Describe the process of transcription, in detail. - A) Initiation: RNA polymerase binds to the promoter, which is the beginning of the gene. inert atom - with a filled outer valence shell an inert atom is not able to gain or lose an electron and therefore is not able to participate in any chemical reactions. they are very stable Difference between hypothesis and theory - Hypothesis is an educated guess Theory is an explanation about something in the natural world. (has been repeatedly teste...

Why do only the outer electrons leave their orbit shells?  Only outer electrons leave their orbit shells because electrons farthest from the nucleus are more easily freed from their orbits due to a weaker electrostatic force. What is required to have a balanced (or stable) atom?  The number of electrons must equal the number of protons in order to have a balanced atom. List the capacity of each of the first four orbital shells of an atom.  Shell: #1 = 2 electrons; #2 = 8 electr...
