In an element’s square on the periodic table, the number with the greatest value represents the
1 answer:
Answer: D.atomic mass.
Explanation: The general representation of an element is given by:
X = chemical symbol of element
Z= atomic number= which represents the number of electrons.
A= mass number or atomic mass =which represents the number of electrons + number of neutrons
Thus mass number is greater than number of electrons and number of neutrons as it is the sum of both.

The deuteriuoted water that is consists of an isotope of hydrogen in place of hydrogen from the normal water. The approximate mass of deuteriuoted water and normal water can be calculated as {(2×2)+16} = 20. However the exact mass of
is 20.027 g/mole, whereas the mass of water can also be calculated as- {(1×2)+16}=18, however the exact mass of (
) molecule is 18.015 g/mole. Thus the difference between the mass of the molecules are (20.027 - 18.015) = 2.01 2g/mole.
