Instructions: 1. Choose a metal or a nonmetal atom. Include the symbol of your atom under the square brackets and identify (highlight or circle) whether it's a metal or nonmetal. 2. Draw a Bohr-Rutherford Diagram of your atom under the appropriate set of brackets. Find an element who can form an ionic bond by either gaining or losing your valence electrons. Draw the Bohr-rutherford Diagram of your second element's atom (in the other brackets). Include its symbol under the other pair of square brackets. 5. Add or erase valence electrons from the atoms to achieve an ionic bond. 6. Determine the charges of each ion in the bond (how many electrons were either gained or lost compared t the # of protons) and write this on the top right corner of the brackets. 7. Write the name of your ionic compound. 3. 4. Ionic Compound #1 [][] Symbol: Symbol: Metal or Nonmetal? Write the name of the ionic compound Metal or Nonmetal?
Formal Charges
Formal charges have an important role in organic chemistry since this concept helps us to know whether an atom in a molecule is neutral/bears a positive or negative charge. Even if some molecules are neutral, the atoms within that molecule need not be neutral atoms.
Polarity Of Water
In simple chemical terms, polarity refers to the separation of charges in a chemical species leading into formation of two polar ends which are positively charged end and negatively charged end. Polarity in any molecule occurs due to the differences in the electronegativities of the bonded atoms. Water, as we all know has two hydrogen atoms bonded to an oxygen atom. As oxygen is more electronegative than hydrogen thus, there exists polarity in the bonds which is why water is known as a polar solvent.
Valence Bond Theory Vbt
Valence bond theory (VBT) in simple terms explains how individual atomic orbitals with an unpaired electron each, come close to each other and overlap to form a molecular orbital giving a covalent bond. It gives a quantum mechanical approach to the formation of covalent bonds with the help of wavefunctions using attractive and repulsive energies when two atoms are brought from infinity to their internuclear distance.
