If the atomic weight of `Zn` in `70` and its atomic number in `30`, Then what be the atomic weight of `Zn^(2+)`?

What is the atomic weight of Lithium?

What is atomic weight ?

If W is atomic weight and N is the atomic number of an element, then

Atomic weight of Th is 232 and its atomic number is 90. The number of alpha - and beta -particles which be lost so that an isotope of lead (atomic weight 208 and atomic number 82) is produced is

Medeleeff corrected the atomic weight of :

The atomic radius of Zn is __ than that of Cu.

The atomic weight of an element is 52 and its atomic number is 24. The number of electrons, protons and neutrons in an atom of this element will be respectively
