Answer

Explanation:

Step1: Identify element uranium

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

Step2: Determine mass number

The isotope is written as (^{238}U^{+ 2}), and the mass - number is 238 (J).

Step3: Calculate number of neutrons

Neutrons = Mass number - Atomic number. So, (238−92 = 146) (M).

Step4: Calculate number of electrons

The atom is a (U^{+2}) ion. A neutral uranium atom has 92 electrons. Since it has a + 2 charge, it has lost 2 electrons. So, (92 - 2=90) (L).

Step5: Determine charge

The ion is (U^{+2}), so the charge is + 2 (C).

Step6: Classify the ion

A positively - charged ion is a cation (P).

Answer:

  1. K. 92
  2. J. 238
  3. M. 146
  4. L. 90
  5. C. 2
  6. P. cation
