Transition metals have a complex arrangement of electrons.
That is false
Transition metals:)
Transition metals have magnetic properties because they have unpaired electrons in their d-orbitals. These unpaired electrons can align their spins in response to an external magnetic field, which leads to the generation of a magnetic field. This property is responsible for the magnetic behavior of transition metals.
colour is the result of electron transitions.many complex ions of transition metals are coloured.Ti(H2O)63+ >> a complex with 1 d-electron - this has a red-purple colour.Cr(NH3)63+ >> a complex with 3 d-electrons - this has a purple colour.Ni(H2O)62+ >> a complex with 8 d-electrons - this has a green colour.Zn(NH3)42+ >> a complex with 10 d-electrons - this one has no colour and has no empty d-orbitals.
The valence electrons are added to d orbitals in the case of transition metals (or d block elements).
cations or positive ions, as transition metals lose electrons to achieve a stable arrangement
A sea of electrons. This is a very good description of the bonding in group 1 group 2 metals. A more advanced view for transition metals calls the sea of electrons an "sp electron gas" alongside covalent bonding involving d electrons. This accounts for the melting point trends in transition metals
That is false
The octet rule does not apply to transition and inner transition metals and to the first for or five elements in the periodic table.
All transition metals have valence electrons in a d-orbital.
by losing electrons
Transition metals:)
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.
The chemistry is about d electrons. They are all metals. The vast majority of their compounds are colored.
Transition metals.
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
