Dmitri Mendeleev developed a chart like arrangement of the elements called the 1 . He stated that if the elements were listed in order of increasing 2 , their properties repeated in a regular manner. He called this the 3 of the elements. The arrangement used today differs from that of Mendeleev in that the elements are arranged in order of increasing 4___. Each horizontal row of elements is called a(n) 5. Each vertical column is called a(n) 6, or , because of the resemblance between elements in the same column, a(n) 7___.
In rows 4 through 7, there is a wide central section containing elements, each of which is called a(n) 8___. Rows 6 and 7 also contain two other sets of elements that are listed below the main chart. These are called the 9 and the 10, respectively. Each of the elements to the left of the stairstep line of the chart, is classified as a(n) 11. Each of the elements at the right side of the stairstep line is classified as a(n) 12. Each of the elements between these two main types, having some properties like one type and other properties like the other type, is called a(n) 13. Each of the elements in the column labeled IA or 1 is called a(n) 14. Each of the elements in the column labeled IIA or 2 is called a(n) 15. Each of the elements in column VIIA or 17 is called a(n) 16. Each of the elements in column VIIIA or 0 or 18 is called a(n) 17.

pre-sliced bread is a relatively recent development in baking technology. previous to that, it was always sold in a bakery in daily-made contiguous loaves with no wrapping, and was moderately perishable, usually being used with a day or two (which is why every bakery had a discounted “day-old” bread table.) therefore, pre-sliced bread would grow stale quickly. the hard crust provided a protective layer, and once the exposed dry slice left from the previous cut was removed, the interior was still soft.

what keeps bread soft is the moisture retained in the crumb (the light spongy part that’s not crust). the reason the crust develops is the surface of the dough gets exposed to hot dry air during baking which browns the outer layer and seals it, preventing all the moisture from escaping the dough. longer exposure to air will also eventually cause your bread to lose flavor and become stale.

people were used to cutting slices as they needed them and storing bread in a specially-made wooden or metal breadbox or pail with a lid to preserve it longer, but the first automatically sliced commercial loaves were produced on july 6, 1928, in chillicothe, missouri, using a machine invented by otto rohwedder, an iowa-born, missouri-based jeweler.[1] pre-sliced bread would indeed dry out, were it not for another 20th century technology: the plastic bag. bread could now be pre-sliced, and if the enclosing bag remains sealed as much as possible, the bread will remain soft and fresh for longer than if sitting unwrapped on a shelf or enclosed in a bread box that is not air-tight. sealed packaging meant bread could also be sold on store shelves and eliminate frequent trips to a bakery.

sealing bread in a plastic bag had another effect: the moisture in the loaf will re-distribute into the crust and soften it, which is sometimes more pleasing in a sandwich - especially for children whose teeth might not yet be strong enough to tear through a hard crust. a homemade loaf of bread can be sealed in a bag overnight and the crust will become soft like store-bought sandwich bread.

these were novel changes in how bread was produced and sold, which led to the coining of the phrase “the greatest thing since sliced bread.”
