What period has 32?
Sixth period in the modern periodic table contains 32 elements..
RadonThe rows in which the elements arranged in the periodic table are called periods, There are 7 periods in the periodic table. The period 6 contains both metals and nonmetal elements. The only nonmetal in the period is Radon (Rn). The atomic number of Radon is 86.
Scandium is chemical element number 21 on the periodic table. Its symbol is Sc. Scandium is a metal in a group known as the transition metals. It is also a rare earth metal.
6th and 7th periods are called the longest period in the periodic table as it contains 32 elements in it because of inner transition elements.
How will you justify presence of 18 elements in 5th period and presence of 32 elements in 6th period?
When n=5,l=0,1,2,3 and 4. The order in which the enery of the available orbitals 4d,5s and 5p increases in 5s

How can you justify the presence of 18 elements in 5th period?
While filling 5th shell according to aufbau principle 5s,5p. 4d filled so 2 +6 +10 =18 electrons or elements are present in 5th shell.
What are bridge elements?
Bridge elements are elements that belong to period 2 of the periodic table. Bridge elements have acquired the name because of a unique characteristic that the elements showcase in the group. … Bridge elements show a cross or a diagonal relationship with the 3rd-period elements in the periodic table.
Who gave the law of octaves?
J.A.R. NewlandsLaw of octaves, in chemistry, the generalization made by the English chemist J.A.R. Newlands in 1865 that, if the chemical elements are arranged according to increasing atomic weight, those with similar physical and chemical properties occur after each interval of seven elements.
What are the 32 elements in Period 6?
A period 6 element is an element in the sixth period (row) of the periodic table. It contains 32 elements, beginning at Caesium and ending with Radon. The Lanthanides are part of this period….Atomic characteristics.Chemical element57LaLanthanumChemical seriesLanthanideElectron configuration[Xe] 5d1 6s231 more columns
How many elements are there in 6th and 7th period?
32 elementsPeriods 6 and 7 have 32 elements because the two bottom rows that are separated from the rest of the table belong to those periods.
Period 2Period 2 only has two metals (lithium and beryllium) of eight elements, less than for any subsequent period both by number and by proportion. It also has the most number of nonmetals, namely five, among all periods.
Which is the largest period in periodic table?
sixth periodThe sixth period of the periodic table is the longest period of the periodic table.
How many elements are present in 6th period explain?
32 elementsThe sixth period contains 32 elements, tied for the most with period 7, beginning with caesium and ending with radon. Lead is currently the last stable element; all subsequent elements are radioactive.
The period 6 transition metals are lanthanum (La), hafnium (Hf), tantalum (Ta), tungsten (W), rhenium (Re), osmium (Os), iridium (Ir), platinum (Pt), gold (Au), and mercury (Hg).
What element is in group 15 Period 6?
Nitrogen group element, any of the chemical elements that constitute Group 15 (Va) of the periodic table. The group consists of nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi), and moscovium (Mc).
Why does Period 4 have 18 elements?
Answer Expert Verified When n = 4, we find that in the orbitals 3d, 4s and 3p which are present in the outermost shells have energies in increasing order — i.e. 3p
HydrogenHydrogen is the lightest element. Dihydrogen, H2, is a colorless, odorless, tasteless gas.
