Final answer:

For each of the ions mentioned, the number of protons and electrons can be determined based on the ion's charge. The ions mentioned are Ba2+, Co2+, Zn2+, Te, Br-, and N3-.

Step-by-step explanation:

For each of the following ions, the number of protons and electrons can be determined by looking at the ion's charge.

  1. For Ba2+, the ion has a +2 charge, so it has 2 fewer electrons than the neutral atom of Ba. Therefore, it has 56 protons and 54 electrons. For Co2+, the ion has a +2 charge, so it also has 2 fewer electrons than the neutral atom of Co. Therefore, it has 27 protons and 25 electrons.
  2. For Zn2+, the ion has a +2 charge, so it also has 2 fewer electrons than the neutral atom of Zn. Therefore, it has 30 protons and 28 electrons.
  3. For Te, the neutral atom has an equal number of protons and electrons, so it has 52 protons and 52 electrons.
  4. For Br-, the ion has a -1 charge, so it has 1 more electron than the neutral atom of Br. Therefore, it has 35 protons and 36 electrons.
  5. For Rb+, the ion has a +1 charge, so it has 1 fewer electrons than the neutral atom of Rb. Therefore, it has 37 protons and 36 electrons.
  6. For N3-, the ion has a -3 charge, so it has 3 more electrons than the neutral atom of N. Therefore, it has 7 protons and 10 electrons.
