Question

solve the following question
I will mark you as brainlistlist​

Answer 1

1) Gold and silver

2) Silicon and Boron

3) Sodium and Potassium

4) Malleability

5) a) Ductile

b) Sonorous

c) Malleable

d) lustrous

e) solid (except mercury)

f) Hardness (except highly reactive metals and mercury)

6) Ductility is the property by virtue of which a metal can be drawn into thin wires. example- aluminium and copper are used to make conducting wires.

7) In Displacement reaction, a more reactive metal displaces less reactive metal from its place.

Example = Fe + CuSO4 ----> FeSO4 + Cu

:1:___ans__ gunmetal( an alloy made from a mixture of copper, tin and zinc__

__steel ( an alloy made from mixture of iron and carbon)

__bronze ( an alloy made from mixture of copper and tin )

__brass ( an alloy made from a mixture of copper and zinc )

:2:___ans__argsenic, for example, is a metalloid that has the visual appearance of a metal, but us a poor conductor if electricity, metalloids are generally semiconductor. the elements classified as metalloids are boron, sillicon, germanium, arsenic, antimony , tellurium, and polonium__

:3:__ans__sodium metals are soft enough to cut with knife the alkaline metals are the elements in group 1(1a) they are lithium ' sodium__

:4:__ans__the property by the virture of which they can be beaten in to thin sheets is called malleability and the property by the viture of which type can be drawn in to dutilly __

:5:__ana__metals are the lustrous 'malleble ' ductile ,good condition of heat and electricity.other properties including :_state metals are solids at room temperature with the expectations of murcury, which is liquid at room temperature ( gallium is liquidon hot days __

:6:___ans__ductillity is the physical propertie of a metal associated with the ability to be hammered thin or stretched in to wires without breaking .a ductile substance can be drawn in to a wire example:_moat metals are good examples of ductile materials including gold 'silver copper 'tetbium etc __

:7:___ans__desplacemt reaction is a chemical reaction in which a more rective element displace a leads rective element from its compound. both metals are non metals tale part in displacement reaction example :_reaction of iron nails with coffer sulphur solution __
