As temp increases, k also increases. </span>
Answer: Option (C) is the correct answer.
Explanation:
Periodic table has different symbols for individual elements which have been discovered till now. As a result, this periodic table is followed internationally as it is approved and doesn't have any flaws.
Thus, we can conclude that out of the given options, they are all recognized internationally is true about the symbols assigned to the elements.
Answer: copper I ion has a completely filed d-orbital.
Explanation:
The electron configuration of copper is
29Cu-[Ar] 3d10 4s1
The formation of Cu+ involves the loss of one 4s electron leaving a completely filled d subshell. Colour in transition metal complexes is generally attributed mostly to d-d transition. When bonded to ligands, the d-orbitals are no longer degenerate. They split into sets of orbitals depending on the nature of the crystal field. d-d transition is not possible when the d-orbitals are full hence Cu+ compounds are not coloured.
