Transition Elements Flashcards
1
Q
What are the physical properties of transition elements?
A
Good conductors of both heat and electricity. They have high densities. They have high melting and boiling points (apart from mercury)
2
Q
What are the chemical properties of transition elements?
A
They’re much less reactive than alkali metals (group 1). This means they don’ react as easily with oxygen and water as alkalis do
3
Q
What are the compounds of transition elements?
A
Copper(II) sulfate is blue
Nickel(II) carbonate is pale green
Chromium(III) oxide is dark green
Manganese(II) chrloride is pale pink
4
Q
Why are transition metals so important in chemical industry?
A
They’re very good catalysts
5
Q
Why do transition element compounds have Roman number after them?
A
Because they can form more that 1 ion
