Final answer:
The element at coordinates (8.58, 8.36) is Boron (B), considering that 8.58 is nearest to the atomic mass of Boron, and 8.36 is close to its atomic number of 5.
Step-by-step explanation:
The question asks us to identify the element represented by an atom located at coordinates (8.58, 8.36). We can use the periodic table to find the element that corresponds to these numbers. The coordinates appear to represent the atomic number and atomic mass of the element. In this case, the number 8.58 is closer to the atomic mass of Boron (B), which is 10.81. The number 8.36 does not directly correspond to the atomic number but considering that Boron has an atomic number of 5, which is the closest whole number to the given coordinates, we can infer that Boron is the correct answer. Therefore, the element in question is Boron represented by option A).
