Structure of At...

An electron with energy $$12.09$$ eV strikes hydrogen atom in ground state and gives its all energy to the hydrogen atom. Therefore hydrogen atom is excited to __________ state.

Which of the following properties of atom could be explained correctly by Thomson's model of atom?

The spectrum of a molecule is so detailed that a molecule can be identified by its spectrum.

One requires 11eV of energy to dissociate a carbon monoxide molecule into carbon and oxygen atoms. The minimum frequency of the appropriate electromagnetic radiation to achieve the dissociation lies in:

Consider a $$p_{y}$$-orbital of an atom and identify correct statement.

According to Bohr's theory, the angular momentum for an electron of $${5}^{th}$$ orbit is:

In a Bohr's model of an atom when an electron jumps from n=1 to n=3, how much energy will be emitted or absorbed in erg?

The number of orbital having values of n = 4 and l = 3 :

Which of the following contains maximum number of atoms?
