Structure of Atom - Result Question 12
####12. Based on equation
[NEET 2013]
(a) Larger the value of
(b) Equation can be used to calculate the change in energy when the electron changes orbit.
(c) For
(d) The negative sign in equation simply means that the energy or electron bound to the nucleus is lower than it would be if the electrons were at the infinite distance from the nucleus.
Show Answer
Solution:
- (c) The electrons has more negative energy in lower orbits that in higher orbit and also the electrons are more tightly bound in the smallest allowed orbit.
Energy of an electron at infinite distance from the nucleus is zero. As an electron approaches the nucleus, the electron attraction increases and hence the energy of electron decreases and thus becomes negative. Thus as the value of
