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.

Atomic mass is 35.453?
Chlorine is a non metal element. Chlorine atomic mass is 35.453.
What is chlorine's atomic weight?
It has an atomic mass of 35.4527
Why chlorine has atomic weight 35.5 though no chlorine with mass exist in nature?
The atomic weight (not mass) of chlorine is now [35,446; 35,457]. I don't understand "no chlorine with mass exist in nature".
Why atomic weight of chlorine is 35.5 though isotopes of chlorine 35 and 37?
The atomic weight for each element on the periodic table represents a weighted average of the masses of all naturally occurring isotopes of an element. Because of this, the elements do not have whole-number atomic weights. An exception is the atomic weight for some elements written inside parentheses. These elements do not have stable isotopes and the atomic weight listed is the atomic weight for the longest lived isotope.
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.
What is the name of the element with an atomic weight of 35.453?
Chlorine (Cl), atomic number 17.
Which element has no atomic weight?
all elements have an atomic weight, because all of them have electrons and protons, and every electron and proton have a weight.
Atomic mass is 35.453?
Chlorine is a non metal element. Chlorine atomic mass is 35.453.
What is Equivalent weight of chlorine?
the equivalent weight of chlorine is 35.453, which is also it's atomic weight.
Which is greater the mass of a carbon atom or a chlorine atom?
Florine has a greater Atomic Weight because Carbon has a Atomic Weight of 12 amu (atomic mass units) while Florine has a Atomic Weight of 19.
What is chlorine's atomic weight?

According to the Periodic Table of Elements Chlorine has 35.45 protons?
No. chlorine has an atomic weight 0f 35.45. and has an atomic number (number of pprotons) of 17. It has two naturally occuring isotopes chlorine-35 and chlorine -37. It is the presence of these that causes the fractional atomic weight
Atomic weight of chlorine?
35.453 ------------- The relative atomic weight (not mass) of chlorine is after IUPAC tables from 2009 [35,446; 35,457]; the conventional value is 35,45.
Does carbon have a greater molar mass then chlorine?
Atomic weight of carbon: [12,0096; 12,0116]. Atomic weight of chlorine: [35,446; 35,457]. The molar mass of chlorine is greater; rounded 35,45 g/mol.
What is the atomic number and atomic mass number of chlorine?
