What are 5 chemical physical properties?
Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion. Iron, for example, combines with oxygen in the presence of water to form rust; chromium does not oxidize (Figure 2).
What is a physical property of elements?
A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.
What is a chemical property of a table?
The change of one type of matter into another type (or the inability to change) is a chemical property. Examples of chemical properties include flammability, toxicity, acidity, and many other types of reactivity.
What determines the chemical properties of an element?
Elements are distinguished from one another by the numbers of these particles they have, and so each element has its own unique atomic number. The chemical properties of an element are determined by its number of electrons, but in a neutral atom , this is the same as the number of protons.
What factors determine element’s chemical properties?
The chemical properties of an element are determined by the configuration of its electrons in orbit around its nucleus. The number of electrons in orbit is equal to the number of protons in the nucleus (each proton has an an electrical charge of plus one, while each electron has the same charge only negative one).
What are 10 chemical properties?
Here are some examples of chemical properties : Reactivity with other chemicals Toxicity Coordination number Flammability Enthalpy of formation Heat of combustion Oxidation states Chemical stability Types of chemical bonds that will form More examples
What are the chemical properties of Group 7 elements?
Elements in group seven have a number of similar properties, most importantly they have low melting and boiling points. This is of course a typical property of non-metals. From the lowest boiling and melting point to the highest, the group in order is fluorine, chlorine, bromine, iodine and astatine.
