1. One example of an ionic compound is baking soda (NaHCO3) (also known as sodium bicarbonate). It is an ionic compound because ionic bonds are formed with metal and nonmetal atoms.
2. Specifically in “Tom's Simply White Toothpaste”, I found sodium fluoride. The reason I know that this is an ionic compound is because sodium is a metal, and fluorine is a non-metal.
3. Table salt is a common name for sodium chloride, chemically represented as NaCl. Sodium chloride is an ionic compound, in which one atom loses an electron, while the other gains
it.
4. water has a covalent bond because of the nature of oxygen and hydrogen -- they share electrons to attain stability, and their electronegativities are close enough for their bond to be considered covalent.
5. Two covalent bonds form between the two oxygen atoms because oxygen requires two shared electrons to fill its outermost shell. Nitrogen atoms will form three covalent bonds (also called triple covalent) between two atoms of nitrogen because each nitrogen atom needs three electrons to fill its outermost shell.
