Answer 1

A Beryllium (Be) atom has 4 protons, 4 neutrons, and 4 electrons.

If you're looking at a model that has:

• Protons: If there are fewer than 4 protons, you need to add protons until you have 4. If there are 4 protons, no more are needed.
• Neutrons: If there are fewer than 4 neutrons, you need to add enough neutrons to make 4.
• Electrons: If there are fewer than 4 electrons, you need to add enough electrons to make 4.

To determine what needs to be added, please check the existing count for protons, neutrons, and electrons in the model you have. Based on that, you can choose appropriate responses.

• If you have:
  • 3 protons → add 1 more proton.
  • 2 neutrons → add 2 more neutrons.
  • 1 electron → add 3 more electrons.

Feel free to share the current counts present in your model if you need more specific guidance!
