周期表上,一个元素的基本信息一般都会被标注在元素的符号(symbol / chemical symbol)周围。 化学里的元素(element)基本可以分成 metal(金属) 与 nonmetal (非金属) 两类,金属元素又有一系列特别的 transition metals(过渡金属)。周期表上金属与非金属交界处又有着一系列具有特殊性质的元素,被称为 metalloid(准金属...

Metal or Nonmetal? Using the periodic table, classify each of the following elements as a metal or a nonmetal, and then further classify each as a main-group (representative) element, transition metal, or inner transition metal: uranium bromine strontium neon gold americium rhodium sulfur carbon ...

An introduction to the Periodic Table, discussing Mendeleev’s original periodic table. Metal, nonmetal, and metalloid elements are identified by location, and we compare and contrast the physical properties of metals and nonmetals. The Periodic Table: Crash Course Chemistry #4 ...
* Silicon (symbol Si) is a metalloid. It is a semiconductor, making it the principal component in many integrated circuits. Silicon dioxide is the principal constituent of sand. * Phosphorus (symbol P) is a nonmetal essential to DNA. It is highly reactive, and as such is never found in ...

You see metals every day.Aluminum foilis a metal. Gold and silver are metals. If someone asks you whether an element is a metal, metalloid, or non-metal and you don't know the answer, guess that it's a metal. What are Properties of Metals?
Non Metal Right of stair step line, an element that tends to be a poor conductor of heat and electric current; nonmetals generally have properties opposite to those of metals Metalloid Touching stair step, an element that tends to have properties of both metals and nonmetal ...
