→Move to: Bismuth (Bi) chemical element – Periodic Table
Why is Lead in Group xiv?
Practice you know, how many electrons can be accommodated in the first shell, 2nd trounce, tertiary shell, quaternary shell, etc…?
Here is the table showing the capacity of orbits to hold electrons.
Number of electrons in shells.
| Orbit / Crush (n) | Maximum no. of electrons this orbit can concur (two × northward two ) |
| K shell, north = 1 | 2 × 1² = ii |
| L beat, n = 2 | ii × 2² = viii |
| M trounce, n = iii | two × 3² = 18 |
| N trounce, n = 4 | 2 × 4² = 32 |
| . . . | . . . |
Thus,
- 1st shell can concur 2 electrons.
- 2nd beat out can concord 8 electrons.
- 3rd shell can hold 18 electrons.
- 4th shell tin can hold 32 electrons.
Now the atomic number of Lead (Lead) is 82.
Hence the Lead chemical element has electrons arrangement ii, eight, 18, 32, xviii, four.
This electron arrangement indicates that the outermost orbit of Atomic number 82 chemical element (Lead) has 4 electrons.
Hence, it lies in grouping 14.
Why is Atomic number 82 in Period six?
Permit me enquire y'all a question.
How many shells does pb have?
It'southward 6. Right?
Yous have already seen the bohr model of lead atom in the above tabular array.
From the Bohr model, it can be found that the number of orbits or shells in lead is 6. Hence, every bit lead has 6 orbits, it lies in menstruum 6 of the Periodic table.
Why is Atomic number 82 in p-block?
Before knowing this reason, first of all I want to enquire you a unproblematic question.
How can you determine the blocks-wise position of elements?
The simple reply: The elements volition prevarication in the s, p, d or f block volition completely depend upon the subshell in which the terminal electron will enter.
For example; the electron configuration of lead is [Xe] 4ffourteen 5d10 6s2 6p2.
So the final electron of atomic number 82 enters the p-subshell or p-orbital.
Hence, lead is the p-block element.
v Interesting facts about Lead
Interesting facts almost lead element are mentioned below.
- The concentration of lead in the earth's crust is effectually 114 ppm past weight.
- Lead is primarily obtained from its ore lead sulfide (PbS). atomic number 82 is also obtained from the ores of copper, silverish and zinc.
- Pb is ane of the elements that was discovered since ancient times.
- Lead is a soft metal and it can be cut with a knife also.
- Lead is a poisonous element. As well much pb in the human trunk tin can crusade nervous problems equally well as information technology as well affects organs similar kidney, centre, intestines, etc.
Backdrop of Lead
The physical and chemical backdrop of lead element are mentioned below.
Concrete properties of Atomic number 82
Concrete properties of lead are mentioned beneath.
- Lead is a solid metallic at STP and information technology has a metallic grey appearance.
- Lead is a poor conductor of electricity.
- Lead is ductile as well as malleable metal. That ways it can exist fatigued into sparse wires and thin sheets.
- There are many isotopes of lead, simply out of those isotopes the isotope 208Pb is the most abundant (having affluence of approximately 52.iv%).
- Lead element has a lower melting point of 327.4 °C. And its boiling signal is 1749 °C.
- The crystal structure of pb is FCC (i.e face centered cubic).
Chemical properties of Atomic number 82
Chemical properties of lead are mentioned beneath.
- When the lead is freshly cut, its surface is bluish gray. Simply if it is kept open in air, and then information technology reacts with oxygen and starts tarnishing (which forms a grey oxide layer on it).
- The electron configuration of lead is [Xe] 4ffourteen 5dx 6s2 6p2, which shows that the last electron enters the p-orbital. Because of this reason, it is classified as a p-cake element on the periodic table.
- In the compound form, lead exists in its most common oxidation states +2 and +4. Apart from these oxidation states, other oxidation states likewise exist.
- The 1st ionization free energy of lead is 7.417 eV.
- The electronegativity of atomic number 82 is 2.33 on the Pauling scale.
Uses of Lead
Uses of atomic number 82 are mentioned beneath.
- Most of the lead produced nowadays is used in manufacturing atomic number 82 batteries.
- Lead is also used in solder materials as well as in covering materials for cables.
- In ancient times, lead was used in plumbing (as it is non corrosive). Merely due to its toxicity it is not used nowadays.
- Lead is also used in manufacturing radiation shields, bullets, etc.
- Lead acts as a superconductor at temperatures below seven.2 Yard. [1]
