Question

Atomic radius Nbonding The radius of an atom describes the distance between the nucleus and the outermost electron. This distance is very small so it is often reported in picometers (101 m) or angstroms (10-10 m). One way of measuring the atomic radius is to observe the distanc between bonding atoms. The distance between the nuclei of the bonding atoms is equal to two times the atomic radius. This distance is called the bonding atomic radius and is shorter than the non-bonded radius. Theses radi are often called covalent radii, or metallic radii (for metals) Bonding Here is a graph of atomic radius plotted against atomic number. Study the graph and answer H ah ather eau the following questions Nudlel cannot get any closer o 1. Which elements have the largest radi, represented by the tallest peaks? 2. To which group in the periodic table, do these elements belong? 3. Which elements have the smallest radi, represented by the lowest points of the graph?_ 4. To which group in the periodic table, do these elements belong? 5. What is the general trend across the 3rd period (Na to Ne)? 6. Is this trend also seen in other periods? 7. How does atomic radius change down group 1 [Li to Fr) ? 8. Is this trend also seen in other groups? On the diagram of the periodic table at the end of this worksheet,use arrows to show the trend in atomic radi across a period and down a group.

can someone explain the graph to me I dont know how to read it to answer the questions
