What is indicated by the atomic mass?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
How does atomic mass indicated element reactivity?
There is no good correlation lies between the element reactivity and the atomic mass.
What is the top number in an isotope?
An isotope is identified by atomic number (element number or name), by mass number, and by atomic weight. The mass numberfor an isotope is listed as a leading superscript such as 29Si, which in this example is silicon containing 14 protons and 15 neutrons (a rarer but stable isotope of the element). Similarly the atomic weight is indicated by a superscript such as U235 , an isotope of uranium having 92 protons and 143 neutrons.The actual atomic weight is often expressed as a decimal number corresponding to the mass of the atom in "atomic units", where a proton is about 1.0072, a neutron 1.0086, and an electron about .00055 atomic units.
What is an example of Atomic Number?
Atomic number= number of protons. Hydrogen atomic number=1
What is the atomic number of F plus the atomic number of Na?
The atomic number of fluorine is 9.The atomic number of sodium is 11.
The number of protons an atom contains is indicated by its?
Atomic number.
The number of atoms of each element present in the molecule is indicated by what?
A subscript number after each atomic symbol in a formula for the compound.
How do you determine how many protons are in an element?
Experimentally, I'm not sure, but I know you can look at your periodic chart, the large number over the symbol of each element is teh number of protons in that element.
What is indicated by the atomic mass?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
How many valence electrons does a neutral magnesium atom have?
12, the same as the number of protons indicated by magnesium having an atomic number of 12.
What is the number of protons in the neucleus called?
the answer is that it is called a atomic number.
How does atomic mass indicated element reactivity?
There is no good correlation lies between the element reactivity and the atomic mass.
Atomic number in the atomic nucleus?
The atomic number is equal to the number of the protons in the atomic nucleus.
The number of neutrons in an atom can be found by subtracting the atomic number from the?
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.
This element has an atomic number that is double the atomic number of silicon?
this elemnt has an atomic number that is double the atomic number of silicon?

What is the number of neutrons in an atomic number?
Subtract the atomic number from the atomic weight.
