State why the atomic weight of an element is also termed - relative atomic mass.

Atomic mass of an element is

If the atomic weight of an element is 23 times that of the lightest element and it has 11 protons, then it contains.

Assertion (A) : The isotopes are the atoms of the same element with different atomic masses. They require different positions in the periodic table. Reason (R) : Variable number of neutrons in the nuclei of the atoms of same elements leads to the different atomic masses.

The weight of 1 atom of an element is 8 x 10^-23 .what is its atom mass?

The weight of 1 atom of an element is 7 x 10^-23 .what is its atom mass?

The atomic number of an element is more important to the chemist than its relative atomic mass. Why ?

Find the number of g atoms and weight of an element having 2 xx 10^(23) atoms. Atomic mass of element is 32.

Find the number of g atoms and weight of an element having 2 xx 10^(23) atoms. Atomic mass of element is 32.

According to the periodic law of elements, the variation in properties of elements is related to their : atomic masses nuclear masses atomic numbers nuclear neutron-proton number ratios.

Approximate atomic weight of an element is 26.89 . If its equivalent weight is 8.9 , the exact atomic weight of element would be
