Chemical Bonding – Ionic and Covalent Compounds – Notes
Metals and Non-Metals
Metals are elements that have a tendency to lose electrons and form positively charged ions or cations.
Elements that have a tendency to accept electron to form negatively charged ions or anions are called non- metals.
Metals are placed on the extreme left in the periodic table, while non-metals are placed on the extreme right in the periodic table.
Metals are solids, malleable, ductile, and lustrous with high melting and boiling points.
Non-metals are electronegative, bad conductors of heat and electricity, from acidic oxides which are covalent.
Electrolysis is a process of decomposition of an ionic compound by passing electricity through it.
Carbon and its Compounds – Bonding in Carbon
Covalent compounds have low melting and boiling points.
