Question

please copy down the text you see below in your notebooks. modeling atomic structure. if you have ever broken a bone, the physician likely confirmed the location and extent of the injury with an x - ray. x - rays are powerful electromagnetic waves often used as a tool to see inside the body and diagnose problems without having to perform surgery. these waves are powerful enough to pass through the softer tissues of the body (such as skin), but not so powerful that the harder tissues (such as bones) easily absorb them. the resulting image shows in white the areas where the x - ray waves were absorbed. the areas where the waves passed through appear black. 1. describe what you see in the picture. 2. how can an x - ray image show differences between bones and soft tissues, such as muscle and lungs? how might the atoms that make up bones be different from the atoms that make up these soft tissues? divide your page into two columns and label the first column, \before instruction,\ and answer question #2. name the second column, \after instruction or end of unit.\ you will answer question #2 again after we finish the unit.

Explanation:

1. Since no picture is provided, cannot describe what is in the picture. For the second - part, X - rays are absorbed differently by bones and soft tissues. Bones, with higher density and more calcium atoms, absorb X - rays more, appearing white on the image. Soft tissues like muscle and lungs have lower density and fewer atoms that strongly absorb X - rays, so they appear black or darker. The atoms in bones (e.g., calcium, phosphorus) have different electron configurations and densities compared to those in soft tissues (e.g., carbon, hydrogen, oxygen in organic molecules).
2. As per the instruction, divide the page into two columns labeled "before instruction" and "after instruction or end of unit", and answer the question about X - ray differences in the "before instruction" column first and then again in the "after instruction or end of unit" column after the unit is completed.

Answer:

1. No picture provided, cannot answer.
2. Divide page into two columns as instructed and answer the X - ray difference question in the "before instruction" column first and then again in the "after instruction or end of unit" column after unit completion.
