What alkali metal has an atomic radius of 238 pm?
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.
Which elements has the largest atomic radii in periodic table?
The atomic radii of members of the Group 1A (Alkali metals), increases down the group. Therefore Francium has the largest atomic radius of the Alkali metals. However Fr has no stable isotopes, thus is not naturally occurring. So Cs-133 is the largest you can find.
What is the largest element in the alkali metal?
No. In fact lithium, one of the alkali metals, is the lightest metal. In terms of molecular mass the heaviest metals are the actinides. In terms of density the densest metals are osmium and iridium.
Why do alkali's get softer down the group 1?
Alkali metals get softer down Group 1 due to an increase in atomic size and weaker metallic bonding. As you move down the group, the atomic radius increases, leading to a decrease in the strength of metallic bonding and making the metals softer.
Why melting point decrease down the group for Alkali metals but increase for Halogens?
The melting point decreases down the group for alkali metals because the metallic bonding weakens as the atomic size increases, resulting in weaker intermolecular forces. For halogens, the melting point increases down the group due to stronger van der Waals forces between larger molecules with increased electron cloud size, resulting in higher melting points.
Which alkali earth metal has the smallest atomic radius?
The alkali earth metal with the smallest atomic radius would be beryllium(Be), number four

What is the larger element in the alkali metal family?
Francium has the most larger atomic weight and also the largest atomic radius between the alkali metals.
What is the biggest element in the alkali family?
Francium has the biggest atomic weight and the biggest atomic radius between the alkali metals.
How do sizes of atoms of alkali metals compared to their positive ions?
The atomic radius of cations is lower.
Why is there a pattern between the atomic radius and melting points within alkaline earth metals or period 2 metals?
The pattern between atomic radius and melting points in alkaline earth metals or period 2 metals is due to the relationship between the attractive forces within the atoms (which decrease with larger atomic radius) and the intermolecular forces that hold the atoms together in the solid state. As atomic radius increases, the intermolecular forces become weaker, making it easier for the metal to melt at a lower temperature.
What is the largest element in the alkali metal?
No. In fact lithium, one of the alkali metals, is the lightest metal. In terms of molecular mass the heaviest metals are the actinides. In terms of density the densest metals are osmium and iridium.
Were on the periodic table would you find atoms with the largest atomic radius?
Atoms with the largest atomic radius will be found in the lower left corner of the periodic table, specifically in the alkali metals and the alkaline earth metals groups. This is because these elements have the fewest protons in their nucleus relative to their electron cloud, resulting in a larger atomic size.
Why do alkali's get softer down the group 1?
Alkali metals get softer down Group 1 due to an increase in atomic size and weaker metallic bonding. As you move down the group, the atomic radius increases, leading to a decrease in the strength of metallic bonding and making the metals softer.
What group of elements have members of the smallest atomic radii for a given period?
The group of elements with members of the smallest atomic radii for a given period is the group of noble gases. Noble gases have the smallest atomic radii because they have a completely filled valence shell, which results in strong electron-electron repulsions and a smaller atomic size.
Are ions of alkali metals larger or smallest than ions of alkaline earth metals from the same period?
Ions of alkali metals are generally larger than ions of alkaline earth metals from the same period because alkali metals have only one outer electron, leading to a larger atomic radius and therefore a larger ion size compared to alkaline earth metals, which have two outer electrons.
