What are the 3 physical properties?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.
What is an element with example?
Elements are the tiny particles that make up matter. Science describes an element as a pure substance made of only 1 type of atom that can not be broken down further into other substances. For example, hydrogen (H) and oxygen (O) are elements, but water (H2O) H 2 O ) which is made of hydrogen and oxygen is NOT.
What are the 5 types of elements?
The basic elements are wood, fire, earth, metal, and water.
What are the properties of group One elements?
Group one elements share common characteristics. They are all soft, silver metals. Due to their low ionization energy, these metals have low melting points and are highly reactive. The reactivity of this family increases as you move down the table.
What are the examples of alkali?
Alkalis. Alkalis are bases that dissolve in water. Common alkali-containing substances are lyes, ammonia, hair-relaxing agents, nonphosphate detergents, dishwasher soaps, and disk batteries. Lyes are alkaline agents that contain sodium hydroxide (NaOH), potassium hydroxide (KOH), or calcium hydroxide (Ca(OH)2).
What is an example of two elements?
Carbon dioxide, nitrous oxide, and methane are all compounds that consist of two elements.
Which of the following is a property of an elements?
The properties of elements are: Element is made up of one kind of atom. Elements combine to form compounds. They cannot be broken down into two or more simple substances by physical means or by chemical means.
What are examples of properties?
Examples of property, which may be tangible or intangible, include automotive vehicles, industrial equipment, furniture, and real estate—the last of which is often referred to as "real property." Most properties hold current or potential monetary value and are therefore considered to be assets.
What are the 4 types of elements?
- The elements are classified as metal, non-metal, and metalloid.
- The extreme left side elements in the periodic table are metals, for example, sodium, calcium, caesium, etc.
- However, elements on the right side are generally referred to as non-metals, carbon, chlorine, oxygen, etc.
What are the properties of Group 7 elements?
Properties of Group 7 Elements
- At room temperature (20 °C), the physical state of the halogens changes as you go down the group. Fluorine and chlorine are gases, bromine is a liquid and iodine is crumbly solid.
- The colours of the halogens also change as you descend the group – they become darker.

What is example of base?
Examples of bases are sodium hydroxide, calcium carbonate and potassium oxide. A base is a substance that can neutralize the acid by reacting with hydrogen ions. Most bases are minerals that react with acids to form water and salts. Bases include the oxides, hydroxides and carbonates of metals.
