Moseley made revisions to the periodic table that resolved some of the problems with mendeleev’s version. which of these was a result of his revisions to the periodic table?

The revised periodic table could account for variations resulting from isotopes.

Explanation:

Dmitri Mendeleev was the first person to form the periodic table.

There are certain draw backs in Mendeleev's periodic table which need to be amended.

One such problem is that Mendeleev's periodic table lacks separate place for isotopes of an element.  The isotopes share the same place in his periodic table. Hence, if a revised periodic table was formed in which there are separate places for the isotopes of an element then this problem can be amended.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
