Name the final acceptor of electrons in ETC.

Name two elements that have two electrons in their outermost shells

Name the final products of anaerobic respiration?

An electron microscope uses electron accelerated by a voltage of 50kV. Determine the de-Broglie wavelengths associated with the electrons. If other factors (such as numerical aperture etc) are taken to be roughly the same how does the resolving power of electron microscope compare with that of an optical microscope which uses yellow light?

What is the number of valence electrons in the atoms of an element having atomic number 13 ? Name the valence shell of this atom.

Name two factors which influence electron affinity.

What is the general name of the elements having 8 electrons in the valence shell of their atoms ?

The electron in a hydrogen atom make a transtion n_(1) rarr n_(2) where n_(1) and n_(2) are the priocipal quantum number of the two states . Assume the Bohr model to be valid . The time period of the electron in the initial state is eight time that in the final state . The possible values of n_(1) and n_(2) are
