What element is mostly used in magnets, gold or cobalt?
Answer (3)
Answer : The correct option is, cobalt.
Explanation :
Magnet : It is defined as a type of material which produces the magnetic field. Or we can say that a material that has the property of attracting an iron piece and producing the magnetic field.
The elements iron, cobalt and nickel are usually used in the making of magnets.
Hence, the element used to make magnets is, Cobalt.
According to the properties of transition metals , the** element** which is mostly used in magnets is cobalt.
The **transition metals **are defined as the elements in which atoms are present whose d-sub-shell is partially filled .Due to which they give rise to cations with an incomplete d-sub-shell.
They are also defined as the elements which are present in the d-block of the periodic table, which includes groups from three to twelve.These elements are called transition elements as they show a transition between highly electro-positive group 1 and highly electro-negative group 17 elements.
They have characteristic properties due to which they can exist in variable oxidation states , form colored complexes and have **catalytic properties **as well.These elements are used as magnets as they are paramagnetic in nature.
Thus, cobalt is an element which is used in magnets.
