1.45 rounded to the nearest whole number is 1.0.
1 rounded to the nearets ten would be 0.

The atom that has the lowest mass is hydrogen. So assuming the same numbers of atoms in each element, hydrogen would be the element with the lowest mass.

Hydrogen has one proton in its nucleus.
The atomic number of hydrogen is 1
there are many isotopes of hydrogen. they are:-hydrogen -1 protium. hydrogeen - 2 deuterium.hydrogen - 3 tritium. hydrogen - 4 hydrogen - 5 hydrogen - 6 hydrogen - 7
