Most elements of the periodic table are solid at room temperature. Some of them are gases at room temperature. The gas elements are all noble gases plus nitrogen, oxygen, fluorine, chlorine and hydrogen. There are only two elements with the liquid state among all elements....
Mercury(水银)水银(汞)在英语(english)中称为mercury，它来源于通讯神赫尔墨斯(Hermes)的名字，赫尔墨斯在罗马神话中叫墨丘利(Mercurius)在希腊神话中，地位非常高的神共有十二位，通讯神赫尔墨斯就是其中之一，他是主神宙斯的信使，是神话故事中出现次数非常多的一位神。赫尔墨斯机智狡猾，诡计多端，在神话...
They have a broad range of melting temperatures (e.g., mercury is a liquid at room temperature, gallium will melt in one’s hand, and tungsten has a melting temperature of around 3,400 degrees Celsius). The thermal and electrical conductivity of all metals is high compared to nonmetallic s...
Iron is a transition metal element, placing it in the same element family as gold, copper, and zinc. Its states of matter are determined by a combination of pressure and temperature, which solid iron occurs at the lower end of the temperature scale....
The only metallic element that is liquid at room temperature, mercury is a very shiny silver metal and is element number 80 on the periodic table. Its symbol is Hg, which stands for its Latin name Hydrargyrum, which means "liquid silver." Mercury has 34 isotopes, 6 of which are stable...
Gold is a metal element that has a symbolic representation of Au and the atomic number is 79. It is a precious metal and is used in making jewellery and is one of the monetary metals. It is solid at room temperature with high density, has a great softness, and is very bright. ...
Mercury, in its many forms, is not an element to mess with. In its pure form, mercury is an element -- symbol Hg on the periodic table, metallic, atomic number 80. It's a silvery substance that's liquid at room temperature, and it's naturally occurring. Some estimates put the amount...
Find the amount of heat energy needed to raise the temperature of 1000 grams (1 liter) of water 1 degree Celsius. The density of mercury, the only metal to exist as a liquid at room temperature, is 13.6 g/cm^3. What is this density in pounds per cubic inch? Calculate how many joule...
When liquid water evaporates, it becomes water vapor and enters the atmosphere. This process is essential to kickstart the water cycle, a continuous movement of water on, above and below the surface of the Earth. Evaporation occurs when heat from the sun causes water from oceans, rivers, ...
the most unique elements in the periodic table. The metal is only one of two elements that are liquid at standard temperature and pressure (stp). Mercury also has a very short temperature range between the freezing and boiling points. Mercury is the only transition metal with these properties....
