Explanation:

• For the elements:
• Germanium (Ge) is in Period 4 and Group 14.
• Radium (Ra) is in Period 7 and Group 2.
• Sulfur (S) is in Period 3 and Group 16.
• Oganesson (Og) is in Period 7 and Group 18.
• For the period - group combinations:
• Period 2, Group 14: Carbon (C).
• Period 4, Group 16: Selenium (Se).
• Period 6, Group 13: Thallium (Tl).
• Period 1, Group 18: Helium (He).
• For Tin (Sn):
• Atomic number: 50 (from the periodic table).
• Atomic mass (rounded): 119 (from the periodic table).
• Protons: 50 (atomic number = number of protons).
• Neutrons: \(119 - 50=69\).
• Electrons: 50 (in a neutral atom, number of electrons = number of protons).
• Tin is a metal (based on its position in the periodic table).
• Tin has a larger atomic radius than Copper (as we move down a group, atomic radius increases and Tin is in a lower - numbered group but higher period than Copper in a way that its overall size is larger).
• Tin has a smaller ionization energy than Copper (ionization energy generally decreases down a group and Tin is in a lower - numbered group than Copper in a way that its ionization energy is less).
• Tin is less electronegative than Copper (electronegativity generally decreases down a group and Tin is in a lower - numbered group than Copper in a way that its electronegativity is less).

Answer:

• Germanium (Ge): Period 4, Group 14.
• Radium (Ra): Period 7, Group 2.
• Sulfur (S): Period 3, Group 16.
• Oganesson (Og): Period 7, Group 18.
• Period 2, Group 14: Carbon (C).
• Period 4, Group 16: Selenium (Se).
• Period 6, Group 13: Thallium (Tl).
• Period 1, Group 18: Helium (He).
• Tin’s atomic number: 50.
• Tin’s atomic mass (rounded): 119.
• Protons in Tin: 50.
• Neutrons in Tin: 69.
• Electrons in Tin: 50.
• Tin is a metal.
• Tin has a larger atomic radius than Copper.
• Tin has a smaller ionization energy than Copper.
• Tin is less electronegative than Copper.
