What properties of metals and saltwater make them good materials for a battery?
saltwater contains ions that help in the flow of electricity as they can 'carry' positive or negative charges.
What are the 3 main groups of metal?
54 of our chemical elements are classed as metals. All metals share certain properties such as being ductile (capable of being deformed or stretched), malleable (easily bent or shaped) and a conductor of heat and electricity. The metals are divided into different groups depending on their other properties. An element's properties are a result of how many electrons are in its outer energy level and position on the periodic table is based on this. This means each group of elements that share similar properties occupies a specific area on the periodic table. The metal groups are alkali metals, alkaline earth metals, transition metals and other metals. The alkali metals and the alkaline earth metals, groups one and two respectively on the periodic table, have similar properties. Due to their high reactivity they are not found in their pure forms naturally. The elements that make up the alkali metals are lithium, sodium, potassium, rubidium, caesium and francium. They all have only one electron in the outer energy level, meaning they behave similarly in the formation of compounds. Alkali metals react violently with water. For instance, if potassium is dropped in water it floats around while emitting a violet flame. Groups one metals are relatively soft, with low densities and melting points compared to other metals. The alkaline earth metals form group two of the periodic table, so each have two electrons in their outer shell. These are beryllium, magnesium, calcium, strontium, barium and radium. They have similar properties to the Alkali metals in group one. Group two metals, when compared to group one metals on the same period (row) of the periodic table, show some consistent differences. The group two metals are less reactive than those in group one. For instance calcium can react only with hot water, whereas potassium, its group one counterpart, reacts violently with any water. The group two metals have higher melting and boiling points and are harder, stronger and denser. The transition metals lie in the centre block of the periodic table, in groups 3 to 12. There are 38 transition metals, including elements such as iron, gold and zinc. Transition metals share some common characteristics. The majority are a silvery-blue colour at room temperature (copper and gold being the exceptions to this.) Many form coloured compounds, and many are good catalysts. They have high densities and melting points. The three magnetic elements iron, cobalt and nickel are all transition metals. The final group is the "other metals", or "poor metals" located in groups 13, 14 and 15. This includes aluminium, gallium, indium, tin, thallium, lead and bismuth. They are softer than transition metals, with lower melting and boiling points.
What metals are used to make ferromagnets?
iron, nickel and cobalt
Which metals would make the best electromagnet core?
iron
How did Albert Einstein make the atom?
Albert Einstein, never made the Atom. Einstein main claim to fame is with his Theory of Relativity. John Dalton was one of the earliest men to Discover the properties of the atom
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
Which properties of metals do you utilise to make a copper wire?
Ductility is the property of metals that enables them to be drawn into wires......
What two properties of metals make them good for bicycle frames?
It is light and strong
What are the properties of metals that make it useful for electricians?
Plastic is a property of metal for electricians
Oxides react with oxygen and water and are used to make paints are some of the properties of which type of metals?
alkaline earth metals
The two properties of metals that pertain to their ability to be drawn into wires are pounded into shape are?
Ductality and malleablity are the two qualities of metals which would make metals' ability to be seperated into wires and sheets respectively.
What are four properties of metals and what does each mean?
Four properties of metals are: hardness (resistance to erosion), ductility (possibility to make wires), maleability (possibilty to be easy machined), melting point (temperature for the change solid to liquid), etc.
What properties of metal make them good for jewelry?
Metals do not react with substances in our skin. Also, they are malleable, which allows for us to shape them to make jewelry.
What characteristic of a metal allows it to conduct electricity?
The physical properties of different metals make them useful for different purposes in metals can move through the metal, allowing metals to conduct electricity.
What are the properties of the alkaline earth metals?
They are shiny, silver, less malleable than alkali metals and they burn with bright flames. They also make strong bases (Opposite of acid).
Blew main fuse replaced it.. car still wont start?
If replacing the main fuse does not make the repair, it is likely another fuse is also blown. Sometimes fuses will blow all along a circuit.
When an engineer is making a mixture of metals to make steel for the frame of a building what two properties should the steel have?
strong and slightly flexible
