How is the chemical bonding within a molecule of carbon dioxide (CO2) different from the chemical bonding within a crystal of iron (Fe)?
O A. In an iron crystal, the atoms are joined by sharing electrons. In
carbon dioxide, atoms of carbon and oxygen are held together by
freely moving electrons.
B. In an iron crystal, the atoms are joined by their opposite electrical
charges. In carbon dioxide, atoms of carbon and oxygen are held
together by freely moving electrons.
C. In a carbon dioxide molecule, atoms of carbon and oxygen are
joined by their opposite electrical charges. In an iron crystal, the
atoms are held together by freely moving electrons.
D. In a carbon dioxide molecule, atoms of carbon and oxygen are
joined by sharing electrons. In an iron crystal, the atoms are held
together by freely moving electrons.
