Ionic Compounds and Their Properties

The video tutorial explains how to write the chemical formula for tin(IV) fluoride. It begins by identifying the element symbols for tin and fluorine on the periodic table. Tin, being a transition metal, has a four-plus ionic charge, while fluorine, a non-metal, has a one-minus ionic charge. The tutorial demonstrates how to balance these charges to achieve a net charge of zero, resulting in the formula SnF4. The video concludes with a brief summary of the process.

What is the element symbol for tin, and what is its ionic charge?

• Sn, with a four-plus charge

• Ti, with a two-plus charge

• Sn, with a two-plus charge

• Ti, with a four-plus charge

Why is the compound formed between tin and fluorine considered ionic?

• Because both are metals

• Because they have the same charge

• Because tin is a metal and fluorine is a non-metal

• Because both are non-metals
