The slightly positive charge on iron allows for what type of bond to oxygen that allows for transport from the lungs to the tissues
Ionic bonds in compounds, metallic bonds in the pure metal.
Molecule
Cations donate atoms to form an ionic bond.
Ionic bond. The metal (iron) gives up electrons to the non-metal (bromine.)
nonpolar covalent bond
it forms a triple bond
chemical bonding
When Iron and sulphur bond if forms the compound iron sulphide
Cations donate atoms to form an ionic bond.
Cations donate atoms to form an ionic bond.
Nonmetal atom create covalent bond
Ionic bond. The metal (iron) gives up electrons to the non-metal (bromine.)
double covalent bond
nonpolar covalent bond
Metals and non-metals
Iron atoms.
Iron would form ionic bonds with sulfur.
Normally Iron forms ionic bonds because it is a metal.
No bond at all, He has a complete outer shell
