Transition Elements Flashcards
Where are the transition elements in the periodic table?
Between the 2nd and 3rd group
Describe the conduction of transition elements
good conductors of heat and electricity
Describe transition elements
Dense, strong and shiny
Describe the reactivity of transition elements
Less reactive than Group 1 elements
Don;t react vigorously with water or oxygen
Describe the difference between transition elements and group 1 elements
transition elements are:
Much less reactive
Much denser, stronger and harder
Much higher melting points (except Mercury)
How many ions do transition metals have?
Usually more than 1
eg. Fe²+ or Fe³+
