Choose the correct statement(s)

The maximum positive oxidation state shown by any element is equal to the total number of electrons (s and p) in valence shell

The maximum oxidation state shown by elements in a group is also known as group oxidation number

Group oxidation number is the most common or most stable oxidation state for a particular element

All the elements in a group form some compounds in which they exhibit their group oxidation number

A curved surface of radius R separates two medium of refractive indices mu_1 and mu_2 as shown in figure Choose the correct statement(s) related to the virtual image formed by object O placed at a distance x, as shown in figure.

Virtual image is formed for any position of O if `mu_2 lt mu_1`

Virtual image can be formed if x gt R and `mu_2 gt mu_1`

Virtual image is formed if x lt R and `mu_2 gt mu_1`

none of these

The probability of finding the electron in the same-sized volume around x = z=0, y=a is the same i.e., `1 xx 10^(-5)`

The probability of finding the electron in the same -sized vlume around x=y=0, z=a is zero

The probability at the second site if the electron were in a `P_(z)` obital is zero.

The probability at the second site if the electron were in a `P_(z)` orbital is the same i.e., `1.0 xx 10^(-5)`

If `(vec(A) xx vec(B)). vec(C ) = vec(A). (vec(B) xx vec(C ))= 0, vec(A), vec(B) and vec( C)` are coplanar

any vector can be split into more than two components

Pseudo vector also having direction

Pseudo vector has no direction
