Explanation:
The noble gases are found in group 18 of the periodic table with a complete valence electron shell. The elements of group 18 are chemically stable because their valence shells are filled.
However, Xenon differs from other noble elements because of its size and large number of electrons. The electrons in the outer shell are not tightly bound with the nucleus and thus, are somewhat free to part in reactions, this why xenon has so many compounds
Answer:
Q8) True
Q9) First ionization energy
Q10) Metal oxides
Explanation:
A common property of group one elements (alkali metals) is their combination with water to form basic solutions. E.g 2K(s)+2H2O(l)→2KOH(aq)+H2(g).
The distance of the outermost electron in the atom from the nucleus is inversely related to the first ionization energy. As the distance between the outermost electron and the nucleus in group 17 elements gets larger, the corresponding first ionization energies of elements in the group gets smaller.
Group 1 elements can combine with oxygen to give metal oxides. E.g 4K + O2 --> 2 K2O
