From the given elements, Mg has the largest atomic radius, hence the size.
Of the elements listed by atomic symbol, Cs has the largest atoms.
For the representative elements (main group elements), atomic radius generally decreases from left to right across a period. Example: B and Fl: Fl has the smaller atomic radius Li and Be: Be has the smaller atomic radius
1 H Hydrogen3 Li Lithium11 Na Sodium
The atomic mass of Li, which stands for lithium, is approximately 6.94 atomic mass units (u).

Ca, Mg, Be, Fr, Cs, Rb, K, Na, Li, H
Rb is the largest, Li the smallest in the row above. Group 1 of the periodic table: Fr > Cs > Rb > K > Na > Li > H
Lithium has a larger atomic radius than hydrogen.
K (potassium) has the larger atomic radius.
Li+
lithium (Li)
Lithium is significantly larger.
As a general rule atomic radius decreases as you read across a period, so from largest to smallest the order would be Li, B, C, F.
No. Lithium and sodium are both from the same column of the periodic table and so have similar chemical properties. Lithium is atomic number 3 with a weight of 6.94. Sodium is much bigger and heavier with an atomic number of 11 and a weight of 22.99.
