Explain the purpose of staircase line. What type of elements are on ...
2017年3月6日 · The staircase line indicates the position of the metalloids in the Periodic Table. > The elements along side the line are metalloids. They have both metallic and nonmetallic character. The elements on the immediate right of the line tend to gain electrons more than lose them. They have relatively high electronegativities. Silicon, for example, is a semiconductor. It …
What does the zigzag line (the staircase) separate on the ... - Socratic
2017年5月19日 · The elements to the left of the staircase are metals (and metalloids) while the ones on the right are the non-metals
Are polyatomic ions molecular compounds or ionic compounds?
2014年2月1日 · Polyatomic ions are ions. However, the atoms in polyatomic ions are held together by covalent bonds. Compounds containing polyatomic ions are ionic compounds. The basic rule of thumb is ionic compounds take place between a positive ionic metal and a negative ionic non-metal. An ion from left of the metalloid staircase and an ion from right of the …
How are metalloids different from metals? - Socratic
2014年4月4日 · As you move from left to right across a row on the Periodic Table, elements gradually become more non-metallic in their properties. The staircase serves to indicate a cut-off point where the non-metallic properties are greater than the metallic properties. Metalloids are simply in the gray area betwen metals and non-metals.
What metalloids are in the periodic table? - Socratic
1 Answer. Ernest Z. Jun 14, 2014. The eight elements classified as metalloids are boron, silicon, germanium, arsenic, antimony, tellurium, astatine, and polonium. Metalloids occur along the diagonal stair-step between metals and non-metals. The stair-step line includes the elements from boron to astatine. The elements to the upper right of this ...
What metalloids are in period 5? - Socratic
2014年6月14日 · The two metalloids in Period 5 are antimony and tellurium. The eight elements classified as metalloids are in Groups 13 to 17 of the Periodic Table. Metalloids occur along the diagonal stair-step between metals and non-metals. The stair-step line includes the elements from boron to astatine. The elements to the upper right of this line display increasing non-metallic …
Why are metalloids located on the periodic table? | Socratic
2018年8月1日 · The non-metals are confined to the RIGHT of the Table as we face it; there are 15 or so; the blue triangle, and the yellow and gold Groups. The elements that are pea-green in colour, boron, silicon, germanium, arsenic, etc. are metalloids. And these have intermediate properties with respect to metals and non-metals.
What are the six metalloids on the periodic table? | Socratic
2018年4月11日 · The six metalloids are boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te). Some periodic tables include polonium (Po) and astatine (At) as metallo
The Periodic Table - Chemistry - Socratic
The Periodic Table. The periodic table is the table that indexes all chemical elements. It is arranged in order of atomic size (Hydrogen, then Helium, then Lithium, etc.) which is determined by the number of protons in the element. The table is subdivided into periods (rows) and groups (columns) of elements that share common characteristics ...
Metals and Nonmetals - Chemistry - Socratic
Metals, Nonmetals, and Metalloids are three classes of elements. The majority of elements in the periodic table are metals which are characterized by being shiny and solid (except Mercury) yet still malleable (or able to be molded and shaped). Metals are excellent conductors of electricity and heat. Nonmetals are primarily listed on the right side of the periodic table and have more …
