Differbetween
The transition metals are different from Alkali Metals in Group 1 in the following ways: • they have higher melting points; • they have higher density; • they are less reactive with water; • they react and form ions with different charges, but Group 1 metals only form 1+ ions.

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.
How do transition metals differ from metals in groups 1 and 2?
Some properties of transition metals set them apart from other metals. Compared with the alkali metals in group 1 and the alkaline Earth metals in group 2, the transition metals are much less reactive. They don't react quickly with water or oxygen, which explains why they resist corrosion.
What is the difference between transition metals and poor metals?
The poor metals are also referred to as post transition metals. ... They have high electronegativity and conductivity but softer texture compare to other metals. They are very soft more than the transition metals, but they cannot be cannot be classified as metalloids.
Why do transition metals have higher melting points than Group 1 metals?
In general, transition metals possess a high density and high melting points and boiling points. These properties are due to metallic bonding by delocalized d electrons, leading to cohesion which increases with the number of shared electrons.
Why are they called the transition metals?
The transition metals were given their name because they had a place between Group 2A (now Group 2) and Group 3A (now Group 13) in the main group elements. Therefore, in order to get from calcium to gallium in the Periodic Table, you had to transition your way through the first row of the d block (Sc → Zn).
What is so special about transition metals?
The transition elements are unique in that they can have an incomplete inner subshell allowing valence electrons in a shell other than the outer shell. Other elements only have valence electrons in their outer shell. This allows transition metals to form several different oxidation states.
What are the 14 transition metals?
Typically the elements of the post-transition metals include any metal in groups 13, 14, and 15 which are aluminum, gallium, indium, tin, thallium, lead, and bismuth.
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.
What are the main transition metals?
The first main transition series begins with either scandium (symbol Sc, atomic number 21) or titanium (symbol Ti, atomic number 22) and ends with zinc (symbol Zn, atomic number 30). The second series includes the elements yttrium (symbol Y, atomic number 39) to cadmium (symbol Cd, atomic number 48).
Why is aluminum a poor metal?
The 7 poor metals on the periodic table include Aluminum, Gallium, Indium, Tin, Thallium, Lead, and Bismuth. ... They have lower melting and boiling points than transition metals and they are softer and have a higher electronegativity. They have higher boiling points from the same metalloids in the same row.
Is zinc a poor metal?
Zinc is a soft metal (MH 2.5) with poor mechanical properties.
Why are the poor metals called poor metals?
Poor metals is considered the trivial name for such elements meaning Post-transitional metal name is preferred. Characteristics of poor metals are due to where they lay in the periodic table of elements. ... Their electronegativity and conductivity is also higher, but their texture is softer than usual metals.
