How many electrons are present in 6th period
After the 6s sublevel fills, the 4f sublevel is populated with up to 14 electrons.
This is followed by the 5d and the 6p sublevels.
The total number of elements in the sixth period is 32..
Which element is most likely to bend without breaking
CobaltCobalt is the element which is most likely to bend without breaking. Explanation: Elements can be of two type: metals and nonmetals. Metals are ductile that is the can be drawn into small wires and they can be bent without breaking.
How would you justify the presence of 32 elements in 6th period
In the sixth period (n = 6) of the periodic table, 6s, 4f, 5d and 6p orbitals are filled in the increasing order of the energy. Total 16 orbitals are available each of which contains a maximum 2 electrons. Thus, the sixth period can accommodate maximum 32 elements.
Why does the fourth period contain 18 elements but not 32
Answer. 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<4s<3d. ... So, maximum number of electrons found in the three orbitals is 9X2 = 18. Therefore, 4th period should have 18 elements.
Which element comes in 5th period of Chalcogen
This group is also known as the oxygen family. It consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and the radioactive element polonium (Po). The chemically uncharacterized synthetic element livermorium (Lv) is predicted to be a chalcogen as well.
Why is 3d in the 4th period
As it has been mentioned, electrons fill orbitals from the lowest energy, to the highest. … As you can see, the 4S orbital is filled BEFORE the 3D orbital as it has a lower energy, and therefore 3D has to be placed in the 4th row in the periodic table, after 4S.
What element is in period 4 Group 18
potassiumThe fourth period contains 18 elements beginning with potassium and ending with krypton – one element for each of the eighteen groups….Period 4 element.HydrogenRubidiumStrontiumYttriumZirconiumNiobium5 more columns
How many elements are present in 5th period
18 elementsThe fifth period contains 18 elements, beginning with rubidium and ending with xenon. As a rule, period 5 elements fill their 5s shells first, then their 4d, and 5p shells, in that order; however, there are exceptions, such as rhodium.

Why does the fifth period have 18 elements
The order in which the energy of available orbitals 4d, 5s and 5p increases is 5s<4d<5p and the total number of orbitals available are 9 and thus 18 electrons can be accommodated. In other words, in the fifth period, f orbitals are not filled.
How many elements of 6th period will have electron in 6d
32 elementsAnswer. The energy of the 6d subshell is even higher than that of the 7s subshell.In the 6th periods,electrons can be filled in only 6s,4f,5d and 6p subshells. Hence,the sixth periods of the periodic table should have 32 elements.
Which elements are in the same period
A period in the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor….Period 1.Group118Atomic # Name1 H2 He
What do all the elements in period 5 have in common
They only real thing that these elements share in common is the same principal quantum number, or main energy shell. For example, period 5 elements have their electrons filling up the to the fifth energy shell and period 6 elements have electrons that go the sixth energy shell.
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<4d<5p. The total number of orbitals available is 9. The maximum number of electrons that can be accommodated is 18, and therefore 18 elements are there in the 5th period.
Which element in period 5 is the most active metal
RubidiumRubidium is the first element placed in period 5 and is the most active metal.
