What is considered a chemical property?
A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.
Is odor a chemical property?
Characteristics such as melting point, boiling point, density, solubility, color, odor, etc. are physical properties. Properties that describe how a substance changes identity to produce a new substance are chemical properties. Physical and chemical properties can be used to classify a substance as ionic or molecular.
What are the chemical behavior of an element?
Its chemical behavior is determined by the atomic number 2 (the number of protons), which equals the normal number of electrons; the stability of its nucleus (that is, its radioactivity) varies with its atomic weight (approximately equal to the number of protons and neutrons).
What property of the element determines its chemical Behaviour?
The property of an element that determines its chemical behaviour is: (b) valency of an element. – Actually, the chemical behaviour of an element is determined by its electronic configuration.
What is considered chemical?
A chemical by definition is any substance consisting of matter; this includes solids, liquids, and gas. Chemicals can either be of a pure substance or a mixture of substances. A chemical substance such as water (H2O) is a pure chemical because it has the same molecules and combination throughout its structure.
What makes a property a physical or chemical property?
Identify properties of and changes in matter as physical or chemical The characteristics that enable us to distinguish one substance from another are called properties. A physical property is a characteristic of matter that is not associated with a change in its chemical composition.
When do we see the properties of a substance?
Chemical properties are characteristics or properties of a substance that can be observed when undergoing chemical changes or reactions. The chemical properties are seen during or following the reaction because the arrangement of atoms in the sample must be disturbed for the property to be investigated.
When do the properties of a chemical change?
Chemical properties are properties a chemical exhibits when it undergoes a change. This change could be due to a chemical reaction to result in a change of the matter or compound. The questions below will provide additional practice and understanding of chemical properties.
How is chemical stability a property of matter?
This is a property of matter that is determined by its specific conditions, so it can’t be observed without exposing a sample to that situation. Thus, chemical stability fits the definition of a chemical property of matter.
