The moment of inertia for CH4 can be calculated from the expression 2 8 3 I  mHR where R is the CH bond length (109 pm). Calculate the first 3 rotational energy levels for this molecule and indicate degeneracy of each rotational state.

How will the emission of an alpha particle affect the atomic number of an atom

An atom of sodium-23 (atomic number = 11) has a positive charge of +1. give this information, how many electrons does it have? how many proteins and neutrons does this atom have

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
