hydrogen
Hydrogen has the smallest atomic radius - 25 pm.
Potassium. This can be seen by the potassium setting itself on fire in water. Can lithium, carbon or hydrogen do that?
No - the lightest elements are hydrogen and helium. Although lithium is a lightest metal and the lightest element that is a solid at room temperature.
The lightest element would be helium
No. Lithium will lose an electron.
Lithium is the smallest element in the periodic table if Hydrogen and Helium are excluded.
Hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium have one valence electron.
The smallest element known to man is Hydrogen (H).
Guessing its H+
Hydrogen has the smallest atomic radius - 25 pm.
Lithium
Lithium.
Hydrogen is the lightest element. The isotope protium is the lightest kind of hydrogen atom.
hydrogen and lithium
T he smallest first ionization energyis for lithium.
If you look at the periodic table, Lithium (Li) is in the first column, group 1A, under Hydrogen, and above Sodium (Na). These elements are typically "electron donors" to fill out their electron shell. So, Lithium, Hydrogen, and Sodium all would typically ionize with +1 charges.
