Guida verificata passo dopo passo1
Understand the naming convention for molecular compounds: 'carbon tetraiodide' indicates one carbon atom bonded to four iodine atoms.
Recall that the prefix 'tetra-' means four, so the formula must contain four iodine (I) atoms.
Since there is only one carbon (C) atom, the chemical formula should have one C and four I atoms.
Write the formula by placing the element symbols with their respective counts: C for carbon and I4 for four iodine atoms, resulting in \(C I_4\).
Verify that the formula matches the name: one carbon atom and four iodine atoms correspond to carbon tetraiodide, confirming \(C I_4\) is correct.
