State the guideline you can use to predict the formula of:
Cerrena [4.2K]

We can predict formula of ionic compounds by:

  • Take a look at where the elements are listed on the periodic table.
  • The amount of electrons that an element would need to gain or lose in order to resemble an atom of a nearby noble gas is one of the similarities that atoms in the same column as one another (group) tend to display.
  • Alkali metal group I ions have +1 charges.
  • Alkaline earth metals (group 2 ions) have a +2 charge.
  • Nonmetal group 6 ions have a charge of -2.
  • Halides in group 7 have a -1 charge.
  • The charges of the transition metals cannot be predicted in a straightforward manner.
  • Check out a table of charges (valences) to see potential values. The +1, +2, and +3 charges are most frequently employed in beginning and general chemistry courses.
  • Keep in mind that the positive ion is always stated first when writing an ionic compound's formula.

These are the few guidelines we can use to product formula.
