Concept introduction:
The metallic character is characterized by the tendency of metals to lose their outermost valence shell electrons. Greater the ease of electron removal, higher will be the electropositivity of the corresponding elements and vice versa.
The metallic character is characterized by the tendency of metals to lose their outermost valence shell electrons.
Down the group, the number of shells increases with the increase in the
Along the period, the electrons are added in the same outer shell and the effective nuclear charge increases due to which the electrons are attracted to the nucleus by strong electrostatic forces of attraction. Therefore the removal of the electron becomes difficult which results in the decrease of metallic character in a period.

The metallic character is characterized by the tendency of metals to lose their outermost valence shell electrons.
Down the group, the number of shells increases with the increase in the atomic number and the outermost valence electrons becomes farther from the nucleus and therefore can be removed easily. So the metallic character increases from top to bottom in a group.
Along the period, the electrons are added in the same outer shell and the effective nuclear charge increases due to which the electrons are attracted to the nucleus by strong electrostatic forces of attraction. Therefore the removal of the electron becomes difficult which results in the decrease of metallic character in a period.

- Predict the major products of the following organic reaction: NC Δ ? Some important Notes: • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. • Be sure to draw bonds carefully to show important geometric relationships between substituents. Note: if your answer contains a complicated ring structure, you must use one of the molecular fragment stamps (available in the menu at right) to enter the ring structure. You can add any substituents using the pencil tool in the usual way. Click and drag to start drawing a structure. Х аarrow_forwardPredict the major products of this organic reaction.

- Consider the following reactants: Br Would elimination take place at a significant rate between these reactants? Note for advanced students: by significant, we mean that the rate of elimination would be greater than the rate of competing substitution reactions. yes O no If you said elimination would take place, draw the major products in the upper drawing area. If you said elimination would take place, also draw the complete mechanism for one of the major products in the lower drawing area. If there is more than one major product, you may draw the mechanism that leads to any of them. Major Products:arrow_forwardDraw one product of an elimination reaction between the molecules below.
