The element with an atomic number of 50 is tin (Sn). The atomic structure of tin can be described as follows:
Atomic Number: The atomic number of tin is 50, which means it has 50 protons in its nucleus.
Electrons: In a neutral atom, the number of electrons is equal to the number of protons. Hence, tin has 50 electrons orbiting around the nucleus.
Electron Configuration: The electron configuration of tin can be represented as [Kr] 5s^2 4d^10 5p^2. This configuration shows the distribution of electrons in different electron shells and subshells.
Energy Levels: Tin belongs to the fifth period of the periodic table, indicating that it has five principal energy levels or electron shells. The energy levels are filled in a specific order, with the first energy level holding a maximum of 2 electrons, the second holding a maximum of 8, the third holding a maximum of 18, the fourth holding a maximum of 32, and the fifth holding a maximum of 18 electrons.
Valence Electrons: The valence electrons are the electrons present in the outermost energy level of an atom. For tin, the valence electrons are in the 5s^2 and 5p^2 orbitals, which means it has 2 valence electrons.
Atomic Mass: The atomic mass of tin is approximately 118.71 atomic mass units (AMU). It is a weighted average of the masses of tin's naturally occurring isotopes.
In summary, tin (Sn) has an atomic number of 50, with 50 protons and electrons. Its electron configuration is [Kr] 5s^2 4d^10 5p^2, and it has 2 valence electrons in the 5s and 5p orbitals.
