No, because a mass is the amount of matter and object has, while the weight is caused by gravity pushing down onto the object.
The weight of an object is usually about 10 times the mass.
The term atomic weight is used for chemical elements (after the rules of IUPAC).
The term isotopic mass is used only for a specific isotope.
an oxygen and a hydrogen atom do not weight the same
The formula mass of neon is equal to its atomic mass in atomic mass units (amu). This is because neon, like all elements, exists as individual atoms and its formula weight is the same as its atomic weight.
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.
If an atom looses an electron, neither the atomic mass nor atomic weight change appreciatively. If it looses a proton or neutron, both atomic mass and atomic weight decrease by one and it becomes an atom of a different element (on loss of a proton), or a different isotope of the same element (upon loss of a neutron).
The atomic weight of bromine is 79,904 amu.
isotopes always have the same? mass # & atomic #, or atomic # and atomic weight, or atomic # but different mass #'s
No, the atomic number is the amount of protons it has and the weight is its mass
the best talaga
Atomic mass - Atomic weight are the same , so look at your periodic table and below every element it will give you atomic mass.
No. The atomic weight is the number on the Periodic Table and is a weighted average of the atomic masses.
Mass number: sum of protons and electrons in the nucleus of an isotope. Atomic weight: mass of a chemical element expressed in unified atomic mass units.
Unified atomic mass unit
The atomic weight is taken as the average weight or mass of the different isotopes of the Same atom That exists in the different %age in our enviromenT
It means that atomic weight is expressed in form of Molar weight. When we write that the atomic mass of an element is X, it means that it is X amu(atomic mass unit) and not X grams. An atomic mass unit is very less as compared to a gram. The molar mass of an element or compound is its same mass as in amu but in grams.
The expression atomic mass is used only for isotopes; the atomic mass is the mass of an atom expressed in unified atomic mass units - (1 amu = 1/12 atomic mass of carbon-12).For elements the expression is atomic weight; the unit is the same.
an oxygen and a hydrogen atom do not weight the same
Isotopes - that same element with a different atomic weight.
