Answer:
7. 4 neutrons.
8. 7 amu.
9. Proton.
10. Electron.
11. Neutron.
12. Protons and neutrons.
Explanation:
Hello!
In this case, given the atomic structure of the considered element, we can answer the questions as shown below:
7. Since the neutrons are placed into the element's nucleus, and they are neutrally charged, we see there are 4 neutrons:
8. Since the atomic mass of an element is computing by adding the number of protons and electrons, as this atom has three protons and four neutrons, its atomic mass is 7 amu.
9. Proton.
10. Electron.
11. Neutron.
12. Considering the given picture and the widespread atomic theories, we realize that inside the nucleus of an atom there are protons and neutrons.
Best regards!
