How does temperature effect the state of matter?
because of the cold temprature that makes condensation 2. At low temperatures, most elements will be solid. At intermediate temperatures a few elements such as mercury will be liquid. At high temperatures most elements will be liquid, and higher again, all elements will be vapour.
In which state of matter do most elements exist?
solid
What are the four main physical elements of the universe?
Hydrogen, helium, oxygen, and carbon are the most abundant elements in the universe.
What family on periodic table has most poisonous?

No, more than three-fourths of the elements are metals. Love, Grahamcracker
What are fluorine's properties?
Fluorine is a pale-yellow, highly corrosive, poisonous, gaseous halogen element, the most electronegative and most reactive of all the elements.
Do elements contain chemicals?
Elements do not contain chemical, but chemicals contain elements. Elements are singular things with a set of properties all their own. There are currently 118 different known elements. Chemicals, which there are thousands of, are made up of two or more elements. Na is sodium(poisonous) and Cl is chlorine(also poisonous). When these two elements combine, you get NACl, which is table salt(not poisonous) and has properties completely different than the two individual elements.
Why does chlorine need to be stored in thick - walled containers?
It is a very dangerous chemical, it is a poisonous gas and it is one of the most reactive elements.

What element can be used as a slow poison?
What poison, specifically? Several elements are poisonous all by themselves ... arsenic, chlorine, and fluorine to name a few. Lead isn't acutely "poisonous", but it (and several other elements) cause heavy metal toxicity. Plutonium will kill you via ionizing radiation. And so on.
What is the Most toxic substance know in periodic table?
Elements are in the periodic table not substances, the most reactive of those elements would be Fluorine because of its electronegativity.
What are three elements of alkali metals?
All of the elements in the left-most period of the periodic table or alkali elements. Such as Li and Na.
