What is the name of Pb4+?

lead(IV) ion
Thus, Fe2+ is an iron(II) ion and Pb4+ is a lead(IV) ion.

Is oxygen a cation or anion?

Halogens always form anions, alkali metals and alkaline earth metals always form cations. Most other metals form cations (e.g. iron, silver, nickel), whilst most other nonmetals typically form anions (e.g. oxygen, carbon, sulfur).

What type of atoms are found in pure silver?

How to balance an equation of a chemical reaction?

Instructions. To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above. Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported…

How do you write a formula for an ionic compound?

If you know the name of a binary ionic compound, you can write its chemical formula. Start by writing the metal ion with its charge, followed by the nonmetal ion with its charge. Because the overall compound must be electrically neutral, decide how many of each ion is needed in order for the positive and negative charges to cancel each other out.
