Calculate the energy required to excite a particle in a cubic box of edge length 1Å from its ground state to its first excited state.
E1= h^2/8mL^2 = (6.63x10^-34)^2/8x9.1x10^-31 x 10^-10 x 10^-10 = 0.6038 x 10^-17J.

the ionization energy of hydrogen atom is 13.6 eV. The kinetic energy of the electron in hydrogen atom is a) 13.6 ev B0 31.6 eV C) 6.8 eV D0 21.7 eV
The energy of the electron in the nth Bohr orbit is En=-Z2*Rch/n2 Given, ionization energy of hydrogen atom = Rch=13.6 eV. Therefore, En=-(13.6 eV)*Z2/n2. Kinetic energy of the electron in...

The bond between an oxygen atom and a hydrogen atom would be categorized as:
a hydrogen bond
a non-polar covalent bond
an ionic bond
a polar covalent bond
A covalent bond is the force of attraction that holds together two nonmetal atoms that share a pair of electrons. One electron is provided by each atom, and the pair of...
