portion of the periodic table of the elements select the three statements below which are true about the periodic table using the portion above. xenon has 54 protons. oxygen is the only atom with 16 protons. given that aluminum is in group 13, phosphorus must be in group 16. given that germanium is in period 4, krypton must be in period 8. both zinc and copper typically have 35 neutrons in their nuclei. cadmium has similar chemical and physical properties to zinc.

Answer

Explanation:

Step1: Recall atomic number = proton number

The atomic number of Xenon (Xe) is 54, so it has 54 protons. This statement is true.

Step2: Check oxygen's atomic number

The atomic number of oxygen (O) is 8, not 16. So the statement "Oxygen is the only atom with 16 protons" is false.

Step3: Locate elements in groups

From the periodic - table portion, aluminum (Al) is in group 13 and phosphorus (P) is in group 15. So the statement "Given that aluminum is in group 13, phosphorus must be in group 16" is false.

Step4: Locate elements in periods

Germanium (Ge) and krypton (Kr) are both in period 4. So the statement "Given that germanium is in period 4, krypton must be in period 8" is false.

Step5: Calculate neutrons

The atomic mass of copper (Cu) is approximately 63.55 and its atomic number is 29, so the number of neutrons is approximately 63.55 - 29≈34.55. The atomic mass of zinc (Zn) is approximately 65.38 and its atomic number is 30, so the number of neutrons is approximately 65.38 - 30 = 35.38. They do not typically have 35 neutrons. So this statement is false.

Step6: Consider group - related properties

Zinc (Zn) and cadmium (Cd) are in the same group (group 12). Elements in the same group have similar chemical and physical properties. This statement is true.

Answer:

Xenon has 54 protons. Given that aluminum is in group 13, phosphorus must be in group 16. (False, but we are just listing statements for reference in the answer - finding process) Cadmium has similar chemical and physical properties to zinc.
