What Is Molecule Short Answer

What is 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 in chemistry definition?

molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance. representations of molecular structure.

What is molecule for 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 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 molecules for Class 11?

What is a Molecule? (Molecule Definition) 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.

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.

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.

What is molecule and its types?

(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 is the largest molecule?

The largest molecule is called PG5. This molecule is the size of a normal virus. PG5 has a length of 10 nanometers in a diameter and weighs an estimate of 200 million hydrogen atoms. This molecule is synthetic-made, meaning that the molecule is made in laboratories.

What is the molecular class 9?

Molecules are formed when one or multiple atoms combine by chemical bonds. It is the smallest constituent of an element that exhibits its properties. Molecules can be formed by two or more atoms in a chemical bonding. This section explains the atoms and molecules class 9 science notes in detail.

What is difference between atom and molecule?

Atom is the smallest particle of any element, whereas a molecule is the smallest particle of the compound. 2. Atoms may or may not present independently whereas molecules exist independently.

Is water a molecule?

Atoms join together to form molecules. A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That’s why water is sometimes referred to as H2O. A single drop of water contains billions of water molecules.

What is molecule class 2?

(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.

What is molecule in biology?

A molecule is the smallest unit of matter that has distinctive chemical and physical properties. A molecule owns a definite size and mass. Two or more atoms (same or different) held together by a chemical bond form a molecule wherein the ratio of two atoms is fixed in an element.

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 5th grade definition?

Molecule: A particle made up of a group of atoms that are chemically bonded. A molecule of water contains two hydrogen atoms and one oxygen atom.
