chemistry 1 (lp - 5061 - ck - 01) / molecular modeling and lewis structures evaluation\nin a molecular modeling kit, a black ball with 4 holes most likely represents the element _______.\n○ sulfur\n○ carbon\n○ magnesium\n○ hydrogen
Answer
Brief Explanations:
Carbon has a valence of 4, meaning it can form 4 covalent bonds. In molecular modeling kits, the number of holes in a ball representing an atom corresponds to its valence. A black ball with 4 holes is used to represent carbon as it commonly forms 4 - bond structures in molecules. Sulfur usually forms 2 bonds, magnesium forms 2 ionic - like bonds in many cases and hydrogen forms 1 bond.
Answer:
B. carbon
