Question

physical and chemical properties of metals and non metals? plz help me

Answer 1

metals are solids, often have metallic (silverish) glow, they are hard, they have crystal structure, have metallic bond, react with acids and bases if they dont have protective coating, in nature they can be found as oxides, they form salts with acids, they have high melting point, high evaporation point, they form bases...
nonmetals are liquids and gasses, they form covalent bond, can exist as oxides, some are inert, coloration varies, they have low melting and evaporation point (with exceptions), they react with acids and bases, they form acids...
did you have something like that in mind?

Answer 2

but mercury is liquid then how can we say that metals are solid

Answer 3

well mercury is only metal liquid, there are also solid nonmetals...

Answer 4

i need the physical &chemical properties with their exceptions

Answer 5

@Kryten plzz help me

Answer 6

then take better periodic table of elements with properties and there you have it... otherwise you can google, i dont know exactly what you need...

Answer 7

i will show you a ex:metals are hard(except sodium&potassium)
like that u can write

Answer 8

well you see that you know what you want so just continue to write properties you wish...
metals are solids (except mercury)...
this can go on and on, but only you know what properties you want to list so i dont see where is your problem...

Answer 9

let it be any property no problem

Answer 10

well than its just me doing your work, this is really simple task so just decide what properties you want to list and start, you could have already done that by now, if you are unclear about some property ask but i really dont see the problem...

Answer 11

Metals:

1) they are generally solid

2) Sonorous

3) Lustrous

4) Ductile

5) Malleable

6) high melting point and boiling point

7) High tensile strength

Answer 12

every thing has exceptions for example:
mercury is not solid but is a metal

lead is not ductile , malleable but it is a metal

Answer 13

physical property:
lustre
malleability
ductility
conductivity of heat
hardness
electrical conductivity
sonority
chemical property:
reaction with air
reaction with waterr
reaction with acids
reaction with bases
displacement reaction

i need about both metals and non metal

Answer 14

Also .. metals are generally rigid

Answer 15

@mathslover yes like that

Answer 16

Metals

lustre Yes
malleability yes
ductility yes
conductivity of heat yes
hardness yes
electrical conductivity yes
sonority yes
chemical property:
reaction with air to form oxide
reaction with waterr To form metal hydroxide
reaction with acids Zn + h2 so4 = Zn SO4 + h2
reaction with bases Zn + NaOH = Zn(OH)2 + Na
displacement reaction Zn + HCl = Zn(Cl)2 + H

Answer 17

i can do this for you ..

please prefer net for non metals

Answer 18

i need exception also

Answer 19

hardness-metals are hard (except sodium and pottasium)
like this i need

Answer 20

@Kryten can u say

Answer 21

here's one exception example is aluminium, he is amphoteric which means it reacts with acids and bases! google it up...

Answer 22

i want some more

Answer 23

I'm not sure if this is counted as displacement reaction:
displacement reaction Zn + HCl = Zn(Cl)2 + H
Well.. the equation is not balanced. It should be Zn + 2HCl = Zn(Cl)2 + H2
This is the reaction of metal with acid (HCl is an acid)

Answer 24

displacement reaction => more reactive (metal) displaces the less reactive (metal)
Example:
\[2Ag(NO_3)_{(aq)} + Cu_{(s)} -> Cu(NO_3)_{2(aq)} + 2Ag_{(s)}\]

Answer 25

\[\large{Cu^0 -> Cu^{2+} + 2 e^-}\]
\[\large{2 Ag^+ + 2 e^- -> 2 Ag^0}\]

Answer 26

this will help u

Answer 27

*reactivity series*

Answer 28

In that equation, copper, which is more reactive, displaces Ag in AgNO3 and forms Cu(NO3)2

Answer 29

got it @best.shakir ?
