Everything around us is made up of atoms. The atom is more than a million times smaller than the thickness of a human hair. The smallest speck that can be seen under an ordinary microscope contains more than 10 billion atoms. Even though atoms are incredibly tiny, they are made up of even more minute particles: protons, neutrons, and electrons.
Atoms, molecules and elements are the building blocks of everything we can see, hear, and touch. Though not visible to the naked eye, it is the combination of millions of these tiny substances that make us who and what we are today. Many elements make up the world around us, and each element reacts differently to its surroundings.

The purpose of an essay is to develop and present your own thinking about the texts and issues raised by the question. All essays are likely to draw on ideas taken from others, whether from critical books, lectures or discussions.

Question. State the number and type of atoms in one molecule of chlorine, Cl 2. Reveal answer. A chlorine molecule is made up of two chlorine atoms. An explanation of covalent bonding.
All elements are made of atoms which combined with each other form new atoms. They come together in large or small numbers to form very similar or very different atoms and as a result of the combination it is known as a chemical bond. Atoms linked together by bonds have different properties to the original parent atoms.
Chemical compounds can generally be classified into two broad groups: molecular compounds and ionic compounds. Molecular compounds involve atoms joined by covalent bonds and can be represented by a variety of formulas. Ionic compounds are composed of ions joined by ionic bonding, and their formulas are generally writtenusing oxidation states.
