Electronic Structure
- The electronic structure of an atom
is a description of how the electrons
are arranged.
- It can be shown as number of
diagrams. (Preferably, diagrams)
- The smallest amount of electrons (the dots or
crosses on the circle) you can have in a shell
(the circle) is 2 on the very first shell (which is
the smallest one)
- When you have 8 electrons
(dots or crosses) on the
second shell (the circle
around the smallest one),
you need to start the third
shell. (a circle going around
the other circle.
- The number of shells surrounding the
atom determine how reactive the atom is.
- If there are 5 shells then it is really
reactive but if there is one shell then it
isn't really reactive or might not be
reactive at all.
- If there are 5 shells then it is really
reactive but if there is one shell then it
isn't really reactive or might not be
reactive at all.
- If an atom GAINS electrons then it is a
negatively charged ion and if it
LOOSES an electron then it is
positively charged.
- Remember the opposites.
- If you GAIN 2, then you must put brackets
around the ion and put 2-
- Remember the opposites.
