If we talk about an electric wire with the same length and weight, then metal sodium has the lowest resistivity. Its conductivity is much better than silver, copper or aluminum, but it strongly reacts with oxygen or water. Also lithium and calcium are better conductors than silver (at the same wire length and weight), but are very reactive as well.
Heat generated by electrical resistance. Thermal mass of a metal plate.
The metal in group 14 with the lowest atomic mass is tin (Sn), which has an atomic mass of approximately 118.71 atomic mass units.
In a given period, the element with lowest atomic mass will belong to group 1. It should also be noted that lithium is the metal with the smallest atomic mass.
Among the groups mentioned, lithium (Li) is the alkali metal with the lowest atomic mass, at approximately 6.94 u. In the alkaline earth metals, beryllium (Be) has the lowest atomic mass at about 9.01 u. For halogens, fluorine (F) is the lightest, with an atomic mass of around 19.00 u, and in the noble gases, helium (He) has the lowest atomic mass, approximately 4.00 u. Thus, helium has the lowest atomic mass overall among these groups.
Mass
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.
Bromine, because Bromine has an atomic mass of only 5.
Titanium (Ti) has an atomic mass of approximately 47.9. It is a transition metal known for its strength and corrosion resistance, commonly used in aerospace and industrial applications.

Hydrogen gas has the lowest mass per mole, with a molar mass of approximately 2 grams per mole.
Mass measures the body's resistance to acceleration.
brass, it has the lowest density and hence the least mass, therefore more force goes into acceleration.
