Hydrogen has the smallest atomic radius - 25 pm.
Among hydrogen, lithium, and sodium, hydrogen has the smallest atomic radius because it has the fewest number of electron shells and the smallest number of electrons, leading to a smaller atomic size.
Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius
The smallest atom is lithium, as it has a smaller atomic radius compared to fluorine. This is because as you move across a period on the periodic table, atomic radius decreases due to increased nuclear charge pulling the electrons closer to the nucleus.
No, the atomic radius of neon (Ne) is smaller than that of lithium (Li). This is because as you move across a period in the periodic table, the atomic radius decreases due to increasing nuclear charge and stronger attraction for electrons.
Generally, any element with a lower atomic number.
Among hydrogen, lithium, and sodium, hydrogen has the smallest atomic radius because it has the fewest number of electron shells and the smallest number of electrons, leading to a smaller atomic size.
Lithium has the smallest atomic radius among the elements listed.
It is hydrogen.
The element in group 1 with the smallest atomic radius is lithium, due to its higher nuclear charge compared to the other elements in the group (such as sodium and potassium). This higher nuclear charge attracts the electrons more strongly, leading to a smaller atomic radius.
The answer choices for this question wasn't provided. Oxygen has the smallest atomic radius. The higher the electronegativity in an element makes the atomic radius smaller.
Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius
Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius The protium isotope of hydrogen has the smallest nucleus radius. It is 1.6 fm
Lithium(520)
Fluorine has the smallest anion radius among the elements.
The atomic radius of lithium is approximately 1.23 angstroms.
The smallest atom is lithium, as it has a smaller atomic radius compared to fluorine. This is because as you move across a period on the periodic table, atomic radius decreases due to increased nuclear charge pulling the electrons closer to the nucleus.
Atomic Radius gets greater down the periodic table and gets smaller to the right in the periodic table. This means, in order of atomic radius, that the five smallest elements are Helium, Neon, Fluorine, Oxygen, and Hydrogen in that order.
