The correct answers are Orbits the nucleus in distinct shells / Have a negative electrical charge / May be lost, gained, or shared by atoms allowing chemical bonds to form.
Step-by-step explanation:
The image shows the model of an atom (unit of matter), in this, the electrons represented by blue dots are the only sub-particles outside the nucleus, while protons and neutrons are inside. This is because electrons are not part of the nucleus but orbit it. Also, these can be found in specific orbits or regions, known as shells. According to this, it is correct electrons orbit the nucleus in shells.
Moreover, electrons differ from other sub-particles because they are negatively charged, while neutrons are not charged and protons have a positive charge. Thus, it is correct electrons have a negative electrical charge.
Finally, their location in the atom and charge makes electrons to attract other atoms or ions and form chemical bonds. This occurs as different atoms or ions can shared electrons. Also, as part of this, atoms can gain or lose electrons. This means electrons can be gained, lost, or shared.
