Covalent Bond Video. A covalent bond is the chemical bond formed between two atoms when they share electrons in pairs. When atoms come near each other, their electrons are attracted towards the nucleus of the other atom. If the outside shell is not filled, this attraction becomes stonger.

A covalent bond is the chemical bond formed between two atoms when they share electrons in pairs. When atoms come near each other, their electrons are attracted towards the nucleus of the other atom. If the outside shell is not filled, this attraction becomes stonger. The electrons are now being shared by both atoms, and they both have a full outer shell.
Covalent bonds - a bond formed when atoms share electrons to obtain full outer energy levels energy levels are at least half full of ve- all non metals
Solutions do not conduct electricity Low melting points - less than 300 Low boiling points Some have a strong odor Weak Bonds

Use the highlighter to select the compounds that are covalently bonded. Use the highlighter to select the compounds that are covalently bonded. H2O HCl NaF CO2 LiO MgO NaCl CH4 NH3
E-Dot Diagrams Examples: H Cl Br Br
Double covalent bonds - share two pairs of electrons
Triple covalent bonds - share three pairs of electrons Triple bonds are harder to break than double bonds - takes more energy. Double and triple bonds are shorter than single bonds
Binary Covalent Compounds end in ide. BF3 When there is only one first element ,do not use Mono prefix Boron trifluoride N-nitr ide P-phosphide S-sulfide Cl-Chloride F-fluoride O-oxide I-iodide Br-bromide 4.3.6
Polar Covalent Bonds - electrons are attracted to the nucleus of one atom more than another Example: H20
Nonpolar Covalent Bond - electrons are shared equally between the nucleus of atoms as they have equal attraction Example: H2
