Question

name:
homework/part 3: binary ionic compound names - solve the puzzle!
instructions: working with your table partner at a level 1, review the partially completed table below in order to determine the method by which ionic formulas are written. after you believe you have \solved the puzzle\ complete the remainder of the table, and then in the space provided to you write the steps you took to name each compound.
note - the amount of steps you took can be longer or shorter than the numbers provided to you.
(the table above the text: columns are nonmetal (n (nitrogen), o (oxygen), f (fluorine), p (phosphorus), s (sulfur), cl (chlorine)) and rows are metal (li, be, na, mg, al, k, ca), with some cells filled with compound names like lithium nitride, beryllium oxide, etc.)

Explanation:

Step1: Identify Ion Charges

For metals (Li, Be, Na, Mg, Al, K, Ca) and nonmetals (N, O, F, P, S, Cl), determine their common ion charges. For example, Li⁺, N³⁻; Be²⁺, O²⁻; Na⁺, F⁻; Mg²⁺, P³⁻; Al³⁺, S²⁻; K⁺, P³⁻; Ca²⁺, S²⁻; etc.

Step2: Apply Criss - Cross Method

Use the criss - cross method to balance charges. For a metal (M with charge \(x^+\)) and nonmetal (X with charge \(y^-\)), the formula is \(M_yX_x\). Then name as "Metal + Nonmetal - ide".

Example for Li and O:

Li has charge \(+1\), O has charge \(-2\). Criss - cross: \(Li_2O\), named Lithium oxide.

Example for Li and F:

Li⁺ and F⁻, formula \(LiF\), named Lithium fluoride.

Example for Ca and Cl:

Answer:

To complete the table, use the steps of identifying ion charges and applying the criss - cross method to find formulas and then name the compounds as "Metal + Nonmetal - ide". The completed table (partial examples shown above) follows the pattern of balancing charges and using the " - ide" suffix for nonmetals.
