Postassium, K, has a larger radius than sodium, Na, because it is in the next period on the table but in the same group as sodium.
Na has a higher atomic radius then Na+, since it still has it's outer electron (3s).
The neutral atom of potassium has the largest radius.
Look at your periodic table and you will see that K, potassium, must have the largest radius of these choices. You know that, K + and Na + will be small in radius because they have donated an electron to become positively charged cations.
Na+ is smaller than Na.
Potassium has the largest atomic radius.
Sodium has a larger atomic radius than aluminum.
K
Postassium, K, has a larger radius than sodium, Na, because it is in the next period on the table but in the same group as sodium.
Na has a higher atomic radius then Na+, since it still has it's outer electron (3s).
The neutral atom of potassium has the largest radius.
a) Sc,Ti,V,Crb) Na,K,Rb,Csc) B,Si,As,Ted) F,Cl,Br,Ie) Na,Mg,Al,SiThe correct answer of these options is a) Sc,Ti,V,Cr because they are the closest elements to each other in the periodic table.
Rb is the largest, Li the smallest in the row above. Group 1 of the periodic table: Fr > Cs > Rb > K > Na > Li > H
By the trend it is Na...(Bigger the farther left and bigger towords the bottom)
Examples: Cl-, Na+, Br-, K+, Li+, U4+ etc.
na
Look at your periodic table and you will see that K, potassium, must have the largest radius of these choices. You know that, K + and Na + will be small in radius because they have donated an electron to become positively charged cations.
