Step 1: Write down the atomic numbers of the given elements.
The atomic number of Kr (Krypton) is 36, V (Vanadium) is 23, and I (Iodine) is 53.
Step 2: Determine how many more atoms are needed to reach a total of 200.
We are given three atomic numbers: 36 (Kr), 23 (V), and 53 (I). To find out how many more atoms we need, subtract the sum of these atomic numbers from 200: 200 - (36 + 23 + 53) = 200 - 112 = 88
Final Answer
The elements that have atomic numbers that add up to 200 and include Kr, V, and I are Kr, V, I, Br, and Sr.
