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.
- 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.
- 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.
- For Te, the neutral atom has an equal number of protons and electrons, so it has 52 protons and 52 electrons.
- 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.
- 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.
- 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.
