ISOLATION OF ELEMENTS - L12

L-12 to L-13

If 13 L 4 A 7 = 41 and 14 A 3L 12 = 54 , then 12 L 3 A9 = ?

What is the missing element in the Sequence represented by the question mark (?) P3 C,R5F, T8I, V 12 L,?

If l=LCM of 8!,10! and 12! and h=HCF of of 8!,10! and 12! then (l)/(h) is equal to

If a Set-A have 12 elements,then the number of subsets of A having atleast 3 elements is :

1.2 L of hydrogen and 1.12 L of chlorine are reacted. The composition by volume of mixture is

A natural atom of an element has 2K,8L, 9M and 2N electrons .The atomic number of element is :

An element has an atomic number 12. How may electrons will be present in the K, L and M energy shells of its atom ?

Why elements of group 12 are not considered as transition elements ?
