An Ionic bond happens when an atom loses or gaions one or more electrons from its outer shell
Example!!!
Nomenclature Steps: 1. Identify the compound as ionic 2. Identify the elements in the compound 3. Write the full name of the cation first 4.Write the base name of the anion and add -Ide to complete the name
Polyatomic Example: Na(NO2) 1. Na- metal NO2- non metal 2. Ionic 3. Sodium 4. Nitrite 5. Sodium Nitrite
Example KCl: 1. K-metal Cl- nonmetal 2. ionic 3. Potassium 4. Chloride 5. Potassium Chloride
Example Cr+3 Br-1: 1. Cr+3 Br-1 2. Cr1 Br3 3. Cat 1(+3charge)=+3 Anion 3(-1charge)=-3 4. CrBr3
Covalent bonding is the combination of two or more atoms by sharing electrons so as to achieve chemical stability under the octet rule.
1. Identify the names and total number of each element in the compound 2. Identify the compound as covalent 3. Write the full name of the first non-metal with the corresponding prefix if there is more than one 4. Write the base name of the seoond non-metal +ide with the correct prefix indicating how many atoms are in that compound
Example!!
Example!!!!
VSEPR stands for Valence Shell Electron Pair Repulsion theory
VSEPR is a model in chemistry used to predict the shape of individual molecules based upon the extent of electron-pair electrostatic repulsion
