1 answer

To complete the chart for a boron isotope, we need to know some fundamental facts about boron:

  1. The atomic number (Z) of boron is 5, which means it has 5 protons.
  2. The mass number (A) is the sum of the number of protons and neutrons. Common isotopes of boron include Boron-10 and Boron-11.
    • Boron-10 (B-10) has 5 protons and 5 neutrons (mass number 10).
    • Boron-11 (B-11) has 5 protons and 6 neutrons (mass number 11).
  3. In a neutral atom, the number of electrons is equal to the number of protons. Therefore, boron will also have 5 electrons.

For Boron-10:

  • Isotope name: Boron-10
  • Atomic #: 5
  • Mass #: 10
  • of protons: 5

  • of neutrons: 5

  • of electrons: 5

For Boron-11:

  • Isotope name: Boron-11
  • Atomic #: 5
  • Mass #: 11
  • of protons: 5

  • of neutrons: 6

  • of electrons: 5

You can choose either Boron-10 or Boron-11 based on your needs. Let me know if you need further information!
