Where Are the Nonmetals Located on the Periodic Table


Nonmetals are located on the
upper right side
of the Periodic table (encounter to a higher place image).

Exception:
Hydrogen is a nonmetal which is located on the left top corner of the Periodic table.

Well, y’all have got the reply of “Where are Nonmetals located on the Periodic Table?” But there are lot more things that you lot should know about the nonmetals similar;

  • What exactly are the nonmetals?
  • How many nonmetals are there on the Periodic table?

  • Backdrop of nonmetals on the periodic tabular array

    • Physical properties of nonmetals
    • Chemical properties of nonmetals

Let us discuss all these topics quickly.

The uncomplicated answer:
“Not metals” are “non” the “metals”

Or in other words nonmetals are those elements which practise not possess the backdrop of metals.

Well, now allow me tell you the proper definition of nonmetals used in chemistry.

Nonmetals are the chemical elements which gain electron/southward during a chemical reaction and form a negative ion.

chemical properties of nonmetals to gain electron easily and forms negative ions

Non metals have exactly the opposite property than that of the metal.

In curt recall that;


  • Nonmetals are electrons gainers (nonmetals take/gains electrons)

Elements which bear witness these backdrop are known as Nonmetals.

I have discussed more than physics and chemical science properties of nonmetals in this article merely.

Stay tuned…

At present let us see the full number of nonmetals on the Periodic table.


There are
18 nonmetals
on the Periodic tabular array.

All these nonmetals are located on the upper right corner of the Periodic table (Hydrogen is located on the left meridian corner)

In the higher up image, the nonmetals are represented in yellow colour.

[Notation:
Astatine (atomic number 85) shows characteristics of nonmetals (halogens) equally well as metalloids. But many researchers have found that information technology shows more similar properties like that of nonmetals and hence Astatine (At) is considered equally a nonmetal (halogen) past many researchers] Source: HRW texts

Popular:   A Work Order Contains All of the Following Except

So on considering Astatine as a nonmetal, there are total
eighteen nonmetals
on the Periodic table.

And if Astatine (At) is excluded from nonmetals, and so there are full
17 nonmetals
on the Periodic tabular array.

Merely why is this number not exact?


Why is this number inexact?

The short respond:
Because at that place is no widely agreed definition of metals, nonmetals and semimetals.

A chemist may define nonmetals on the basis of chemical properties of the element, while a physicist may define nonmetals on the basis of density or atomic number.

And so we tin say that the total number of nonmetals on the Periodic table is 17 or 18.


Country of nonmetals at room temperature

Nonmetals are found in solid state, liquid state every bit well as gaseous state.

  • 11 non metals are in gaseous state at room temperature.
  • Bromine (Br) is a nonmetal which is in liquid state at room temperature.
  • Balance of the nonmetals are solids at room temperature.

Here is a complete list of all the eighteen nonmetals on the Periodic table.

Atomic number Symbol Proper noun of element

2 He Helium

The short answer: Fluorine
is a highly reactive nonmetal on the entire Periodic table.

where and which is the most reactive (highly reactive) nonmetal on the Periodic table

But why?

Don’t worry, I’ll tell you the reason behind this.

See, Atomic number of fluorine is 9. So information technology has ii orbits and seven electrons in its outermost orbit.

electron shell diagram or electron arrangement of fluorine element

Fluorine requires only i electron to complete the octet. And it is very like shooting fish in a barrel to gain one electron during a chemic reaction.

Also the atomic size of fluorine is very small. (Check this
Periodic table guide, for atomic size trend)

And because of its smaller size and need of but 1 electron, it has the highest electronegativity.

Electronegativity is nothing but a tendency to concenter the electron pair towards information technology.

electronegativity explained

Actually the halogens are the about reactive nonmetals, but we know that every bit we move down the group, the electronegativity decreases.

In other words, Fluorine is at the superlative of the halogen group and it has less atomic size plus information technology needs only one electron to complete the octet.

So it has highest electronegativity (information technology has maximum tendency to attract the electrons pair)

And considering of this, fluorine has a highest tendency to react with any other element to form a compound.

Even fluorine reacts with noble gas like xenon, and forms compounds like XeF4 (Xenon tetrafluoride) and XeF6 (Xenon hexafluoride)

Thus fluorine is highly reactive nonmetal.

(Notation: Noble gases have even smaller atomic size compared to halogens, but they take consummate octet. So they do not participate in whatever chemical reaction. Hence noble gases are chemically inert)

Well, now I’ll discuss the concrete and chemical backdrop of nonmetals.

Nonmetals have exactly the opposite characteristics that of the metals.

Let’southward get started with concrete properties.


Physical properties of nonmetals

#ane State: solid, liquid as well as gas

At room temperature, nonmetals are found in solid state, liquid state as well every bit gaseous state.

  • 11 non metals are in gaseous state at room temperature.
  • Bromine (Br) is a nonmetal which is in liquid country at room temperature.
  • Rest of the nonmetals are solids at room temperature.

#2 Little or no lusture

Nonmetals are generally not lustrous but few solid nonmetals have shiny lustrous surface (For example: Iodine have a lustrous surface)

#3 Poor usher of heat and electricity

Nonmetals do not permit estrus and electricity to laissez passer through them.

Hence they are poor conductors of heat and electricity.

#4 Brittle

Solid nonmetals are breakable in nature. That means they break easily when force is applied on them.

#5 Lower melting point and boiling point

Nonmetals have lower melting indicate as well as humid point and thus virtually of the nonmetals are gaseous at room temperature.

#6 Low density

Nonmetals accept lower density, hence they are light in weight.

#7 Not sonorous

Nonmetals practise non acquit sound. Hence they are non sonorous.


Chemic properties of nonmetals

#1 Valency

Nonmetals have 4 to eight electrons in their outermost orbit. (Halogens have 7 electrons and noble gases have eight electrons in outermost orbit)

#2 High electronegativity

Nonmetallic elements accept the higher trend to concenter the electron pair towards it during a chemical reaction.

Hence nonmetals are highly electronegative in nature.

#3 Gain of electrons

Nonmetals take 4 to viii electrons in their outermost orbit. Hence nonmetals show tendency to gain electrons during a chemical reaction to complete the octet.

#4 Forms acidic oxides

Nonmetals react with water and form acidic oxides.

#5 Adept oxidizing agents

Nonmetals are oxidizing agents considering they gain electron/s during a chemical reaction and become reduced.

Summary

So in the unabridged commodity, we accept discussed the definition or exact meaning of nonmetals and then we saw the position of nonmetals on the Periodic table.

Now you know that nonmetals are present on the upper right corner of the Periodic tabular array.

Then we likewise discussed that there are total 18 nonmetals on the Periodic tabular array (I also mentioned a list of these 18 elements)

And so we discussed almost the near reactive nonmetal on the Periodic tabular array (i.e Fluorine).

And finally we discussed the physical and chemical properties of nonmetals.

I hope this article “Where are Nonmetals located on the Periodic Table” has helped you in solving your doubts.
