The nonmetals in the periodic table. Metalloids The elements that border the stair-stepped line are classified as metalloids. The metalloids, or semimetals, have properties that are somewhat of a cross between metals and nonmetals. Metalloids tend to be economically important because of their unique...
78.1. THE PERIODIC TABLE 元素周期表 (图片可点击放大) In this section, we will explore the periodic table, which organizes chemical elements and provides valuable information about their properties and relationships. Understanding the periodic ...
What are metals? Learn the definition and different types of metals. See the reactivity and examples of metals present in the periodic table.
And if you look at the table as a whole, some big trends start to emerge that tell us how one element will react with another. Before we can see these trends, a quick chemistry recap might be good. First, metals react with nonmetals to form ionic compounds. The nonmetal atom takes ...
Answer to: Explain the definition of the metalloids and the nonmetals on the periodic table and list at least three examples for each of them. By...

There is a zig-zag line toward the right side of the periodic table that acts as a sort of border between metals and nonmetals. Elements on either side of this line exhibit some properties of metals and some of the nonmetals. These elements are themetalloids, also called semimetals. Metall...
Metals tend to be on the left side and in the middle. The periodic table really is an amazing thing. It so neatly and cleanly encapsulates how all of the elements which make up the world relate to each other. It isn’t just a handy educational aide, but it also should be considered ...
Just two strategies existed at the time to categorize these elements: separating them into metals and nonmetals or grouping them by an element's number of valence electrons (the electrons in the outermost shell). The first section of Mendeleev's book dealt with just eight of the known elements...
