Answer to Question #165840 in General Chemistry for tom

Question

How can you organize some data from the periodic table to correctly

identify the type of compound by bond type and create a set of rules for

naming and writing formulas based on the patterns in the names and

formulas?

Answer 1

Chemical properties of each element are determined by the element’s electronic configuration, and particularly by its outermost valence electrons. An element’s location in the periodic table is largely dependent on its electrons; the number of valence shell electrons determines its group, and the type of orbital in which the valence electrons lie in determines the element’s block. In addition, the total number of electron shells an atom determines which period it belongs to.

In the typical periodic table, each element is listed by its element symbol and atomic number. For example, “H” denotes hydrogen, “Li” denotes lithium, and so on. Most elements are represented by the first letter or first two letters of their English name, but there are some exceptions. Two notable exceptions include silver and mercury. The symbol for silver is “Ag” from Latin argentum, which means “gray” or “shining.” The symbol for mercury is “Hg” from the Latinized Greek hydrargyrum, which means “water-silver.”
