The relative penetrating powers of the alpha, beta and gamma particles should be described. Concept Introduction: The radiation is the radioactive source of energy having high frequency which can damage the human cell and is harmful for human beings. When a nuclei of an atom undergoes the radioactive decay, the particles like alpha, beta, and gamma are formed as by products. The radioactive decay of alpha particles results in decrease in the mass number by 4 and atomic number by 2 and decay of beta particles results in increase in the atomic number by 1 and no change in atomic mass number. Gamma decay is only release of energy and the number of proton remains the same.

Draw one product of an elimination reaction between the molecules below. Note: There may be several correct answers. You only need to draw one of them. You do not need to draw any of the side products of the reaction 'O 10 + x 也 HO + 义 Click and drag to start drawing a structure.

What are the angles a and b in the actual molecule of which this is a Lewis structure? H- :0: C=N: b Note for advanced students: give the ideal angles, and don't worry about small differences from the ideal that might be caused by the fact that different electron groups may have slightly different sizes. a = 0° b=0 X

A student proposes the transformation below in one step of an organic synthesis. There may be one or more products missing from the right-hand side, but there are no reagents missing from the left-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from the arrow. • Is the student's transformation possible? If not, check the box under the drawing area. • If the student's transformation is possible, then complete the reaction by adding any missing products to the right-hand side, and adding required catalysts, inorganic reagents, or other important reaction conditions above and below the arrow. • You do not need to balance the reaction, but be sure every important organic reactant or product is shown. + This transformation can't be done in one step.
