Achlorine atom reacts with a sodium atom to form sodium chloride, nacl. a chlorine atom can also react with another chlorine atom to form a chlorine molecule, cl2. which statement best explains the behavior of chlorine in these two reactions? a) a chlorine atom can form a covalent bond with another atom by sharing electrons. b) a chlorine atom can form an ionic bond with another atom by accepting an electron. c) a chlorine atom can form ionic bonds by accepting an electron and covalent bonds by sharing electrons. d) a chlorine atom can form ionic bonds by sharing electrons and covalent bonds by accepting an electron.

If you mix chlorine lithium and nickel together which two elements would be the most reactive

The particle in a two-dimensional well is a useful model for the motion of electrons around the indole ring (3), the conjugated cycle found in the side chain of tryptophan. we may regard indole as a rectangle with sides of length 280 pm and 450 pm, with 10 electrons in the conjugated p system. as in case study 9.1, we assume that in the ground state of the molecule each quantized level is occupied by two electrons. (a) calculate the energy of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels. 9.27 electrons around the porphine ring (4), the conjugated macrocycle that forms the structural basis of the heme group and the chlorophylls. we may treat the group as a circular ring of radius 440 pm, with 20 electrons in the conjugated system moving along the perimeter of the ring. as in exercise 9.26, assume that in the ground state of the molecule quantized each level is occupied by two electrons. (a) calculate the energy and angular momentum of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels.

A2-kg bowling ball is 2.5 meters off the ground on a post when it falls. just before it reaches the ground, it is traveling 7 m/s. assuming that there is no air resistance, which statement is true?
