1 \u2013 An atom is the smallest particle of an element still having the same chemical properties of the element.<\/p>\n\n\n\n
2 \u2013 Atoms are the basic building blocks of matter that make up everyday objects. A desk , the air , even you are made up of atoms!<\/p>\n\n\n\n
3 \u2013 Everything in the universe consists of atoms.<\/p>\n\n\n\n
4 \u2013 They are the basis for everything in the Universe.<\/p>\n\n\n\n
5 \u2013 If you want to create a language , you\u2019ll need an alphabet. If you want to build molecules , you will need atoms of different elements.<\/p>\n\n\n\n
6 \u2013 An atom is like a solar system in miniature. It has a central \u2018sun\u2019 or nucleus which has a number of \u2018planets\u2019 or electrons \u2018orbiting\u2019 around it.<\/p>\n\n\n\n
7 \u2013 If you make a tiny dot with the tip of a sharp pencil , and if the pencil lead was all carbon atoms , that little dot would have about four billion carbon atoms in it.<\/p>\n\n\n\n
8 \u2013 The average atom is about one tenth of a billionth of a meter across. Atoms are really small!<\/p>\n\n\n\n
9 \u2013 An atom contains protons , neutrons , and electrons.<\/p>\n\n\n\n
10 \u2013 Protons have a positive electrical charge and are found together with neutrons (no electrical charge) in the nucleus of each atom.<\/p>\n\n\n\n
11 \u2013 Negatively charged electrons orbit the nucleus , much like a satellite attracted to the gravity of the Earth.<\/p>\n\n\n\n
13 \u2013 Even though protons and neutrons make up the nucleus of an atom , most of the nucleus is empty space.<\/p>\n\n\n\n
14 \u2013 Atoms are made up mostly of \u201cempty space \u201c.<\/p>\n\n\n\n
15 \u2013 A hydrogen atom is about 99.9999999999996% empty space.<\/p>\n\n\n\n
16 \u2013 Have you ever think the miracle in the formation of the atoms? How come by adding one proton and one neutron in the nucleus and adding one electron in it\u2019s orbit each time , different atoms are formed! And different atoms with different properties and funtions. And although the functions are different but are important and useful to humanity.<\/p>\n\n\n\n
