Is a metal that contains other elements to give it specific properties?
A metal that contains other elements to give it specific properties is called an Alloy. Many metals can contain other elements to give the metal specific properties. Steel is an alloy of Iron and carbon. Stainless steels contain various other alloying elements such as Chromium and Nickel.
How does combining elements into a compound affect their properties?
They will either bind on a mollecular scale to form "solutions", or on a non-mollecular scale to form "mechanical mixtures". Certain properties will cause the mixture to combust, give off gasses, or other things, depending on the elements and the ratios.
What are the general properties of matter.Describe each and give an example?
solid,liquid and gasses
What do you call metals that contain other elements mixed with them?
A metal that contains other elements to give it specific properties is called an Alloy. Many metals can contain other elements to give the metal specific properties. Steel is an alloy of Iron and carbon. Stainless steels contain various other alloying elements such as Chromium and Nickel.
What is the basis in which the present day periodic table is organized?
The Periodic Table is organized by atomic number, metals, nonmetals, metalloids, periods, groups, and stability.
What is glass composed of?
Glass is made out of sand which contains Silica. Often other elements are added to give the glass specific properties such as hardness.
Give the theory of mendleaf periodic table?
He said that If you arrange the elements accoring to their atomic numbers ,Then you will find that every 8th element has similar properties.
How do physical properties differ as you move across a period or down a group?
Moving down a group, the elements will have the same number if valence electrons. Tis will give them similar properties, such as the Noble Gases, or the extreme reactivity of Group I metals. Moving across a period, elements will begin to resemble each other less and share fewer properties the further apart they are in the row.
Propertes of matrices?
Algebraic Properties of Matrix Operations. In this page, we give some general results about the three operations: addition, multiplication.
What are the advantages of Mendeleev periodic table?
- predicted the discovery of undiscovered elements and also predicted their properties. - highlighted some atomic weights of elements were incorrect - showed regular gradartion in physical and chemical properties of elements. - provided for variance from atomic weight order - provided the basis for the modern periodic table
What are 7 elements igneous rock contains?
The seven main elements commonly found in igneous rocks are silicon, oxygen, aluminum, iron, calcium, sodium, and potassium. These elements make up the minerals that compose igneous rocks and give them their characteristic properties.
How does the modern periodic table arrange the elements?
In the modern version of the periodic table, the elements are arranged in increasing order of the atomic number. The chemical properties of an element can be predicted by its group. For example group 1 elements react violently to give away one electron to form +1 ions where group 18 elements are inert in standard temperature and pressure. This periodic table was introduced by Henry Mosley.
