Answer: According to the reactivity of metals Sodium is the second metal while Magneesium is the fourth metal. The metal in the top of the reactivity serise table are more reactive.
<em>(The series obtained by the arrangement of metals in the decending oder of their reactivity is the REACTIVITY SERIES TABLE)</em>
Explanation:
K
<u><em>Na</em></u>
Ca
<u><em>Mg</em></u>
Al
Zn
Fe
Sn
Pb
H
Cu
Hg
Ag
Pt
Au
Therefore Sodium is more reactive than Magnesium
The elements most likely to form more than one type of ion are thetransition metals
Boron’s chemistry is not typical of its group. is group 3A (13) shows the increasing metallic character from Al to Tl.
All Boron compounds are covalent whereas the other elements in group 3A (13) form mostly ionic compounds.
Except for Boron, the other elements of group 3A (13) show increasing metallic character from Al to Tl. But Boron is a metalloid.
Compared to the other elements in group 3A, boron has a lower reactivity in chemical terms (13)
The metalloid boron (B), as well as the metals aluminium (Al), gallium (Ga), indium (In), and thallium, are all part of group 3A (or IIIA) of the periodic table (Tl). In contrast to the other members of Group 3A, the element borax primarily forms covalent connections.

Answer:
Refer to the period table. Use the atomic mass for calculation. Multiply the atomic mass with the number of atoms. For example, Al2(SO4)3. (27 × 2) + (32 x 3) + (16 x 12) = molecular mass
