2. 192/76N: Nitrogen-192 has 76 protons, 116 neutrons, and 76 electrons.
3. 142/58Ce: Cerium-142 has 58 protons, 84 neutrons, and 58 electrons.
The world of atomic structure is truly fascinating! Each atom consists of protons, neutrons, and electrons in different numbers based on the element. Let's dive deeper into the specific atoms mentioned above.
Nickel-62 (62/28Ni)
Nickel-62 has an atomic number of 28, which tells us it contains 28 protons. To calculate the number of neutrons, we subtract the atomic number from the atomic mass (62 - 28 = 34). Since the atom is electrically neutral, it also has 28 electrons.
Nitrogen-192 (192/76N)
Nitrogen-192 is composed of 76 protons, 116 neutrons (192 - 76), and 76 electrons. The atomic number of 76 defines its unique characteristics.
Cerium-142 (142/58Ce)
Cerium-142 is characterized by its 58 protons, 84 neutrons (142 - 58), and 58 electrons. It showcases the beauty of atomic structure in action.
Understanding the composition of atoms provides insight into their properties and behavior. The intricate balance between protons, neutrons, and electrons shapes the world around us. To explore more about atomic structure, continue your learning journey!
