The tantalum nitride films consist of a mixture of metallic tantalum, Î²-TaN 0.05, Î³-Ta 2 N and cubic/hexagonal TaN phases, their composition depending on both the ion dose and ion energy. 13. The kinetics of nitridation is characterised by two stages.
1) Chemical formula. It shows the types of atoms in the molecule, and, using subscripts, it shows how many of each type of atom is present. The Chemical formula of butane is C 4 H 10. 2) The structural formula of a molecule shows the symbol for every atom, and it shows every bond.3) The condensed structure of a molecule shows the symbol of every central atom and of each ligand or set of ligands bonded to a central atom.) A benzene molecule contains six carbon atoms in a closed ring, it has 3 carbon-carbon double bonds and six hydrogen atoms. Using ChemSketch or on a sheet of paper, write the chemical formula, condensed structure, structural formula, and line structure of benzene.
