(D) The mass of $1$ atom is given as $10.86 	imes 10^{-26} \ kg = 10.86 	imes 10^{-23} \ g$.To find the molar mass (atomic weight),we multiply the mass of one atom by Avogadro's number $(N_A = 6.023 	imes 10^{23} \ mol^{-1})$.Molar mass $= (10.86 	imes 10^{-23} \ g) 	imes (6.023 	imes 10^{23} \ mol^{-1}) \approx 65.40 \ g/mol$.The element with an atomic weight of approximately $65.40 \ g/mol$ is Zinc $(Zn)$.

The element whose $1$ atom has a mass of $10.86 \times 10^{-26} \ kg$ is
