Question 1
Which transition metal is valued for its high electrical conductivity and resistance to corrosion, and is widely used for plumbing?
◦
iron◦
manganese◦
magnesium◦
cobalt◦
copperQuestion 2
Why do transition metals show a lot of chemical similarities within a given period?
◦
The valence s and p electrons affect their chemistry more so than the inner d and f electrons, which do not participate in bonding as easily.◦
The number of electrons within a given period varies only slightly and is sometimes identical because these metals have more than one ionic form.◦
All elements in a given period, including the representative elements, have a lot of chemical similarities due to the gradual increase in atomic number.◦
The transition metals always fill their s and p orbitals first before filling their d orbitals, which affects their chemistry.◦
None of these are correct.
