Question

Transition metal elements are in the "d block" on the periodic table, because the electron configuration of every transition metal ends with electrons in "d" atomic orbitals. True False

Answer 1

TRUE :) ;D;D;D;D;D ;J

Answer 2

Answer: TRUE

Explanation: Transition elements are those which have electrons in the d orbitals in their outermost valence shell. They are also known as d block elements.

Thus Copper, Iron, Nickel etc are d block elements because their electrons are in the d orbital as shown-

Copper (Cu) = [Ar] 3d10 4s1

Iron (Fe) = [Ar] 3d6 4s2

Nickel (Ni) = [Ar] 3d8 4s2

Thus as shown in the electronic configuration above, the given stateent is true.
