S2.3 The metallic model HL Flashcards
Transition elements
A metallic element located in groups 3–12 on the periodic table.
Why is copper used in
most electrical wiring
It is
one of the most electrically conductive metals
What are d-block metals and where are they typically found on the periodic table?
d-block metals have valence electrons in d orbitals, found in groups 3-12 of the periodic table. Examples include iron, copper, and tungsten.
Why do transition metals have high melting points and good electrical conductivity?
Due to delocalized d-electrons contributing to a stronger metallic bond and increased electron density, enhancing melting points and facilitating electrical conductivity.
How do d-block metals compare to s- and p-block metals in terms of electron configuration and properties?
d-block metals have complex electron configurations, allowing for multiple oxidation states and complex ions, leading to higher melting points and greater electrical conductivity compared to s- and p-block metals.
