Question

part iii. fill in the isotope names and any missing information on the chart. use your periodic table and the information provided. assume all atoms are neutral.

Explanation:

Step1: Recall atomic - related concepts

For a neutral atom, the number of protons = number of electrons. The mass number of an isotope is the sum of the number of protons and neutrons. The name of an isotope is written as "Element - Mass Number", where the mass number = number of protons+number of neutrons.

Step2: Fill in the missing information for Manganese

Mass number for the first Manganese isotope = 25 (protons)+17 (neutrons)=42. Name: Manganese - 42. For the Phosphorus isotope, mass number = 15 (protons)+15 (neutrons)=30. Name: Phosphorus - 30.

Step3: Fill in the missing information for Germanium

The first Germanium isotope has mass number = 32 (protons)+30 (neutrons)=62. Name: Germanium - 62. The second Germanium isotope has mass number = 32 (protons)+32 (neutrons)=64. Name: Germanium - 64.

Step4: Fill in the missing information for Palladium

The first Palladium isotope has mass number = 46 (protons)+48 (neutrons)=94. Name: Palladium - 94. The second Palladium isotope has mass number = 46 (protons)+51 (neutrons)=97. Name: Palladium - 97.

Step5: Fill in the missing information for Cesium

The first Cesium isotope has mass number = 55 (protons)+113 (neutrons)=168. Name: Cesium - 168. The second Cesium isotope has mass number = 55 (protons)+111 (neutrons)=166. Name: Cesium - 166.

Step6: Fill in the missing information for Iron

The names are already given as Iron - 53 and Iron - 56 which match the calculated mass numbers (26 + 27 = 53 and 26+30 = 56).

Step7: Fill in the missing information for Chromium

The names Chromium - 54 and Chromium - 56 match the calculated mass numbers (24 + 30 = 54 and 24+32 = 56).

Step8: Fill in the missing information for Iodine

For the first Iodine isotope, if we assume the mass number is not given but we know neutrons = 32. Let's assume a common iodine - 127 isotope where number of protons = 53. So this might be a wrong - formatted entry. Assuming correct proton number for iodine is 53, mass number for first Iodine = 53+32 = 85, Name: Iodine - 85. Second Iodine: mass number = 53+35 = 88, Name: Iodine - 88.

Step9: Fill in the missing information for the last two entries

If number of electrons = number of protons = 6, it is Carbon. For the first Carbon - like entry with mass number - 10 (not possible in normal sense, assuming it's a mis - write), if we consider correct mass number calculations, for the first one with 6 protons and assume correct mass number calculations, if neutrons are 4 (since mass number = protons+neutrons), mass number = 6 + 4=10, Name: Carbon - 10. Second one: mass number = 6+6 = 12, Name: Carbon - 12.
