Which element is a liquid at room temperature?
There are two elements which are liquid at room temperature and they are Mercury (Hg) and Bromine (Br). Copernicium (Cn) might be liquid at room temperature but chemists are not sure about it.
How is water physically different then hydrogen and oxygen?
Water is a compound made up of two hydrogen atoms and one oxygen atom bonded together, while hydrogen and oxygen are elements. Water has different physical properties than hydrogen and oxygen, such as being a liquid at room temperature, whereas hydrogen is a gas and oxygen is a gas. Additionally, water has different chemical and bonding properties compared to hydrogen and oxygen individually.
Is bromine the element brittle?
No, Bromine is not brittle at room temperature, as Bromine is one of only two elements in the Periodic Table that is a liquid at room temperature.
Is bromine a liquid solid or gas?
Bromine is a halogen which can be a gas or liquid depending on the temperature. At room temperature bromine is a liquid metal.
Is silicon a solid at room temperature?
At room temperature the element silicon is a crystalline solid.If it was not a crystalline solid, the computer you have in front of you would not be possible (or would be much bigger and consume much more power).Do not confuse the element silicon with various compounds called silicone, which are oils and polymers that have silicon atoms in their molecules instead of carbon atoms, and can be either liquids or solids. There are also silicon compounds that are gases (e.g. silane, chlorosilane, fluorosilane, chlorofluorosilane).
What is the total number of elements in Group 17 that are gases at room temperature at standard pressure?
There are five elements in Group 17 (also known as the halogens) that are gases at room temperature at standard pressure: fluorine (F2), chlorine (Cl2), bromine (Br2), iodine (I2), and astatine (At2).
What are two types of gases?
halogens and noble
What gas is in group 7 of the peridic table?
Group 7 of the periodic table is known as the halogens group. The gases in this group are fluorine (F2), chlorine (Cl2), bromine (Br2), iodine (I2), and astatine (At2). Of these, fluorine and chlorine are diatomic gases at room temperature, while bromine is a liquid and iodine is a solid.
What halogens are liquids?
Bromine (Br) is a liquid at room temperature. It has a Melting Point of -7.3C and Boiling Point of 58.78C.
Which nongaseous compound can be made from two elements that are gases at room temperature?
Carbon dioxide
What are two chemical families on the periodic table?
alkali metals, halogens, noble gases
How is water derived from two gases?
When two or more elements are combined to make a compound, water, the new compound can have completely new properties(water is a liquid at room temperature ,while hydrogen and oxygen (elements in the water) are both gases at room temperature),or they can have similar properties to their elements
Is sulfur oxide a gas?
Sulfur forms two oxides SO2 and SO3 both these are gases at room temperature.
What periodic table group has similar chemical properties but different physical properties?
Group 17, the halogens have similar chemical properties. However, at standart temperature and pressure, two are gases, one is a liquid and two are solids.
What are the 2 halogens with the highest melting points?
Melting points increase with atomic weight for elemental halogens (the second-most right column in a periodic table). The heavier the atom, the harder to turn it into a liquid. The lightest halogens, such as Florine (F) and Chlorine (Cl) are gasses at room temperature, having "melted" and "boiled" at lower (colder) temperatures. The two heaviest halogens are Iodine (I) and Astatine (At). Astatine is very rare, but Iodine is common and is a solid at room temperature. The have the highest melting points of halogens. Remember, F down to At increase in melting points. F and Cl are gases, so they have low melting point. Br is a liquid, so it has a higher melting point. I and At are solids so it takes more heat to melt them.
What are two symbols for halogens?
We find five halogens in periodic table. Those are non metal elements. Fluorine and chlorine gases are examples.
List two substances that are solids two that are liquid and two that are gases at room temperature?
aluminum and rock juice and milk oxygen and nitrogen
