Why atoms bond? 00:07 • Bond means chemical link which is responsible for holding atoms together. Atoms form chemical bond to have full outer shell of electrons. This makes the atom to become stable. • 2. Ionic Bond 01:10 • In ionic bonding, metal atom lose electron and non-metal atom gains electron. This transfer of electrons make the metal atom to become into a positively charged ion and the non-metal atom to become into a negatively charged ion. The positive and the negative ions have attraction ( electrostatic attraction) and this attraction is the ionic bonding. Ionic bonding happens between metal and non-metal, e.g. NaCl (Sodium Chloride). Ionic substance can form into a large structure called giant ionic structure. • 3. Covalent Bond 02:13 • In covalent bonding, the electrons are shared between the atoms. If there are one pair of electrons which is a total of two electrons in the overlap then such bonding is a single bond and has only one line. If there are two pairs of electrons which means a total of four electrons in the overlap then it is a double bond and it has two lines. Covalent bonding happens between non-metals and non-metals, for example water molecules which is H2O. Hydrogen is a non-metal and oxygen is a non-metal. Covalent substances can form into 3 types of structures which are simple molecular substances, giant covalent structures and nanoparticles. • MUSICS: • Son of a Rocket Kevin MacLeod (incompetech.com) • Licensed under Creative Commons: By Attribution 3.0 • http://creativecommons.org/licenses/b... • Cut and Run Kevin MacLeod (incompetech.com) • Licensed under Creative Commons: By Attribution 3.0 • http://creativecommons.org/licenses/b...
