What are physical properties of mercury?
What are physical properties of mercury?
Mercury has a melting point of -38.9oC, a boiling point of 356.7oC, and is the only metal to remain in liquid form at room temperature. Droplets of liquid mercury are shiny and silver-white with a high surface tension, appearing rounded when on flat surfaces.
What are 3 physical properties of mercury?

What does mercury element look like?
Mercury is the only elemental metal that is liquid at room temperature. (Cesium melts at about 28.5 °C [83 °F], gallium at about 30 °C [86 °F], and rubidium at about 39 °C [102 °F].) Mercury is silvery white, slowly tarnishes in moist air, and freezes into a soft solid like tin or lead at −38.83 °C (−37.89 °F).
What are the properties and uses of mercury?
Although many liquids could be used in pressure measuring devices, mercury is used because its high density requires less space. It is also a good conductor of electricity, so it is a useful component of electrical switches. Mercury is also used in dental fillings, paints, soaps, batteries, and fluorescent lighting.
What are the types of physical properties?
There are two types of physical properties: intensive and extensive . Intensive physical properties do not depend on how much of the object there is. For example, a small rock will be just as hard as a large rock. hardness, softness and speed ( quickness) are intensive physical properties.
What are the physical and chemical properties of the elements?
These properties include color, smell, freezing point, boiling point, melting point, opacity, viscosity, and density . Some elements have different physical properties depending on their chemical makeup as some elements can come in different chemical forms.
What determines the chemical properties of an element?
Elements are distinguished from one another by the numbers of these particles they have, and so each element has its own unique atomic number. The chemical properties of an element are determined by its number of electrons, but in a neutral atom , this is the same as the number of protons.
What is special about mercury the element?
A heavy, silvery d-block element, mercury is the only metallic element that is liquid at standard conditions for temperature and pressure; the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature .
