What is the atomic number and atomic mass number of chlorine?
The atomic number of chlorine is 17.The atomic weight (after the IUPAC rules weight is the correct word in thiscase, for elements, not mass; mass is used only for isotopes) of chlorine is[35,446; 35,457], after the IUPAC tables, 2009 edition.
Is the atomic weight of chlorine 35.5 because of electrons?
No, electrons only make a negligible contribution to atomic weight. On the periodic table the atomic weight listed for most of the elements is the average of that element's isotopes. Chlorine has 2 common isotopes: Chlorine-35 (75.77% of all chlorine) and chlorine-37 (24.23%) This works out to an average mass of about 35.5.
What element has a 27 atomic mass?
The only element with a radioactively stable isotope with a mass number of 27 is aluminum.
Why is atomic mass of an element an average mass?
The Atomic Mass of an element is the numerical average of all the masses of the naturally occurring isotopes of that element proportionately. Man made elements do not count in supposedly. IE: If we have an element with atomic weight 100 and we have an isotope of that element with atomic weight 102 and if they occurred equally in nature then the Atomic Mass would be 101.
Do you need atomic number to find atomic mass?
no you do not need to know the atomic number, as that only equates to the number of protons in an atom. Most periodic charts will show you the atomic mass of an element

Which element have the atomic mass of 1?
The only such element is hydrogen.

What two elements have an atomic mass of 1?
only one element (hydrogen) has the atomic mass of 1.
What is the atomic mass for oxide?
It doesn't have an Atomic Mass, it is not an element (pure substance) it is a compound and therefore only has a molar mass.
What element has a 27 atomic mass?
The only element with a radioactively stable isotope with a mass number of 27 is aluminum.
What has an atomic radius of 099?
It is a difference between the empirical and the calculated atomic radius of an element; also all the values are only approximates. The empirical atomic radius of sulphur, phosphorous and chlorine is 100 pm. The calculated atomic radius of phosphorous is 98 pm.
What is the atomic mass for the element carbon is 12.011?
the atomic mass of just pure carbon would be twelve. the atomic mass is only effected by the number of protons and numbers of nuetrons
The chemical symbol formula for table salt is NaCL Which element has more atoms in the formula Which element has a larger share of the mass in the formula?
Na(sodium) has an atomic mass of 29.99, or about 30amu. Cl(chlorine) has an atomic mass of 35.453, or about 35amu. therefore, the one with more mass is chlorine. u kno this because the greater number is chlorine's. ^^ o and neither has more atoms in the formula than the other; ther r no subscripts in the formula, which means that ther is only 1 Na atom and 1 Cl atom. ^^ hope this helps! ^_^
Which element has an atomic mass of11?
Atomic mass numbers are not properties of elements overall, but only of particular isotopes of elements. The only stable element with an isotope with mass number 11 is boron. Beryllium and carbon also have isotopes with mass number 11, but these are radioactive.
How does Neutron emission from a nucleus affect an element?
It changes only the atomic mass.
Why is atomic mass of an element an average mass?
