Choose the correct alternative:
Among 4d, 4f, 5s, and 5p. The subshell having largest energy in a multielectron atom is 5s/4f.

Which is the largest integers among -7,-6,-5,-4 and -3?

Choose the correct answer : If 2P(A) = P(B) = 5/13, P(A/B) = 2/5, then P(A nn B) is :

Choose the correct answer : If P(A) = 0.8, P(B) = 0.5 P(B/A) = 0.4, find P(A nn B)

Calculate n, l, m and s for 4f and 2p electrons.

Calculate n, l, m and s for 4f and 3d electrons.

How many electrons will be present in the subshells having m _(s) value of - 1//2 for n = 4 ?

Assertion : Lanthanoids show a limited number of oxidation states whereas actinoids show a large number of oxidation states. Reason : Energy gap between 4f, 5d and 6s subshells is small whereas that between 5f. 6d and 7s subshells is large.

show that the poins :- P (4, 4), Q (2,-3), R (- 5,- 5) and S (- 3, 2) are the corners of a rhombus.

Find and correct the error. 4(x-5) =4x-5 .

Find and correct the error: (4x+5)/(4x) = 5
