a) Ionization energy is the minimum amount of energy required to remove an electron from the last energy level of an isolated neutral atom form a positively charged ion in gaseous state
b) The ionization energy decreases from K to T; this is because of the addition of an extra energy level from K to T which decreases the nuclear attraction hence easy to remove an electron from the outermost energy level
Group I; they all have one electron in their outermost energy level;
c) Both K and T have giant metallic structures. K has smaller atomic/ionic size with strong metallic bonds that require higher amount of energy to break hence high melting and boiling point compared to T.
