`NH_(3)`, is formed due to hydrolysis of Z which is similar to graphite structurally and Z is empirically similar to XN. What is the difference between atomic numbers of elements in Z?

The symbol of element with atomic number Z = 109

How is mass number (A) and atomic number (Z) of an element (X) represented?

If Z = 3, what would be the valency of the element? Also, name the element

In the graph between sqrtv and Z for the Mosley's equation, sqrtv=a(Z-b) , the Mosley's equation, sqrtv=a(Z-b) , the intercept OX is 1 on sqrtv axis. What is the frequency v when the atomic number Z is 52?

In modern periodic table, the element with atomic number Z = 118 will be:

The element with atomic number Z = 118 will be categorised as a:

In the graph between sqrt(v) and Z for the Mosley's equation sqrt(v) =a(Z-b), the intercept OX is -1 on sqrt(v) axis. What is the frequency when atomic number (Z) is 51?

Zr(Z=40) and Hf(Z=72) have similar atomic and ionic radii because of:

The three elements A, B and C with similar properties have atomic masses X, Y and Z respectively. This mass of Y is approximately equal to the average mass of X and Z. What is such an arrangement of elements called as ? Give on example of such a set of elements.

(X), (Y), (Z) are elements in third short period. Oxide of (X) is ionic, (Y) is amphoteric and (Z) is a giant molecule. (X), (Y) and (Z) will have atomic number in the order :
