Electron Dot Structures

Electron Dot Structures

based on valence electrons

shortcut to Bohr Model

write symbol for element

represent:

nucleus

protons

neutrons

inner / core electrons

draw dots around symbol

1st dot on top

2nd dot on right

3rd dot on bottom

4th dot on left

repeat pattern for 5th - 8th dot

examples:

Chemical Bond

holds 2 or more elements together

forms new compound

chemical reaction / chemical change

elements:

paired electrons

unpaired electrons

electrons want to be paired up

want to look like a Noble Gas

look for another element to bond with
