Question

practicing periodic table trends
directions: locate each element below on the periodic table and write which period and group that element is located in.

• germanium (ge) period: 4 group: 14
• radium (ra) period: 7 group: 2
• sulfur (s) period: 3 group: 16
• oganesson (og) period: 7 group: 8

directions: find and write the element for each of the following period/group combinations below using your periodic table.

• this element is in period 2, group 14:
• this element is in period 4, group 16:
• this element is in period 6, group 13:
• this element is in period 1, group 18:

directions: locate the element tin (sn) on the periodic table and answer the questions.

• what is tins atomic number? 50
• what is tins atomic mass (rounded to the nearest whole number)? 119

○ how many protons are in an atom of tin? 50
○ how many neutrons are in an atom of tin? 50
○ how many electrons are in an atom of tin? 69

• is tin a metal, non - metal, or metalloid? metalloid
• does tin have a larger or smaller atomic radius than copper?
• how does tins ionization energy compare to coppers? (larger or smaller?)
• is tin more or less electronegative than copper?

Explanation:

Step1: Locate elements on periodic table

• For Germanium (Ge): Period 4, Group 14.
• For Radium (Ra): Period 7, Group 2.
• For Sulfur (S): Period 3, Group 16.
• For Oganesson (Og): Period 7, Group 18.
• For Period 2, Group 14: Carbon (C).
• For Period 4, Group 16: Selenium (Se).
• For Period 6, Group 13: Thallium (Tl).
• For Period 1, Group 18: Helium (He).

Step2: Analyze Tin (Sn) properties

• Atomic number: 50 (from periodic table).
• Atomic mass (rounded): 119 (from periodic table).
• Protons: 50 (atomic number = number of protons).
• Neutrons: \(119 - 50=69\).
• Electrons: 50 (in neutral atom, electrons = protons).
• Tin is a metal (from periodic table classification).
• Tin has a larger atomic radius than Copper (as atomic radius increases down a group and Tin is in a lower - related position in terms of atomic structure trends).
• Tin has a smaller ionization energy than Copper (ionization energy generally decreases down a group).
• Tin is more electronegative than Copper (electronegativity trends).

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 (Sn) atomic number: 50.
• Tin (Sn) atomic mass (rounded): 119.
• Protons in Tin: 50.
• Neutrons in Tin: 69.
• Electrons in Tin: 50.
• Tin: metal.
• Tin vs Copper atomic radius: larger.
• Tin vs Copper ionization energy: smaller.
• Tin vs Copper electronegativity: more.
