Five protons makes this the element boron. The number of protons is the atomic number, and determines the identity of an element. This example would be the boron-12 isotope because it contains 5 protons and 7 neutrons.

The number of protons defines an element - the number of neutrons isn't needed to find the identity of the element. All ions and isotopes with 44 protons is ruthenium. However, with the information about the neutrons, we know the specific isotope: 101Ru.
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 of an element is determined by the number of protons.
0, zero, is defined as the identity element for addition and subtraction. * * * * * While 0 is certainly the identity element with respect to addition, there is no identity element for subtraction. The identity element of a set, for a given operation, must commute with every element of the set. Since a - 0 ≠ 0 - a, according to group theory, 0 is not an identity with respect to subtraction.
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.
0 and 1 are both identity element. 0 is the identity element of addition and its called addend while 1 is the identity element of multiplication it is called factor it can be neither multiplier nor multiplicand.
There is no individual sub-atomic particle that is responsible for the identity of an element. It is the way the electrons, protons and (neutrons) are arranged in an element that gives it it's identity.
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.
Zero.
Zero.
