Answer

Explanation:

Step1: Recall element symbols

Oxygen is O, Hydrogen is H, Chlorine is Cl, Sodium is Na, Fluorine is F, Carbon is C, Helium is He, Nitrogen is N, Copper is Cu, Sulfur is S, Magnesium is Mg, Manganese is Mn, Neon is Ne, Bromine is Br, Phosphorus is P, Silver is Ag, Lead is Pb, Iron is Fe, Calcium is Ca, Potassium is K.

Step2: Fill in the chart for Sodium

The symbol for Sodium is Na, atomic number is 11, period is 3, group is 1.

Step3: Fill in the chart for Krypton

The symbol for Krypton is Kr, atomic number is 36 (not 79 as 79 is for Gold), period is 4, group is 18.

Step4: Provide atoms for each category

a. Halogen: Chlorine (Cl) b. Chalcogen: Oxygen (O) c. Alkali metal: Sodium (Na) d. Actinide series: Uranium (U) e. Lanthanide series: Cerium (Ce) f. Alkaline Earth metal: Calcium (Ca) g. Transition metal: Iron (Fe) h. Nobel gas: Krypton (Kr)

Answer:

Element Symbol Atomic Number Period Group
Sodium Na 11 3 1
