Lewis Dot Structures

CAVA chem 302 & 303 S1U4L13 Lewis Dot Structures

QuestionAnswer
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.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
