Chemical bonding

• A unique group of elements that share the same properties of both metal and non metal
• Metalloid - A unique group of elements that share the same properties as both metal and non metal
• Compound - are chemical substance made up of two or more elements that are chemically bound together
• Chemical Bonding - a lasting attraction between atoms, ions or molecule that enables the formation of chemical compounds
• Types of chemical bonding - Ionic bonding and covalent bonding
• Why do atoms bond? To become stable
• Ionic bonding - is formed through complete transfer of electron from one ion to another.
• Ionic bonding - it exists between metals and nonmetals
• Ions - is an atom or molecule with positive or negative charge
• There are 8 groups in the periodic table
• cation - loss of electron
• anion - gain of electron
• Covalent bonding also called as molecular bond, it is a chemical bond that involves sharing of electron pairs between atoms
• Covalent bonding - bonding of 2 nonmetals
• Nonmetals - have strong energy attractions or high electronegativity compared to metals
• 2 types of ovalent bond - Non polar covalent bond and polar covalent bond
• Non polar covalent bond - equal sharing of electrons
• Polar covalent bond - unequal sharing of electrons
• Ionic Bonding - bonding of metal with non-metal
• Electronegativity is the ability of the atom to attract electron
• Ions are simply charged atoms. They are neither positive nor negative
• Ions are formed as atoms to gain or lose electrons
• Metals tend to. lose electrons
• nonmetals tend to gain electrons caus ethey have higher electronegativity
• the higher the electronegativity The higher it is to attract or gain electrons
