Answer 2

Answer: The isotope will be represented by symbol
`^(238)_(92)U` .

Solution:

The isotope of an element is represented by:

`^(A)_(Z)X`

X = Symbol of an element

Z = Atomic Number of that element = Total number of electrons or protons

A = atomic mass of that element = Z+ total number of neutrons

So the uranium isotope with atomic mass of 238 and atomic number of 92 will be written as:

`^(238)_(92)U`
