Final answer:
The metal atom in Pb3P2 is lead (Pb). The number of neutrons in Pb3P2 can be calculated by subtracting the atomic number from the mass number. For each isotope mentioned (206 Pb, 207 Pb, and 208 Pb), the number of neutrons is 124, 125, and 126 respectively.
Step-by-step explanation:
The metal atom in Pb3P2 refers to the lead (Pb) atom. Based on the information provided, we can determine the number of neutrons in Pb3P2 by subtracting the atomic number (number of protons) from the mass number. The atomic number of lead is 82, and the mass numbers of the isotopes mentioned are 206, 207, and 208. Therefore, the number of neutrons in Pb3P2 can be calculated as follows:
- 206 - 82 = 124 neutrons
- 207 - 82 = 125 neutrons
- 208 - 82 = 126 neutrons
