Question

the graph represents the atomic radii of the elements in period 3 on the periodic table of elements. use this information to answer the following questions. reading from left to right, the general trend for the size of nuclei by the elements in period 3 is a. increasing b. decreasing c. not changing

Explanation:

Step1: Analyze the graph

Looking at the graph, as we move from left (e.g., Na) to right (e.g., Ar) among Period 3 elements, the atomic radius values (on the y - axis corresponding to elements on the x - axis) are getting smaller.

Answer:

B. decreasing
