Which alkali metal has the lowest atomic size?
The alkali metal with smallest atom is the Sodium. And,the atomic radius increases when we move down in a group in the modern periodic table. So,the topmost element (excluding hydrogen) in the group one will be the alkali metal with smallest atomic radius which is basically sodium.
Which atom has the smallest atomic weight?
Hydrogen
The lightest chemical element is Hydrogen and the heaviest is Hassium.
Which has the largest atomic size?
The carbon atom has the greater atomic size among all the other choices; they are nitrogen, fluorine, and oxygen.
Which non metal has the smallest atomic mass?
Name: Hydrogen.
Which radioactive element has the lowest atomic number?
Technetium
Technetium, with atomic number Z = 43, is the lowest-numbered element in the periodic table for which all isotopes are radioactive.
Which metal has largest atomic size?
Francium
Francium has the largest atomic size on the periodic table, and helium has the smallest atomic size.
Which has the largest atomic size in Aluminium?
Aluminum Element has Largest Atomic radius. Given Elements : Aluminum, Silicon, Phophorous and Sulphur belongs to Third period. In a period , as we go from left to right in a periodic table, atomic number increases .
What metals can float?
Lithium, sodium, and potassium have low densities and float on water. Rubidium and Caesium are denser and sink in water. Lithium has a density of 0.53 g/cc it will float on water and any other metal with a density even slightly greater than 1 g/cc will sink.
Which metal has the largest atomic mass?

What is the smallest element that can be considered a metal?
The smallest atomic sized element that is definately a metal is Beryllium. The reason for this is that Beryllium has more protons and thus pulls the electrons more tightly around itself, thus making the electron s-orbital smaller.
Which element has the smallest atomic size in the period?
Alkali metals has smallest atomic size in the period. > Alkali metals has smallest Alkali metals has smallest atomic size in the period. First ionization energy of nitrogen is lower than oxygen. In a period, noble gases have largest atomic size and alkali metals have second largest atomic size.
Which element has the least number of protons in the atom?
Many people will think it is Lithium as it is the metal with the least number of protons… but they would be wrong. The smallest atomic sized element that is definately a metal is Beryllium.
What is the lightest or least dense metal?
The lightest or least dense metal that is a pure element is lithium, which has a density of 0.534 g/cm3.This makes lithium nearly half as dense as water, so if lithium was not so reactive, a chunk of the metal would float on water. The answer below that says hydrogen does not address the question properly.
