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 is more of a nonmetal than ...

2017年5月19日 · It separates the metals from the non-metals The elements to the left of the staircase are metals (and metalloids) while the ones on the right are the non-metals Chemistry Science

2018年5月18日 · What does the bold stair step line on the periodic table mean? Chemistry The Periodic Table The Periodic ...

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, hence the name "periodic".

2016年5月21日 · The elements to the left of the stairs in the periodic table are called metals. The elements to the left of the stairs in the periodic table are called metals. However, within metals you have different families as it is indicated in the periodic table in the image below:

2017年1月15日 · Non metals do no have a uniform physical property. Many non metals are gases 1 is a liquid, others are solids. The solid non metals are amorphous. Unlike metals the non metal solid do not usually form a regular crystal shape. The solid non metals are generally soft and easily broken into pieces. However there are exceptions. Diamonds are a from of the nonmetal Carbon that forms very hard ...

2018年2月7日 · A, F. F. The line separates metals from nonmetals. Metals with low electronegativity that tend to form positively charged ions are on the left side of the line. Nonmetals with high electronegativity that tend to form negatively charged ions are on the right side of the line. A. metalloids are on both sides of the line. metalloids tend to have some metallic properties and some nonmetal ...

2017年6月26日 · These elements are called metalloids. A metalloid is an element whose properties are "in between" those of metals and nonmetals. For example, metals are excellent electothermal conductors, and nonmetals are non-conductors. Metalloids are described as semiconductors. These semiconductors play some major …

2017年4月5日 · Metals are found to the left of the stair step line. The elements on the stair step line are metalloids The elements to the right of the line are non metals. The elements to left of the line are metals. Metals have a relatively low electron negativity. The elements on the left of the periodic table are metals. Electron negativity decreases as …

2014年6月14日 · 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 line display increasing non-metallic behaviour. The elements to the lower left of ...
