Answer:

45) Ca < Co < Se

46) Te < S < O

Explanation:

These questions are talking about periodic trends. Here are some things to know about periodic trends:

Electronegativity

  • how well an element attracts an electron
  • increases left to right and bottom to top on the periodic table
  • noble gases are not included
  • fluorine is most electronegative element, Francium is least

Atomic Radius

  • the distance between nuclei
  • increases from right to left and top to bottom on the periodic table
  • the more electronegative an element is, the smaller it's atomic radius
  • Francium has the largest atomic radius while fluorine has the smallest

Ionization Energy

  • the energy required to remove an electron
  • directly proportional to electronegativity

Metallic Character

  • how closely an element's properties match those of a metal
  • directly proportional with atomic radius

Hope this helps :)
