Differences between Mendeleev 's and Moseley 's periodic law?
Mendeeleve’s periodic table “ The properties of the elements are a periodic functon of their atomic weights”. Following are the properties
Mosely Law: Henry Moseley discovered that the wavelength (energy) of an X-ray depended upon the nuclear charge of an atom. Moseley's Law describes the relationship between atomic number and wavelength of a spectral line:
The constant σ (sigma) is equal to 1 for the K-lines and 7.4 for the more shielded L-lines. For energy this expression is approximately equivalent to:
Moseley's determination of this relationship provided a simple test of the order of the elements according to Z. Where Z denote atomic number of an element.

I agree with both of your friends...........
mendeleev 's periodic law ws based on atomic masses
n as it stated
' 'the properties of elements are the periodic function of their atomic masses ' '
moseley 's periodic law ws based on atomic numbers
n as it stated
' ' the properties of elemnets r the periodic function of their atomic numbers ' '
hope i helped... :))
in mendelleevs periodic table ,the mendeleevs periodic law states that properties of elements r periodic functions of their at mass
modern law states that prpperties of elements r periodic fun of at nos
if u want more give a thumb up there r 6 more difference 2 come......
