Question

state two reason
a) sulphur is a non metal
b) magnesium is a metal​

Answer 1

Answer:

Sulphur is a non-metal Magnesium is a metal (i) Poor conductor of heat and electricity

(i) Good conductor of heat and electricity

(ii) Neither malleable nor ductile

(ii) Malleable nor ductile

(iii) S + O2 →SO2 SO2 + H2O → H2SO3 (Sulphurous acid) Sulphur dioxide is acidic oxide. (iii) 2Mg + O2 →2MgO2 MgO + H2O → Mg(OH)2 (Magnesium hydroxide) Magnesium oxide is basic in nature.

Answer 2

Answer:

a) Sulfur is characterized as a non-metal because it is consistent with the 3 physical properties listed for nonmetals. It is a poor conductor of heat and electricity because the electrons are not free to move. It has a very high electronegativity because it is able to gain electrons easily.

b) Magnesium is a metal as it has 2 electrons in outer most orbit. Which it can easily donate to other aspirant elements.It is a metal cause it's got all the properties of a metal .
