Answer the following questions: * How is the chemical formula determined for an ionic compound?

* How are the ionic compounds named using IUPAC nomenclature rules?

1. The chemical formula is determined by first finding the positive charge, which is cation, and then finding the negative charge, which is the anion. The cation is writing first, than the anion.

2.An ionic compound is named first by its cation and then by its anion.

Explanation:

Just did it.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

they are both synthetic elements
