Answer is (1) - atomic number.

Atomic number is unique for an element. The elements in periodic table are organized according to the atomic number of elements. Another thing is atomic number is equal to number of protons of the element.

Mass number can be defined as the sum of proton number and neutron number. Although proton number is same for the atoms of same element, the neutron number can be varied.The atoms which has same atomic number but have different number of neutrons are called isotopes. Hence, mass number not enough for the identification of elements.

Only the neutron number is also not enough for the identification of elements. But if you have both mass number and the neutron number, then you can find atomic number by using mass number = proton number + neutron number equation. Then you can identify the element.

If you have total number of electrons of the element when it is in its neutral state you can identify the element because at neutral state number of electrons = number of protons (atomic number). But if only the valence electrons are given then you cannot find the element exactly because usually all elements in certain group have same number of valence electrons.

ANSWER

Theory of relativity.

In the year 1905 a famous mathematician and physicist named Albert Eisenstein gave a theory which shows relation between time and motion.

yes i am talking about special theory of relativity.

actually theory of relativity is divided in two parts

1. special theory of relativity

and

2. general theory of relativity.

✔special theory of relativity is based on the time and motion. 

there are two frame of references.

1. inertial frame of reference

and

2. inertial frame of reference.

in inertial frame of reference we talk about when body is moving with constant velocity.

and

in non inertial frame of reference we talk about unconstant velocity.

in the special theory it is used that the time and motion are relative. 

and there is a postulate that

✳ Nothing can travel faster than the speed of light that is.

299692458m/s and universe is limited at this speed so if a object moves near the speed of light then the time slows down for that object in order to maintain that speed.

Now

Theory of general relativity.

✔ after giving special relativity Einstein was not satisfied and wanted to know about how gravitational force can affect time.

so he gave general theory of relativity.

in this we talk about the gravitational force.

space time curvature 

fabric of cosmos and many more thing

in this Einstein showed that how gravitational force affect the time and also showed that the planets revolve around the sun because of the curve in space time
