8. the atomic mass of the element in group 6, period 6: _____
9. the element with an atomic mass of 12: _____
10. the ion charge of all the noble gases: _____

Explanation:

Step1: Locate lithium in periodic table

Lithium (Li) is the 3rd element. So atomic number is 3.

Step2: Locate magnesium in periodic table

Magnesium (Mg) has an atomic mass of approximately 24.31.

Step3: Find lead in periodic table

The chemical symbol for lead is Pb.

Step4: Determine copper ion charges

Copper can have +1 and +2 ion - charges (Cu⁺ and Cu²⁺).

Step5: Identify alkaline - earth metal in fourth period

The alkaline - earth metal in the fourth period is calcium (Ca).

Step6: Find halogen in second period

The halogen in the second period is fluorine (F).

Step7: Locate element with atomic number 54

The element with atomic number 54 is xenon, symbol Xe.

Step8: Locate element in group 6, period 6

The element in group 6, period 6 is tungsten (W), with an atomic mass of approximately 183.84.

Step9: Find element with atomic mass of 12

The element with an atomic mass of approximately 12 is carbon (C).

Step10: Recall noble - gas ion charge

Noble gases have an ion charge of 0.

Answer:
