Question

periodic table basics practice
match the description to the element
atomic mass of 91.224
atomic mass of 114.818
atomic mass of 196.967
most common mass number is 207
most common mass number is 209
most common mass number is 167
most stable mass number is 247
most stable mass number is 98
most stable mass number is 252
elements: bismuth, curium, gold, einsteinium, lytbium, indium, lead, technetium, zirconium

Explanation:

To solve this, we match each description to the element using known atomic/mass numbers:

1. Atomic mass of 91.224 → Zirconium (Zr) (atomic mass ~91.224)
2. Atomic Mass of 114.818 → Indium (In) (atomic mass ~114.818)
3. Atomic Mass of 196.967 → Gold (Au) (atomic mass ~196.967)
4. Most Common Mass Number is 207 → Lead (Pb) (common mass number 207)
5. Most Common Mass Number is 209 → Bismuth (Bi) (common mass number 209)
6. Most Common Mass Number is 167 → Erbium (Er) (common mass number 167)
7. Most stable mass number is 247 → Curium (Cm) (most stable mass 247)
8. Most stable mass number is 98 → Technetium (Tc) (most stable mass 98)
9. Most stable mass number is 252 → Einsteinium (Es) (most stable mass 252)

Final Matches:

• Atomic mass of 91.224: Zirconium
• Atomic Mass of 114.818: Indium
• Atomic Mass of 196.967: Gold
• Most Common Mass Number is 207: Lead
• Most Common Mass Number is 209: Bismuth
• Most Common Mass Number is 167: Erbium
• Most stable mass number is 247: Curium
• Most stable mass number is 98: Technetium
• Most stable mass number is 252: Einsteinium
