What is a solution Class 9?
A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm.
Common examples of solutions are the sugar in water and salt in water solutions, soda water, etc.
There is particle homogeneity i.e.
particles are evenly distributed..
What is an element Class 9?
Element: An element is a substance which cannot be split up into two or more simpler substances by the usual chemical methods of applying of heat, light or electric energy. Compound: A compound is a substance made up of two or more elements chemically combined in a fixed proportion by mass.
What is classification of elements?
Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals.
How many classes of elements are there?
three different classesAnswer and Explanation: Elements on the periodic table are divided into three different classes: metals, non-metals, and metalloids.
What is an element Grade 9?
Elements. A pure substance that cannot be. broken down or separated into. simpler substances. Made up of one kind of atom.
What are the two types of elements?
Elements are typically classified as either a metal or nonmetal, but the dividing line between the two is fuzzy. Metal elements are usually good conductors of electricity and heat. The subgroups within the metals are based on the similar characteristics and chemical properties of these collections.
What are the 4 types of elements?
There are four main groups of elements in the periodic table: main group metals, non-metals, metalloids, and transition metals (See types of elements).
What is the name of elements in group 2?
Group 2A — The Alkaline Earth Metals. Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They are harder and less reactive than the alkali metals of Group 1A.
What are the 3 major categories of elements?
The three major groups on the Periodic Table are the metals, nonmetals and metalloids. Elements within each group have similar physical and chemical properties.
What are the three main types of elements Class 9?
Types of Elements The elements are arranged in the periodic table and are split depending upon their groups as either metallic or non-metallic. Metallic is further classified into Main Group Metals, Transition Metals, and f-block metals. These are again further divided, depending upon their properties.
