Electron shell

Electrons occupy specific orbits or shells, each with a fixed capacity. As the atomic number increases, these shells fill up from the inside out, following a specific order.

What can be said about the occupancy of electron orbits or shells?

• They can hold only one electron.

• They can hold one or more electrons.

• They can hold any number of electrons.

• They cannot hold any electrons.

Which of the following statements is true about electron shells?

• They can be occupied by protons.

• They can be occupied by electrons.

• They cannot be occupied by any particles.

• They can be occupied by neutrons.

What is true about the capacity of each electron shell?

• Each shell has a fixed number of electrons it can contain.

• Each shell can hold only one electron.

• Each shell can hold a variable number of electrons.

• Each shell can hold an unlimited number of electrons.

How do electron shells fill as the atomic number increases?

• From the outside in.

• All at once.

• From the inside out.

• Randomly.

What happens to electron shells as the atomic number increases?

• They become smaller.

• They fill up from the inside out.

• They fill up from the outside in.

• They remain empty.
