Final answer:
The number of protons in an atom is equal to its atomic number. The number of neutrons in an atom can be calculated by subtracting the atomic number from the mass number. The number of electrons in a neutral atom is equal to the number of protons.
Step-by-step explanation:
The element represented by cd48111 is cadmium (Cd).
The number of protons in an atom is equal to its atomic number. The atomic number of cadmium is 48, so it has 48 protons.
The number of neutrons in an atom can be calculated by subtracting the atomic number from the mass number. Since the mass number is not given, we need additional information to determine the neutrons.
The number of electrons in a neutral atom is equal to the number of protons. Therefore, a neutral atom of cadmium would also have 48 electrons.
