Write the atomic symbol for the isotope with each of the following characteristics: c. 25 electrons and 28 neutrons

Atoms consist of protons, neutrons, and electrons. The atomic number, which is the number of protons, determines the element's identity. In a neutral atom, the number of electrons equals the number of protons, balancing the charge. Understanding atomic structure is essential for identifying isotopes and their symbols.

Isotopes are variants of a chemical element that have the same number of protons but different numbers of neutrons. This difference in neutrons affects the atomic mass but not the chemical properties. For example, carbon-12 and carbon-14 are isotopes of carbon, with 6 and 8 neutrons, respectively. Recognizing isotopes is crucial for writing their atomic symbols.

The atomic symbol notation represents an element and its isotopes using the format A/Z Element, where A is the mass number (protons + neutrons) and Z is the atomic number (number of protons). For the given question, the atomic symbol can be derived by calculating the mass number from the provided electrons and neutrons, allowing for accurate representation of the isotope.
