.
What is the number of protons in one atom of an element determines the atom?
The number of protons determines the element's atomic number. When combined with the number of neutrons, it determines the element's atomic mass.

What is a mass number atomic mass number?
The atomic number is the number of protons in an atom. This number is fixed and determines what element that atom is. The Atomic Mass is the mass of an atom and is roughly equivalent to the number of protons plus the average number of neutrons that atoms of that particular element.
What is the difference between the atomic number and atomic mass?
The atomic number represents the number of protons in an atom's nucleus. It determines the element's identity. Atomic mass is the average mass of an atom of an element, taking into account its isotopes and their abundance. It is the sum of the protons and neutrons in the nucleus.
What is an atomic number and a mass number?
The atomic number is the number of protons in an atom. This number is fixed and determines what element that atom is. The atomic mass is the mass of an atom and is roughly equivalent to the number of protons plus the average number of neutrons that atoms of that particular element.
What is the difference between atomic number and atomic mass?
Atomic number refers to the number of protons in an atom's nucleus, which determines the element's identity. Atomic mass is the average mass of an atom of that element, taking into account the mass of protons, neutrons, and electrons. Atomic mass is measured in atomic mass units (amu).
The difference between the atomic number of an element and its atomic mass?
The atomic number of an element represents the number of protons in its nucleus, which determines its position on the periodic table and its chemical properties. The atomic mass (or atomic weight) of an element reflects the average mass of its isotopes, considering both protons and neutrons. In general, the atomic number is a whole number without units, while atomic mass is usually expressed in atomic mass units (amu).
What is the difference between the atomic number and the atomic weight of the known elements as listed on the periodic table?
The atomic number of the element is the number of protons or number of electrons in an atom of the element . The atomic weight of the element is the ratio of the mass of the atom to the 1/12th of the mass of the atom of carbon 12.
