When determining the chemical name when two elements or polyatomic ions bond, the second step is to...Responseswrite the chemical name of each element and then alter the ending of the second element to "ide," unless the second element is a polyatomic ion. write the chemical name of each element and then alter the ending of the second element to "ide," unless the second element is a polyatomic ion. add prefixes before the name of each of the elements based on the subscript beside that element in the chemical formula no matter what type of bond it is.add prefixes before the name of each of the elements based on the subscript beside that element in the chemical formula no matter what type of bond it is.reduce (or simplify) the subscripts if it is an ionic compound if it is possible to do so. reduce (or simplify) the subscripts if it is an ionic compound if it is possible to do so. add prefixes before the name of each of the elements based on the subscript beside that element in the chemical formula only if it is a covalent compound.

When determining the chemical formula when two elements or polyatomic ions bond, the first step is to...Responseswrite the chemical name for each element and alter the ending of the second element to -ide. write the chemical name for each element and alter the ending of the second element to -ide. write the chemical symbols for each element and then write each element or polyatomic ion's oxidation number as the subscript for each chemical symbol. write the chemical symbols for each element and then write each element or polyatomic ion's oxidation number as the subscript for each chemical symbol. write the chemical symbols for each element and then write each element or polyatomic ion's valence number above its chemical symbol. write the chemical symbols for each element and then write each element or polyatomic ion's valence number above its chemical symbol. write the chemical symbols for each element and then write each element or polyatomic ion's oxidation number above its chemical symbol.

When determining the chemical formula when two elements or polyatomic ions bond, the second step is to...Responsesadd prefixes to the chemical name of each element based on the subscript by its chemical symbol. add prefixes to the chemical name of each element based on the subscript by its chemical symbol. "criss-cross" the number from the oxidation number so that is becomes the subscript on the opposite element or polyatomic ion in the compound. "criss-cross" the number from the oxidation number so that is becomes the subscript on the opposite element or polyatomic ion in the compound. reduce the oxidation numbers if it is an ionic compound. reduce the oxidation numbers if it is an ionic compound. use the the oxidation number so that is becomes the subscript on that same element or polyatomic ion in the compound.

Under Ionic or Covalent write in a "i" for ionic and a "c" for covalent.  The next two blanks under name write the name of the compound. For the name of the compound. If the metal requires a Roman numeral, then make sure you put the name of the cation(metal) and the Roman numerals without a space in between them and use parenthesis around the roman numeral, like this:   iron(II) or copper(I) Formula PbSO4ionic or covalent Name

Now you be writing the formulas from the name. For the formula of the compound.  When writing the formulas remember you are not able to use subscripts so write the compound as you would on paper but without writing subscripts.  for example ammonium carbonate would be made from thecation  NH4+1 and the anion CO3-2Formula = (NH4)2CO3Two nonmetals don't have ions, you will just be writing the formulas.  For example carbon dioxide would be CO2 name potassium oxalateionic or covalent formula

1. The metal ion (central ion) is listed first.2. Anionic ligands are written first in alphabetical order according to the first symbol of their formulae. Neutral ligands are written next in alphabetical order, according to the first letter of their formulae.3. The formulae of the entire coordination entity, whether charged or not, are enclosed in square brackets. If the coordination entity is negatively charged, the formula is preceded by the cation formula. When ligands are polyatomic (e.g., PPh3), their formulae are enclosed in parentheses. Ligand abbreviations are also enclosed in parentheses (e.g. bipy, acac etc,.).4. Write the cation first, followed by the anion.5. The total charge of a compound is zero, the charge of the cations should be balanced by the charge of the anion(s)Provide the formulae for the following coordination compounds and complexes. a. diamminedichloroplatinate (II) ANS: Answer 1 Question 8b. sodium amminetrichloroplatinate (II) ANS: Answer 2 Question 8c. sodium pentaaminenitrocobalt(III)     ANS: Answer 3 Question 8d. hexaamminechromium(III) tetrachlorocuprate(II)   ANS: Answer 4 Question 8e. trans-aquabis(ethylenediamine)iodocobalt(III) nitrate    ANS:
