Question

what are atoms and molecule explain with example ​

Answer 1

Answer:

The universe is made up of atoms, which contain protons (positively charged particles), neutrons (particles with no charge), and electrons (negatively charged particles).

 Molecules are formed when two or more atoms bond together. If molecules contain atoms of different elements, that substance is known as a compound.

Hydrogen (H2), oxygen (O2), and chlorine (Cl2) molecules, for example, each contains two atoms. Another form of oxygen, ozone (O3), has three atoms, and sulfur (S8) has eight atoms. All elemental molecules are made of atoms of a single element.

Answer 2

Answer:

Atom

     Atoms are defined as “the basic building blocks of matter”.

• It is the smallest constituent unit of matter that posses the properties of the chemical element.
• Atoms don’t exist independently, instead, they form ions and molecules which further combine in large numbers to form matter that we see, feel and touch.
• A typical atom consists of a nucleus of positively-charged protons and electrically neutral neutrons with negatively-charged electrons orbiting this nucleus .
• Ex Hydrogen ( H ) , Oxygen ( O ) , etc.

Molecule

     A molecule is defined as the smallest unit of a compound that contains the chemical properties of the compound.

• Molecules consist of one or more atoms bound together by covalent (chemical) bonds .
• 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).
