What is an molecule in chemistry?
A molecule is two or more atoms connected by chemical bonds, which form the smallest unit of a substance that retains the composition and properties of that substance.
What is a molecule short answer?
A group of two or more than two atoms of the same or different elements that are chemically bonded together is called a molecule. For example, two atoms of hydrogen and one atom of oxygen react with each other and form one molecule of water.
What is a molecule science definition example?
A molecule may consist of two or more atoms of a single element or atoms of different elements. Here are some examples of molecules: H2O (water) N2 (nitrogen)
What is called atom and molecule?
A group of two or more atoms is linked together by sharing electrons in a chemical bond. A molecule is a collection of two or more atoms that are securely bound together by attractive forces or by chemical bonds. The term “atom” refers to the tiniest unit of matter that can be separated.
What is molecule and type in chemistry?
(1) A molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound. Molecules are made up of atoms that are held together by chemicals bonds. (2) There are two types off molecules : 1. Molecules of an element : Molecule of an element is made up.
What are 3 types of molecules?
Molecules are of three types: Molecule of an atom, Molecule of an element and Molecule of a compound.
What is a molecule Class 9 example?
A group of atoms that combine together and form a single entity. Ex- H 2 O where 2 atom of H and 1 of oxygen forms a molecule of water.
What is difference between molecule and compound?
A molecule is a group of two or more atoms held together by chemical bonds. A compound is a substance which is formed by two or more different types of elements which are united chemically in a fixed proportion. All molecules are not compounds. All compounds are molecules.
Why is it a molecule?
Whether something is a molecule or not depends on the type of bond that is formed when its atoms join together. In general, electrons can be shared between atoms (a molecular bond) or electrons can be completely removed from one atom and given to another (an ionic bond). Molecules have molecular bonds.
What is a molecule student definition?
A molecule is the smallest unit of a substance that has all the properties of that substance. For instance, a. water molecule is the smallest unit that is still water. A water molecule can be divided into tiny parts called atoms. This produces two hydrogen atoms and one oxygen atom.
What is molecule Class 11 example?
Molecule is defined as the combination of one or more atoms that are combined with the help of chemical bonds. These bonds can be covalent, ionic, metallic or co-ordinate bonds. For example water, it is a molecule which is formed of two hydrogen atoms and one oxygen atom.
What is a molecule for kids?
A molecule is two or more atoms joined (or “bonded”) tightly together. The number and kinds of atoms in a molecule, and the way they are arranged, determine what substance it makes. For example, a molecule made of two oxygen atoms joined to one carbon atom forms carbon dioxide, a colorless gas.
