On the basis of this definition,
scandium and zinc
do not count as transition metals – even though they are members of the d block. Scandium has the electronic structure [Ar] 3d

What is not a transition element?
Hence it is not a transition element. Therefore, the correct answer is option (D) i.e.
Potassium
. Note: It should be noted that transition elements have a lesser number of electrons in the outermost shell so they all act as metals.
What are non-transition metals?
The non-transition elements are the main-group elements that
are s and p block elements
for example Alkali metals like sodium (Na), Potassium (K) etc, alkaline earth metals like magnesium(Mg), Strontium (Sr) etc., Chalcogens like Oxygen, Sulphur, Halogens like Chlorine, Bromine etc.
Which of the following is not considered a transition metal?
Zn, Cd, and Hg
are normally not considered as transition metals as they contain completely filled d – orbitals in their elementary and commonly occuring ions.
Why is not a transition metal?
Aluminium sometimes is or is not counted as a post-transition metal.
It has a well shielded [Ne] noble gas core rather than the less well shielded [Ar

Is Potassium a transition metal?
At high pressure the alkali metals potassium, rubidium, and cesium transform to metals that have a d1 electron configuration, becoming
transition metal-like
. … They also have significant implications for the hypothesis that potassium is incorporated into Earth’s core.
Is gold a transition element?
Gold is a chemical element with symbol Au and atomic number 79. Classified as a
transition metal
, Gold is a solid at room temperature.
What is the difference between metals and transition metals?
Metals are the largest category of elements and they are characterized by their appearance: usually they possess a silvery shine, they are solid (except for mercury), they are malleable and they
conduct electricity and heat
. Transition metals are the elements that belong to the middle of the periodic table.
Why is Aluminium not a transition metal?
Aluminum is the second element in the thirteenth column of the periodic table. It is classified as a post-transition metal and a
“poor metal
“. Aluminum atoms contain 13 electrons and 13 protons. There are 3 valence electrons in the outer shell.
What are the difference between transition and non transition metals?
Transition metals are in the d-block and have valence electrons in the d-orbital’s. They can form multiple
oxidation
states and form different ions. … Inner transition metals are in the f-block and have valence electrons in the f-orbital’s.
Why CD is not a transition metal?
, Cd, and Hg are not regarded as transition elements
because their d-subshell is totally full-filled
and thus they do not show much tendency to accept electrons in their 3d orbitals. So they are in their ground state as well as their most common oxidation state (+2).
Which of the following is classified as a transition metal?
The period 4 transition metals are
scandium (Sc)
, titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), and zinc (Zn).
Which one is the transition element?
In general,
any element which corresponds to the d-block of the modern periodic table (which consists of groups 3-12)
is considered to be a transition element. Even the f-block elements comprising the lanthanides and the actinides can be considered as transition metals.
Is Iodine a transition metal?
Iodine is one of the heaviest non-radioactive elements in the Periodic Table classified as a
non-metal
, and it is the largest, the least electronegative, and the most polarizable of the halogens.
How do you identify transition metals?
Early transition metals are
on the left side of the periodic table from group 3 to group 7
. Late transition metals are on the right side of the d-block, from group 8 to 11 (and 12 if it is counted as transition metals).
What metal has properties like tin?
Answer:
gallium, indium, thallium, lead, and bismuth
.
