The identity of an isotope can be written as a symbol as follows: Complete the table below to describe the characteristics of an atom with this symbol: 131/53 1-

The symbol 131/53 I- represents an isotope of Iodine (I).

1. Atomic Number (Z): The atomic number is the number at the bottom, which is 53 in this case. This number represents the number of protons in the nucleus of the atom. So, this atom has 53 protons.

2. Mass Number (A): The mass number is the number at the top, which is 131 in this case. This number represents the total number of protons and neutrons in the nucleus of the atom. So, this atom has 131 protons and neutrons.

3. Number of Neutrons (N): The number of neutrons can be calculated by subtracting the atomic number from the mass number (N = A - Z). So, this atom has 131 - 53 = 78 neutrons.

4. Charge: The charge of the atom is represented by the superscript number next to the symbol. In this case, it is -1, which means the atom has one extra electron than protons, giving it a negative charge.

5. Number of Electrons: Since the atom is negatively charged, it has one more electron than the number of protons. So, this atom has 53 + 1 = 54 electrons.
