Which element in Period 5 has the biggest size?
francium
As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest….Periodic Trends — Atomic and Ionic Radii.

Are transition metals the largest group?
Transition metals are the largest group of elements.
Which elements have the largest atomic size?
Cesium (Cs), tucked in the lower left hand corner of the table, has the largest known atoms. The atomic radius of Cs is given variously as 273.1 pm [1], 265 pm [2], 265.5 pm [3] or 260 pm [4].
What is the element in group 5 period 5?
The period 5 transition metals are yttrium (Y), zirconium (Zr), niobium (Nb), molybdenum (Mo), technetium (Tc), ruthenium (Ru), rhodium (Rh), palladium (Pd), silver (Ag), and cadmium (Cd)…. The Transition Metals.
Which is the longest and shortest period in periodic table?
sixth period
The sixth period contains 32 elements ( Cs to Rn ) and is also known as the longest period. The first period contains only two elements H and He and is known as the shortest period. The second period ( Li to Ne ) and the third period ( Na to Ar ) contain 8 elements each and are known as short periods.
Which transition metal has the highest oxidation state?
Manganese
Manganese, which is in the middle of the period, has the highest number of oxidation states, and indeed the highest oxidation state in the whole period since it has five unpaired electrons (see table below).
What group is transition metals?
Transition elements are the elements that are found in Groups 3-12 (old groups IIA-IIB) on the periodic table (salmon-colored block in the middle of the table).
What is the largest group of elements on the periodic table?
Group 1
Therefore our answer is Group 1 has the maximum number of elements and therefore the largest or longest group in the periodic table. Let’s learn a little bit about the Group 1 elements. They are called the alkali metals because on reaction with the water they form alkali metals.
What are the four transition metals on the periodic table called?
They are sometimes called the d-block elements, since in this region the d -orbitals are being filled in, and are also referred to as B-group elements since in most numbering systems of the columns on the periodic table the numerals of these groups are followed by the letter B. The period 4 transition metals are scandium (Sc), titanium (Ti),
What are the properties of the transition metals?
The transition metals, as a group, have high melting points. Their d orbitals become progressively filled as you move from left to right across the periodic table. Atoms of these elements have low ionization energies. Transition metals form colored complexes, so their compounds and solutions may be colorful.
Why are lanthanides and actinides called transition metals?
Also, the two rows of elements below the main body of the periodic table (the lanthanides and actinides) are special subsets of these metals. These elements are called ” transition metals ” because the electrons of their atoms make the transition to filling the d subshell or d sublevel orbital.
Which is the first element in period 5?
s-block elements. Rubidium. Rubidium is the first element placed in period 5. It is an alkali metal, the most reactive group in the periodic table, having properties and similarities with both other alkali metals and other period 5 elements.
