Describe the architecture of an atom correct answer: The atom is the basic building block that makes up all matter 1. Protons (+) charge 2. Neutrons (neutral) charge 3. Electrons (-) charge Protons and neutrons are in the center of the atom (nucleus), electrons orbit the nucleus in the electron cloud How do you know if an atom carries a charge? What is a charged atom called? correct answer: An atom will have a neutral charge if electrons = protons A positive charge if protons...

Equation for the number of stereoisomers and chiral centers # of stereoisomers=2^n n=chiral centers What does the direction of the electric field line represent? The movement of a positive test charge Oligodendrocytes and Schwann cells Produces myelin sheaths in the CNS and PNS function of myelin sheath to protect the neuron, provide insulation, and increase the speed of impulse transmission Another word for voltage is potential difference conductivity is ...
