Compounds formed from the last group -so Cu, Ag, Au. Copper and Silver in particular have quite a few compounds with valency 1. AgCl, AgBr, AgI etc. Cu (I) analogues also.
2 valence electrons are in iridium because iridium is a transition metal. Most transitions metal would have 2 valence electrons because the group before the transition metals are the alkaline-earth metals which contains 2 valence electrons in that group making the transition metals have 2 valence electrons.
Noble gases have a full valence shell with 8 electrons, while all other groups typically have fewer valence electrons. Transition metals have varying numbers of valence electrons depending on their position in the periodic table.
Boron group, transition metals, alkaline earth metals and alkali metals are listed in the Periodic Table are having less than four valence electrons
The group number of an element on the periodic table corresponds to the number of valence electrons it has. For main group elements (groups 1, 2, 13-18), the ones digit of the group number gives the number of valence electrons. For transition metals and inner transition metals, the number of valence electrons can vary.
For groups 1-2 the number of valence electrons is equal to the number of the group.For groups 13-18 the number of valence electrons is equal to the number of the group, but with numbering starting up from 3 (13), 4 (14) , etc. (transition metals excluded).
Different metals have different numbers of valence electrons. The alkali metals have 1. The alkaline-earth, transition, and inner transition metals have 2. Aluminum and those in its column have 3, tin and lead have 4.

Copper (Cu) has 2 valence electrons. It is located in the middle group of elements, called Transition Metals, and all transition metals have 2 valence electrons...hope that helped! =D
Transition metals have partially filled d-orbitals in addition to the s-orbital and p-orbital electrons, leading to more complex electron configurations compared to Group 1 and Group 2 metals, which only have s and p orbital electrons. Transition metals can have variable oxidation states due to the ability to lose different numbers of electrons from both the s and d orbitals. Group 1 and Group 2 metals typically only lose electrons from the s orbital.

Transition metals
Boron group, transition metals, alkaline earth metals and alkali metals are listed in the Periodic Table are having less than four valence electrons
one valence electrons
Alkali metals have 1 valence electron.
The valence electrons are added to d orbitals in the case of transition metals (or d block elements).
