2. What is a compound? A. Many atoms bonded together B. What makes up ...
Atom
atoms-imgAll the matter in the universe is made of tiny particles called atoms.  There are 92 different kinds of atoms in nature. These 92 different atoms combine with one another to form different kinds of matter that we see in nature.
Gold, for example, is made of only gold atoms. When matter is made of only one kind of atom, it is called an element. In the same way, silver is another element which is made of only silver atoms. Because there are 92 different kinds of atoms in nature, there are 92 different kinds of elements. Other examples of an atom are K (potassium) and Fe (iron).
Elements
The element is the fundamental substance that consists of only one type of atom. Elements consist of smaller particles and can be man-made or synthetic. Their arrangement in the periodic table is based on the number of protons in an increasing order. The atomic number of an element is indicated by Z. When atoms are arranged differently in an element having the same number of protons, you get different forms of an element. For example, both graphite and diamond are elements of carbon but they look very different from each other.

Molecule:
molecule-imgA molecule is the smallest unit of a chemical compound and it exhibits the same chemical properties of that specific compound. As molecules are made up of atoms jointly held by chemical bonds, they can vary greatly in terms of complexity and size. The oxygen we breathe has a molecular formula O2. Should we consider this as an element or compound? When two or more atoms of the same elements combine together, we call them Molecules. So, we call O2 as an oxygen molecule. In the same way, we find hydrogen molecules H2, chlorine molecules Cl2 and others in nature.

Compound:
compounds-imgThe chemical formula of water is H2O. Observe that, water is made of two hydrogen atoms and one oxygen atom. Here, two different elements, hydrogen and oxygen combine, giving rise to a new substance called water. Such substances, which are made by the combination of two or more kinds of elements are called Compounds. The atoms in a compound are chemically bonded and hence cannot be separated easily. Similarly, the chemical formula of carbon dioxide is CO2 and it is made up of two elements, carbon, and oxygen. Some other examples of compounds are table salt (NaCl), chalk (CaCO3)and water (H2O).

Mixture:
mixture-imgThe mixture is a substance made by the physical combination of two or more different elements or compounds. A mixture does not involve any chemical reaction. So, if you mix the magnetized powder with sand, you get a mixture that can be separated physically by means of a magnet. It can be composed of solids, liquids or gases and can be classified into 6 different categories – homogenous, heterogeneous, solutions, alloys, suspensions, and colloids.

Direction: Read the passage and answer the questions given, one mark questions.Anything that occupies some space, having mass, volume and can be felt by one or more out of five senses is called matter. The purest form of matter is called an element. An element is a substance which cannot be split up into two or more simpler substances by the usual chemical methods of applying heat, light or electric energy.A pure substance consists of a single type of particles. All the elements and compounds are pure substances because they contain only one kind of particles. eg. Hydrogen, Carbon, Oxygen, Carbon-monoxide, Copper, Gold, Silver. A pure substance has a fixed composition as well as a fixed boiling point and melting point. The presence of impurities generally increases the melting and boiling point of the pure substancesQ. The boiling point of pure water is 100oC. What likely be the effect on the boiling point of water if 150 gm NaCl is added to one litre water.
