Your teaching style is really excellent 👍👌

Atomic Mass Number (A)
The total number of protons and neutrons present in a nucleus of an atom is called mass number or atomic mass of an atom.
i.e A = Z + N
where , z = atomic number
N = number of Neutrons
Then atom is represented by X KO Power , where X = symbol of atom.
Representation of a Nucleus of an Atom:
The nucleus of an atom is represented symbolically as z X KO power A ,
where Z = atomic number
X= name of the element
A = atomic mass number
For example,
i ) Hydrogen nucleus, 1H¹
ii) Helium nucleus, 2 He⁴
iii) Oxygen nucleus, 8 0¹⁶
iv) uranium nucleus 92 U²³⁵ (foran isotope).

Is heat the sum of both kinetic and potential energy of molecules of body??

Heat is a sum of kinetic energy only; Because potential energy of particles or molecules can't produce thermal energy in a body.😊
