Question | Answer |
---|---|
Covalent bonds form between atoms that share pairs of [...] electrons. | Covalent bonds form between atoms that share pairs of valence electrons. |
Only the [...] electrons are important in bonding. | Only the valence electrons are important in bonding. |
Gilbert [...] found a simple way to represent chemical bonding. | Gilbert Lewis found a simple way to represent chemical bonding. |
Lewis used [...] to represent the valence electrons of an atom. | Lewis used dots to represent the valence electrons of an atom. |
structures drawn using Lewis's method are called [...] structures | structures drawn using Lewis's method are called Lewis dot structures. (or just Lewis structures) |
A Lewis structure's basic notation includes the [...] of the element, surrounded by dots that represent its valence electrons. | A Lewis structure's basic notation includes the symbol of the element, surrounded by dots that represent its valence electrons. |
Lewis Dot Structures: When placing dots around a symbol, place one dot on all four sides (top, bottom, right, left) and if you have more left over, start [...]. | Lewis Dot Structures: When placing dots around a symbol, place one dot on all four sides (top, bottom, right, left) and if you have more left over, start doubling up. |
In the old A/B periodic table, the number of each group tells you the number of [...] for all atoms in that group. | In the old A/B periodic table, the number of each group tells you the number of valence electrons for all atoms in that group. |
Octet Rule: 8 is the stable number of electrons (but 2 is for small atoms). | Octet Rule: 8 is the stable number of electrons (but 2 is for small atoms). |
The central atom in a molecule is never [...]. | The central atom in a molecule is never Hydrogen. |
The central atom in a molecule is usually the one that wants to [...]. | The central atom in a molecule is usually the one that wants to form the most bonds. |
Lewis Dot Structures: you need to find the total number of [...] in the molecule. | Lewis Dot Structures: you need to find the total number of valence electrons in the molecule. |
Lewis Dot Structures: At first, connect atoms with a [...] of electrons. | Lewis Dot Structures: At first, connect atoms with a pair of electrons. |
Lewis Dot Structures: After forming single bonds with pairs of elecrons, distribute the remaining valence electrons; trying to give each atom a full '[...]'. | Lewis Dot Structures: After forming single bonds with pairs of elecrons, distribute the remaining valence electrons; trying to give each atom a full 'octet'. |
Lewis Dot Structures: If you don't have enough electrons to give each atom a full octet, try creating [...] bonds, or [...] bonds. | Lewis Dot Structures: If you don't have enough electrons to give each atom a full octet, try creating double bonds, or triple bonds. |
