Atomic Mass is the mass of an atom
Atomic weight is the average mass of an atom based on the abundance of different isotopes
No, because mass and weight are two different things. Weight is gravitational pull, while mass is how much matter there is in an object.

∙ 15y agoNo. Isotopes of an element, is the atom of that element with different number of neutrons. Neutrons have a mass of approximately one AMU and therefore the mass of an atom will change with the varying amount of neutrons. And when mass changes, weight changes.
Wiki User
∙ 13y agoNo. All atoms of an isotope of the element weigh the same, but a sample of an element is typically made of several different isotopes, to give a weighted average weight. This is the value shown on the Periodic Table.
No. All isotopes do not weigh the same because of the differed number of neutrons. However, same isotopes weigh the same even if it loses or gains electrons.
Wiki User
∙ 10y agoNo. The weight of an atom varies greatly among elements, and is the main reason why some objects possess greater weight for a given volume (density).
The weight of an atom is practically all in the nucleus, consisting of protons and neutrons, and a neutron is very slightly heavier than a proton. An electron is 1/1800th the weight of a neutron, so electrons are only a fractional contribution to an atom's weight.
Regarding comparative weight, one atom of uranium-238 weighs more than 238 atoms of hydrogen.
Wiki User
∙ 14y agoNo. By definition, an isotope is a form of an atom that differs in the number of neutrons. Neutrons are matter and, therefore, have mass. If a given isotope has a higher number of neutrons than another isotope of the same atom, it will obviously weigh more.
Wiki User
∙ 13y agoMost of the time atomic mass and atomic weight are considered to be the same thing. Although this is still debated by scientist, you will find this on the periodic table and it is the sum of the mass of protons, neutrons, and electrons in an atom.
Wiki User
∙ 13y agoThe mass number is NOT the atomic mass. The mass number is the number of protons + neutrons in a given isotope - so it is always a whole number. The atomic mass is the measured mass of a given isotope and includes electrons - the units given are called universal atomic mass units (abbreviated u or amu). Atomic mass is not a whole number and is calculated to several decimal places.
Wiki User
∙ 12y agoNo. The mass is the amount of matter an object contains, while the weight is caused by gravity pushing down on the object. The weight is usually about 10 times the mass.
Wiki User
∙ 14y agoYes. Isotopes of a given element are of identical mass. Of course, different Isotopes of that element will vary in their mass, as it depends on its number of Neutrons.
Wiki User
∙ 13y agoNo; some of the atoms may have more or fewer neutrons.
Atoms of the same element with a different atomic weight are called isotopes.

Can 2 isotopes of the same element differ in the number of protons?
An element is defined by the number of protons, so this cannot vary. Isotopes of a particular element are different in the number of neutrons within the atoms. These isotopes are said to be comparatively "lighter" or "heavier" than other isotopes based on the total of protons and neutrons (atomic mass).
Is mixtures or isotopes are atoms of the same element with different numbers of neutrons?
Atoms have isotopes: it is true, the isotopes of the same element have different number of neutrons.
True or false atoms of different elements have the same never of protons?
All atoms of the same element are the same.7) Isotopes are a family of atoms all of which have the same number of electrons, have the same number of protons in their atomic centers, but different numbers of neutrons.
Did the existence of isotopes affect the validity of the atomic theory?
Dalton's theory said that "atoms of the same element are the same as each other in terms of mass, color, and size." We know that this cannot be true because isotopes of the same element, oxygen for example O-16 and O-17, have different mass numbers (atomic mass).

How many neutrons are there in the nucleus of an atom of lithium if the atomic number is 7?
The amount of neutrons can change among elements atoms of the same type element. These are called isotopes. Lithium actually has an atomic number of 3. An atomic number means how many protons it has. The problem most likely means that it has an atomic mass of 7. If that is true, it becomes easy. Atomic mass means the total weight of the element. A proton and a neutron each weigh '1.' All you have to do is look and see that lithium has an atomic number of '3' which means that it has 3 protons. You subtract that from the mass to get an answer of 4. This means that lithium in this example has 4 neutrons.Electrons aren't counted in the mass of the element because they weigh so little. That is the same reason why a neutron (which is technically a proton and an electron together) has the same weight as a regular proton.
Is it true that The atomic weight is only an average of relative weights of an atom and its isotopes and it may vary from the weight of a specific isotope?
True
The number of neutrons is equal to the atomic number true or false?
False as a generalization but true for some isotopes. The atomic number is the number of protons in a nucleus, which may coincidentally be the same as the number of neutrons but is not required to be.
Base weight a system of comparing atomic weights to carbon is it true or false?
True. The unit for the atomic weights of chemical elements is the relative atomic mass unit (1/12 from the atomic mass of the isotope 12C). Note that atomic weights is used for elements and atomic mass for isotopes.

Is it true Different isotopes for the same element will always have the same numbers of neutrons?
Yes. it is true. Isotopes of the same element always have different number of neutrons.
Is mixtures or isotopes are atoms of the same element with different numbers of neutrons?
Atoms have isotopes: it is true, the isotopes of the same element have different number of neutrons.
The atomic number of isotopes is determined by the number of atoms. true or false?
False. Number of neutrons.
Is an element made up of atoms with the same number of protons?
Isotopes of an element have the same number of protons and electrons, but different numbers of neutrons. Any element is made up of a combination of isotopes. For example if you are looking at carbon, there is carbon-12 and carbon-13, which are stable, and carbon-14 which is radioactive. This is true for many elements, and the atomic mass, the one displayed on the periodic table, is an average of the masses of all of the isotopes. But the atomic number of all isotopes is the same. http://www.chem4kids.com/files/atom_isotopes.html http://www.colorado.edu/physics/2000/isotopes/index.html

Does the Bohr model look the same for zinc and its isotopes?
Yes, it is true.
WHAT Equals the sum of the number of neutrons and protons in an isotope?
The atomic mass equals neutrons and protons. This is true in non isotopes as well.
