Explanation:

Step1: Recall uranium's atomic number

Uranium (U) has an atomic number of 92, which is the number of protons. So for the atomic number and number of protons, the answer is 92 (K).

Step2: Identify mass number

The isotope is U - 235, so the mass number (number of nucleons) is 235 (J).

Step3: Calculate number of neutrons

Number of neutrons = Mass number - Atomic number. So, $235 - 92=143$ (M).

Step4: Determine number of electrons

In a neutral atom, number of electrons = number of protons. Since it's a neutral U - 235 atom for now, number of electrons is 92 (K).

Step5: Find charge

A neutral atom has a charge of 0 (A).

Step6: Classify based on charge

Since charge is 0, it is a neutral atom, which is an element (N).

Answer:

1. K. 92
2. J. 235
3. M. 143
4. K. 92
5. A. 0
6. N. element
