Answer

Explanation:

Step1: Recall atomic - number concept

Ruthenium has an atomic number of 44. In a neutral atom, the number of electrons is equal to the number of protons, which is equal to the atomic number. So, the number of electrons and protons in ruthenium is 44.

Step2: Calculate number of neutrons

The mass - number of ruthenium - 101 is 101. The mass - number is the sum of protons and neutrons. Let the number of neutrons be $n$. We know that mass - number = number of protons+number of neutrons. So, $n=101 - 44=57$.

Answer:

  1. 44 electrons, 44 protons, and 57 neutrons
