[1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.
This template also takes a variety of other parameters: |color-#= The template can take a color input for each do that is color-dot number (The default color is red) (overrides color-even and color-odd) |legend-color= This template can take a legend input to add to the legend.
Lay's Wow Chips were fat-free potato chips produced by Frito-Lay containing Olestra. They were first introduced in 1998, and were marketed using the Lay's , Ruffles , Doritos , and Tostitos brands.
The most common Lewis bases are anions. The strength of Lewis basicity correlates with the pK a of the parent acid: acids with high pK a 's give good Lewis bases. As usual, a weaker acid has a stronger conjugate base. Examples of Lewis bases based on the general definition of electron pair donor include: simple anions, such as H − and F −

The US Food and Drug Administration weighed in on the matter, and in 1975 they ruled Pringles could only use the word "chip" in their product name within the phrase: "potato chips made from dried potatoes".

In the early days, potato chips were distributed in bulk from barrels or glass display cases, [8] or tins, which left chips at the bottom stale and crumbled. [9] Laura Scudder started having her workers to take home sheets of wax paper and iron them into the form of bags, which were filled with chips at her factory the next day.
