If an atom has only one electron in its valence shell, how will it behave?

• A. The atom will act as a good insulator
• B. The atom will act as a good conductor
• C. The atom will be inert
• D. The atom will bond with other atoms easily

Answer: (B)

In an atom with only one electron in its valence shell, the behavior can be explained by considering its tendency to either lose, gain, or share electrons to achieve a stable electronic configuration. Particularly, atoms with a single electron in their outer shell are typically found in the alkali metal group of the periodic table, such as sodium or potassium. Such atoms have a strong tendency to lose their one valence electron in order to attain a full outer shell, which is a much more stable arrangement. When this electron is lost, the atom becomes positively charged, forming cations. This process facilitates the movement of electrons, allowing the atom to easily participate in the conduction of electricity. The fact that only one electron is present in the valence shell means that this atom can easily bond with other atoms, seeking to pair off its lone electron with electrons from other atoms. This characteristic also contributes to the atom's conductivity properties, making it a good conductor of electricity. Thus, the answer reflects the atom's capability to conduct electricity due to the ease of losing its single valence electron and forming strong metallic bonds with other atoms.
