Question

consider this row in the periodic table of elements. evaluate which element(s) is/are most likely to conduct electricity. a lithium and beryllium b fluorine and neon c boron and carbon d lithium

Explanation:

Step1: Recall metal conductivity

Metals are good conductors of electricity. Lithium (Li) and Beryllium (Be) are metals (alkali and alkaline earth metals).

Step2: Analyze other options

• Option B: Fluorine (F) is a non - metal (halogen), Neon (Ne) is a noble gas. Non - metals and noble gases are poor conductors.
• Option C: Boron (B) is a metalloid (conducts poorly), Carbon (C) is a non - metal (poor conductor).
• Option D: Lithium alone is a metal, but option A has both Li and Be (both metals, good conductors).

Answer:

A. lithium and beryllium
