Question

the criss - cross method involves exchanging the numerical value of the charges of two ions to determine the subscripts in the chemical formula of an ionic compound.
true
false
when applying the criss - cross method, the signs (+ or -) of the ionic charges are included in the resulting subscripts of the chemical formula.
false
true

Explanation:

The criss - cross method in chemistry for ionic compounds does involve exchanging the numerical values of the charges of two ions to get subscripts, but the signs of the charges are not included in the resulting subscripts.

Answer:

1. True
2. False
