Ionic and Covalent Bonds
Learning Logs
This week in Chemistry, the main focus of the week was Chapter 6, Ionic and Covalent Bonds. A chemical bond is an electrical attraction between nuclei and valence electrons of different atoms that binds them together. An Ionic bond (type of chemical bond) are bonds between metals and non-metals, in general. Electrons from left and right of the periodic table, a transfer of electrons. A covalent bond are bonds between two non-metals, both from right of the periodic table. This results from the sharing of electrons. Metallic bonds are bonds between two non-metals. Both from the left of the periodic table, electrons move freely. A bond is Ionic if the electronegativity is over 1.7. When a bond is covalent, the electronegativity is over 1.7 and a maximum of 3.3. Non-polar is when some strength shares electrons equally, some examples are carbon and hydrocarbons. Polar is when one atom is stronger and electrons are unequally shared, example is H20. An ionic bond is potassium (K) and bromine (Br), and carbon (C) and oxygen (O) is a covalent bond. A molecule is a neutral group of atoms held together by covalent bonds. A molecular compound is a chemical compound whose simplest unit are molecules. The chemical formula indicates the number of atoms of each kind in a compound, can be ionic or covalent. Bond length is the average distance between two bonded atoms, and bond energy is the energy required to break a chemical bond. The Octet rule is when atoms form bonds to obtain 8 valence electrons. A diatomic molecule is a molecule with only two atoms. The molecular shape is determined by the number of bonded sets, single, double or triple bonds, and lone pairs electrons around the central atoms. The polarity is determined by how electrons are shaped in a molecule.
