An element ‘X’ with electronic configuration (2, 8, 2) combines separately with two

Monjur Alahi

An element ‘X’ with electronic configuration (2, 8, 2) combines separately with two
radicals, (NO3)– and (SO4)2–.
(i) Is ‘X’ a metal or a non-metal ? Write the nature of its oxide.
(ii) Write the formula of the compounds of ‘X’ formed by the combination of these
radicals. Are these compounds covalent or electrovalent ?

Assign the position of the element having outer electronic configuration

(i) Since n = 3, the element belongs to the 3rd period. It is a p–block element since the last electron occupies the p–orbital. There are four electrons in the p–orbital....

(a) Consider an arbitrary electrostatic field configuration. A small test charge is placed at a null point (i.e., where E = 0) of the configuration.

(a) Let the equilibrium of the test charge be stable. If a test charge is in equilibrium and displaced from its position in any direction, then it experiences a restoring...
