Quick Answer: What Does Molecule Mean In Science?

What are 3 examples of molecules?

Here are examples of common molecules:

  • H2O ( water )
  • N2 (nitrogen)
  • O3 (ozone)
  • CaO (calcium oxide)
  • C6H12O6 ( glucose, a type of sugar )
  • NaCl (table salt)

What is molecule Short answer?

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 chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms.

What is molecule explain with an example?

A molecule is a particle made up of two or more atoms that are chemically bonded together; the number of atomic nuclei making up a molecule is a determinate number. For example, HCl(g) is a molecule made of one hydrogen atom bonded to one chlorine atom.

What is a common example of a molecule?

In simple terms, a molecule is an atom that forms a chemical bond with another atom. This could be another atom of itself in the case of the oxygen gas humans breathe (O2), or it could be bonding with another atom as in when two hydrogen atoms chemically bond with oxygen to make water (H2O).

Is table salt a molecule?

Something like table salt (NaCl) is a compound because it is made from more than one kind of element (sodium and chlorine), but it is not a molecule because the bond that holds NaCl together is an ionic bond. This type of molecule is called a diatomic molecule, a molecule made from two atoms of the same type.

How do you identify a molecule?

Using the VSEPR theory, the electron bond pairs and lone pairs on the center atom will help us predict the shape of a molecule. The shape of a molecule is determined by the location of the nuclei and its electrons. The electrons and the nuclei settle into positions that minimize repulsion and maximize attraction.

How many atoms are in a molecule?

1 Answer. Molecule: group of two or more atoms held together by chemical bonds. So, minimum 2 atoms are required to form a molecule.

What is a molecule for kids?

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 called molecule?

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.

What is molecule and its types?

A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (H2O).

What is the best description of a molecule?

Answer: 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 chemical bonds.

What is the difference between an atom or molecule?

Atoms are single neutral particles. Molecules are neutral particles made of two or more atoms bonded together.

What is the most common molecule?

Nature, it turns out, has just the thing. While molecular hydrogen (H2) is the most abundant molecule in the universe, the next most abundant is the robust sounding ” protonated molecular hydrogen “, or H3+.

How molecule is formed?

A molecule exists when two or more atoms join together by forming chemical bonds. When atoms of at least two different elements come together to form chemical bonds, these molecules can be called compounds. Sodium chloride (NaCl) is a classic example of an ionic compound, or compound formed by ionic bonds.

What is a molecule class 9?

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 (H2) and one atom of oxygen (O2) react with each other and form one molecule of water.
