CW2 Q2-W1-Wen.-10/23

How are electrons arranged within an atom?

• Randomly throughout the atom

• In energy levels or shells around the nucleus

• Clustered together in the nucleus

• Only in the outermost region of the atom

What is the rule for filling electron shells in an atom?

• Electrons fill the outermost shell first.

• Electrons occupy the lowest available shell nearest the nucleus first.

• Electrons are distributed randomly across all shells.

• Electrons only fill shells that can hold 8 electrons.

• 1 electron

• 2 electrons

• 8 electrons

• 18 electrons
