A metal will tend to lose electrons and hence the atomic radius is higher than the ionic radius.
The alkali earth metal with the smallest atomic radius would be beryllium(Be), number four
Platinum is a metal element. Atomic mass of it is 195.08.
Sodium has a larger atomic radius and exhibits metallic properties due to its tendency to lose an electron and form positively charged ions. Phosphorus has a smaller atomic radius and tends to gain electrons to achieve a stable electron configuration, making it more likely to exhibit non-metallic properties.
The element with an atomic radius of 97 pm is Francium (Fr). Francium has a large atomic radius due to its location in the alkali metal group, which generally have larger atomic radii.
Barium is the largest alkaline earth metal atom in terms of atomic radius.

Samarium has a calculated atomic radius of 238 pm.
The alkali earth metal with the smallest atomic radius would be beryllium(Be), number four
The alkali metal with an atomic radius of 238 pm is potassium (K). Its large atomic radius is due to the added electron shells compared to other alkali metals in the same period.
Atoms increase in size as you go down a column and are larger going from right to left across a row.because while going from left to right in a period electrons enter in the same orbit and hence the attraction between the nucleus increasees
Because the metal loses an electron (making it smaller) and the non metal gains that electron, making it larger.
Polonium (Po) has an atomic radius of 168 picometers.
Gallium is a non metal element. Atomic mass of it is 70.
Platinum is a metal element. Atomic mass of it is 195.08.

Phosphorus has a smaller atomic radius and tends to gain electrons to achieve a stable electron configuration, making it more likely to exhibit non-metallic properties.
The element with an atomic radius of 97 pm is Francium (Fr). Francium has a large atomic radius due to its location in the alkali metal group, which generally have larger atomic radii.
Na has a larger atomic radius than Br. This is because Na is a metal and atoms in metals have larger atomic radii compared to nonmetals like Br, which has a smaller atomic radius due to its higher effective nuclear charge.
