What two properties of metal makes it suitable for over head cables?
Metalloids and non-metals make it useful for electrical-------------------------------------------------------------------------Metals are used in wiring to transfer the electrical energy around your home and non-metalic materials i.e plastics are used as insulators.
Why is the range of densities much greater among the nonmetals than among the metals?
Nonmetals contain about equal numbers of solid and gas or liquid elements. The subatomic particles that make up gases and liquids are more spread out and less compact than in solids. Therefore, gases and liquids are less dense than solids. Because nonmetals contain about equal numbers of solid and gas or liquid elements, they have a greater density range than the predominantly solid metals.
Is petrol natural?
Yes it is. But anyhow some chemicals are added to it to make it change its properties.
Why do the properties of silver make it less useful in medicine?
as it is costlier . Less useful than what?
Which Properties make it difficult for electricity to pass through?
rubber would be an example of something that does not allow electricity to move through it easily
What are the different categories are the elements put into?
Metals, nonmetals, and metalloids which are elements that have some of the same properties as metals but not all properties to make them a metal
WHAT IS A CHANGE IN THE WATER QUALITY THAT MAKE IT UNSUITABLE FOR CERTAIN USE?
Water pollution can change the quality of water and make it unsuitable for drinking.
What is a metallloid?
A metalloid are the elements located on the "staircase" of the periodic table. They have properties of metals and nonmetals. They make for good semi-conductors. The most common is silicon, which is used in computers.
What 2 properties of copper make it desirable for use in wiring?
excellent conductor of electricityductile: can be drawn into thin wire without breaking
What category of elements would you choose to make container that wouldn't shatter if dropped during a test?
A metal will not shatter if dropped becuase a nonmetal can be anything, so, if you drop a metal, there is no possible way it can break.
What is the change in the quality of water that makes it unsuitable for certain uses?
Water pollution can change the quality of water and make it unsuitable for drinking.
What are the properties of matter ad explain each matter?
the properties of matter-is everything that has mass and space and anything in the universe. its properties are substance and mixtures substances are made up of elements and compounds the properties of elements are metals,nonmetals,and semi-metal metals are those things like wires,gears,spoons and many more. nonmetals are like wood,rock and others semi metals are aluminum and etc. In mixtures are homogeneous and heterogeneous. homogeneous means single and its properties is solutions. solutions is made up of solvent and solute solvent are used to dissolve solute. their are things that can make your solutions different its dependent and independent variables. heterogeneous has two properties its colliods and suspensions
Why does water makes it unsuitable for certain uses?
Turbulence, pollution, and organisms inhabiting it.
Why aren't you able to make jewelry's from non metals?
You can make jewelry from nonmetals.
Why do people mix metals with nonmetals?
So that they can make ionic compounds.
What kind of bond would two nonmetals make?
covalent bond
Why are film badges unsuitable for detecting alpha particle radiation?
Alpha can not make it through the badge holder to the film. This reason makes the film badges unsuitable for detecting alpha particle radiation.
