On cooling to "X" on the line AE the alloy begins to reject or deposit practically pure Iron. consists of diatomic molecules in elemental form Stainless steel is an example of a combination of interstitial and substitutional alloys, because the carbon atoms fit into the interstices, but some of the iron atoms are replaced with nickel and chromium atoms. (D) increasing number of unshared pairs of electrons Curious how close to pure iron you can get. 8. Please contact the submission author. Atomic Number 9. CCl4, CO2, PCl3, PCl5, SF6 Which of the following does not describe any of the molecules above? As we said Steel is an interstitial alloy, not a substitutional. The electronic configuration of, Q:Atoms of Ca-38 and Ca-40 differ with respect to number of The carbide form can be iron carbide (Fe3C, known as cementite), or it can be a carbide of an alloying element such as titanium.
