Answer

Explanation:

Step1: Identify atomic number of Te

From periodic table, atomic number of tellurium (Te) is 52.

Step2: Determine number of protons

Atomic number = number of protons. So number of protons is 52.

Step3: Calculate number of neutrons

Mass - number = 130, atomic - number = 52. Number of neutrons = mass - number - atomic - number = 130 - 52=78.

Step4: Calculate number of electrons

It is a 2 - minus anion. Neutral Te has 52 electrons. So number of electrons = 52 + 2=54.

Step5: Define number of nucleons

Nucleons are protons + neutrons. Mass - number represents number of nucleons. So number of nucleons is 130.

Answer:

  1. A. 52
  2. A. 52
  3. D. 78
  4. B. 54
  5. E. 130
