Consider the following statements:
I. The attractive interactions of an electron increases with increase of positive charge on the nucleus.
II. Due to the presence of electrons in the inner shells, the electrons in the outer shell will not experience the full positive charge of the nucleus .
III. The effect will be lowered due to the partial screening of positive charge on the nucleus by the inner shell electrons.
IV. The net positive charge experienced by the other electrons is known as effective nuclear charge .
The correct statements are
I. The attractive interactions of an electron increases with increase of positive charge on the nucleus.
II. Due to the presence of electrons in the inner shells, the electrons in the outer shell will not experience the full positive charge of the nucleus .
III. The effect will be lowered due to the partial screening of positive charge on the nucleus by the inner shell electrons.
IV. The net positive charge experienced by the other electrons is known as effective nuclear charge .
The correct statements are
View answer and explanation
Correct option: D
All of the above
Option D is correct because all the statements accurately describe the concepts of attractive interactions, inner shell electron shielding, and effective nuclear charge.

Which of the following pairs have identical values of e/m?
The correct de Broglie relationship is:
Assertion: Unlike sound waves, electromagnetic waves do not require medium and can move in vacuum.
Reason: The oscillating electric and magnetic fields produced by oscillating charged particles are parallel to each other and both are perpendicular to the direction of propagation of the wave. S-I: The orbital has maximum electron density along the y axis and its nodal plane is xz plane.
S-II : For a given atom, for all values of , the -orbitals have the same shape, but the overall size decreases as '' increases. S-I: Elements like and were discovered when their minerals were analysed by spectroscopic methods.
S-II: The element helium was discovered in the sun by spectroscopic method. In which one of the following, the number of protons is greater than number of neutrons but number of protons is less than the number of electrons?
