Question

How can the periodic table be used to predict the properties of the elements ?

Answer 1

Hint: All the elements of a gathering have similar chemical properties. In the event that we know to which group the element has a place we can know its chemical properties.
Ex: All the elements of gathering 1 show metallic property and they are profoundly electropositive .

Complete step by step answer:
The Periodic Table can anticipate the properties of new elements, since it sorts out the elements as per their atomic numbers.
Making new elements is anything but a straightforward cycle. Researchers utilize an atom smasher to crush light molecules into a flimsy metallic foil that contains heavier ions. They trust that the two atoms at the focal point of these molecules will circuit and shape a heavier core.
At the point when these substantial element structures, they are generally profoundly insecure. They rot so rapidly that we don't ordinarily see the element itself. All things being equal, we see a rot item. In that regard, even new elements aren't constantly 'found' straightforwardly. At times, researchers haven't combined enough of the element for us to understand what the element even resembles! By the way, we think about the element as known. We name them and show them the periodic table.
For instance, in \[\;2003\], researchers originally noticed element \[115\] (ununpentium, Uup) They assaulted americium\[ - 243\] with calcium-\[248\] particles and delivered four ions of Uup, which lived for short of what one fifth of a second.
\[{_{20}^{48}}Ca\; + \;\;\;95243Am\;\; - - - - - > \;\;\;\;{\;_{115}}^{288}Uup\; + \;3{\;_0}^1n\]
It took until September \[2013\] for the revelation to be affirmed, and around \[50\] particles have been integrated to date.
 We can foresee the properties of Uup in light of the fact that the Periodic Table coordinates element as per their nuclear number.
Uup shows up underneath bismuth in Group \[15\] of the Periodic Table. Its peripheral electron design is P, As, and Sb all structure mixes with oxidation conditions of \[ + 5{\text{ }}and{\text{ }} + 3\]. Bi will in general shape just \[ + 3\] mixes due to a wonder called the "dormant pair impact". We anticipate that Uup will proceed with this pattern and structure just \[ + 3{\text{ }}and{\text{ }} + 1\] oxidation states. Nitrogen(I) and bismuth(I) are known yet uncommon, yet ununpentium(I) might be more steady. Element \[\;114\] (flerovium) seems to have respectable gas-like properties. If so, ununpentium will probably frame \[ + 1\] cations, since Uup+ will have a similar electron setup as flerovium.

Note:
Periodic table itself had been made under the name of Atomic Number and as it is accepted and noticed, generally the nuclear number of an element characterizes its physical and compound properties. Accordingly it is fundamental to have an immediate connection between the periodic table and the properties of elements.
