Explanation:
Coinage metals -
The group 11 elements , i.e. , Copper , Silver , Gold are called the coinage metals .
These metals are quite soft and can be easily molded to form coins . This property is called as the property of malleability .
And due its soft nature , it can easily be used to make jewelry ,
Since , making jewels require the metal to be soft and flexible ,
Hence , gold is suited the best for this .
Solid, Liquid, Gas, and Plasma
Answer:
Mechanical Energy to Thermal Energy
When you strike a match, it moves through the air until it rubs against a surface. The rubbing produces the heat required to light the match. This is a transformation from mechanical energy to thermal (heat) energy.
Explanation:
Answer:
d orbital
Explanation:
Given that:-
The principal quantum number, n = 3
The acceptable values of azimuthal quantum number, l are:-
l = 0 , 1 , 2
l = 0 corresponds to s orbital which can accomodate 2 electrons.
l = 1 corresponds to p orbital which can accomodate 6 electrons.
l = 2 corresponds to d orbital which can accomodate 10 electrons.
<u>Thus, the highest energy orbital is: - d orbital</u>
