Given the correct order of initials T (true) of F (false) for following statement. (I) Top positions of Lother-Mayer's atomic volume curve are occupied by Alkali metals (II) Number of elements presents in the fifth period of the periodic table are 32. (III) 2^(nd)I.P. of Mg is less than the 2^(nd) I.P. of Na. (IV) A p-orbital can take maximum of six electrons.

Give the correct order of initials T (true) or F (false) for following statements :- (I) If an ion has 2 electrons in K shell, 8 electrons in I . Shell and 6 electrons in M shell, then number of S electrons present in that element is 6 . (II) The maximum number of electrons in a subshell is given by 2n^(2) (III) If electron has magnetic quantum number -1 , then it cannot be present in s-orbital. (IV) Only one radial node is present in 3p orbital.

Which of the following options is correct regarding True (T) or False(F) nature of the statements. Statement - 1 : Angular momentum quantum number determines the three dimensional shape of the orbital . Statement-2 : No two orbitals can have exactly same wave function . Statement - 3 : The principal quantum number determines the orientation and energy of the orbital . Statement - 4 : The orbital wave function of one electron species which obeys Pauli's exclusion priniciple will be dependent on all the four quantum numbers .

Supposing that the pauli exclusion principal is not correct orbit can accammodate three electrons when are the respective atomic number of the second number of alkali metal and the first number of balogen family ?
