The correct answer is
(A) (B) (C) (D)AP EAMCET 2009 Easy - Assertion (A) Boron has a smaller first ionisation enthalpy than beryllium.
Reason (R) The penetration of a \(2 s\)-electron to the nucleus is more than the \(2 p\)-electron hence, \(2 p\)-electron is more shielded by the inner core of electrons than \(2 \mathrm{~s}\)-electrons.AP EAMCET 2020 Easy - Copper matte is composed of ____AP EAMCET 2020 Easy
