Answer 1

Answer:

Radii of elements x y and z , each having an electrons in the ... the outermost shell of their atom: X melting =1.34. atomic radii =. 1.20. Y melting =1.54. atomic radii = 1.31

Answer 2

Answer:

From top to bottom down a group, electronegativity decreases. This is because atomic number increases down a group, and thus there is an increased distance between the valence electrons and nucleus, or a greater atomic radius. Important exceptions of the above rules include the noble gases, lanthanides, and actinides
