An Identity element in multiplication is one that when you multiply a value by the identity element, that the original value is returned. The only identity element in multiplication is 1. If you multiply any value (other than infinity which is a special case of mathematics), the value returned will be 0. The identity element for addition is 0.

There is no such thing as an "identity of element". The identity element of multiplication, on the other hand, is the number 1.
An identity element is an element of a set which leaves other elements unchanged when combined with them. For multiplication, the identity element is 1 .
The identity property of multiplication asserts the existence of an element, denoted by 1, such that for every element x in a set (of integers, rationals, reals or complex numbers), 1*x = x*1 = x The identity property of addition asserts the existence of an element, denoted by 0, such that for every element y in a set (of integers, rationals, reals or complex numbers), 0+y = y+0 = y
No. The identity for addition is zero; the identity for multiplication is one.
1 is a whole number. It is the identity element with respect to multiplication but not addition.
