Arrange the following in increasing order of metallic character: B,Al,Mg,K
Answers
Hint
- S block elements are more metallic
- Down a group , metallic character increases
K > Mg > Al > B
Answer:
B<AL<MG<K
Explanation:
Boron and aluminium belongs to p block factors and are organization thirteen factors while magnesium and potassium belongs to s block factors. Potassium belongs to organization 1 and magnesium belongs to organization 2. The metal individual of factors decreases from left to proper throughout a period. Thus, the metal individual of Mg is extra than that of Al.The metal individual of factors will increase down a set. Thus, the metal individual of Al is extra than that of B.
Considering the above statements, we get K > Mg.Hence, the appropriate order of metal individual is K > Mg > Al > B.From proper to left throughout a period, the metal individual will increase due to the fact the enchantment among valence electron and the nucleus is weaker, permitting an less complicated lack of electrons.
Metallic individual will increase as you circulate down a set due to the fact the atomic length is increasing.
Hence, accurate order might be .B<AL<MG<K
