WebSolution 6: (i) Elements in the same group have equal valency. (ii) Valency depends upon the number of valence electrons in an atom. (iii) Copper and zinc are transition elements. (iv) Noble gases are placed at the extreme right of the periodic table. Question 7: Name two elements in each case: WebSince the 6s orbital with one electron is contracted, this electron is more tightly bound to the nucleus and less available for bonding with other atoms. The 4f and 5d orbitals expand, but can't be involved in bond formation since they are completely filled. This is why gold is relatively unreactive.

Why is gold unreactive when only one electron is in the outer shell?
