Question
3
Students were studying the first 20 elements on the periodic table. One
student found a diagram of a silicon nucleus. In the diagram the large
circle represents the nucleus. The rest of the particles are represented as
shown in the key.
Nucleus of a Silicon Atom (them image shows that inside of the nucleus there is 14 protons, 14neutrons, and 0 electrons)
Key
Proton
Neutron
Electron
Based on the diagram and the periodic table, which three statements
correctly describe a silicon atom?
A. Electrons are not present in the nucleus of a silicon atom.
B. There are 14 protons in the nucleus of a silicon atom.
C. Silicon atoms have no electrons.
D. A silicon atom should have 16 protons.
E. There are equal numbers of protons and neutrons in a silicon atom with a
mass number of 28.

Based on the information provided about the silicon atom and its corresponding diagram, the three correct statements that describe a silicon atom are:
A. **Electrons are not present in the nucleus of a silicon atom.**
(This statement is true; electrons orbit around the nucleus rather than being part of it.)
B. **There are 14 protons in the nucleus of a silicon atom.**
(This statement is true; silicon has an atomic number of 14, which means it has 14 protons.)
E. **There are equal numbers of protons and neutrons in a silicon atom with a mass number of 28.**
(This statement is true; a silicon atom has 14 neutrons and 14 protons, giving it a mass number of 28.)
The other statements:
C. **Silicon atoms have no electrons.**
(This statement is false; silicon has electrons, but they are not included in the nucleus.)
D. **A silicon atom should have 16 protons.**
(This statement is false; silicon has 14 protons.)
Thus, the correct statements are A, B, and E.
A. **Electrons are not present in the nucleus of a silicon atom.**
(This statement is true; electrons orbit around the nucleus rather than being part of it.)
B. **There are 14 protons in the nucleus of a silicon atom.**
(This statement is true; silicon has an atomic number of 14, which means it has 14 protons.)
E. **There are equal numbers of protons and neutrons in a silicon atom with a mass number of 28.**
(This statement is true; a silicon atom has 14 neutrons and 14 protons, giving it a mass number of 28.)
The other statements:
C. **Silicon atoms have no electrons.**
(This statement is false; silicon has electrons, but they are not included in the nucleus.)
D. **A silicon atom should have 16 protons.**
(This statement is false; silicon has 14 protons.)
Thus, the correct statements are A, B, and E.
