Atomic number is the number of a chemical element in the Periodic Table of Mendeleev; it is equal in the neutral state with the number of protons or electrons.
Atomic weight is the mass of a chemical element (considering the isotopic composition) expressed in Atomic Mass units.
What else can I help you with?
What is the difference between atomic number and atomic mass weight?
Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
What is the difference between the atomic number mass number and atomic mass?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the difference between the atomic number and average atomic mass?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is difference between atomic weight and atomic mass?
Atomic Mass is the mass of an atom in Atomic Mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
What is the difference between atomic mass and atomic weight?
Atomic Mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
Which particles account for the difference between the atomic number and the mass number?
The answer is that it is neutrons that account for the difference between atomic weight and atomic number. The atomic number is the number of protons or the number of electrons in the atom, since they are normally equal. The atomic weightis the sum of the total number of protons, electrons AND neutrons in the atom. Knowing both the atomic number and the atomic weight of an atom lets you know the number of neutrons in the atom (the isotope). Example: Uranium, Atomic Number 92, Atomic Weight 235. The atomic number tell you that the uranium atom has 92 protons and 92 electrons. The atomic weight tells you that it has a combined total of 235 protons, electrons and neutrons. Since you know from the atomic number that there is a total of 184 protons and electrons in the atom (92 + 92) and from the atomic weight that the total number of protons, electons and neutrons is 235 (92 + 92 + X = 235), you now know that there are 151 neutrons in that uranium atom. The atomic number and atomic weight together tell you that the uranium atom 235 has 92 protons, 92 electons and 151 neutrons.
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.
Is the atomic weight the same as the atomic number?
No, the atomic number is the number of protons that an atom contains. Atomic weight is the number of protons and neutrons.
How was is the atomic number and the atomic weight of uranium found?
Atomic number of uranium: 92 Atomic weight of uranium: 238,02891
Atomic weight and atomic number of copper?
Its atomic number is 29 and its standard atomic weight is 63.5 g/mol.
What is the number of neutrons in an atomic number?
Subtract the atomic number from the atomic weight.
What is the number in front a chemical formula is called?
atomic number or atomic weight. Subscript: atomic number, superscript: atomic weight: 94Pu239 or 239Pu
