Chem Test Wednesday- what is the charge when the atoms acquire a complete set of valence electrons?
How do i find, in simple terms from the periodic table what the charge will be when the following atoms acquire a complete set of electrons. Oxygen, NA, F< or N for instance!
In response to your responce, im not sure how to get the charges or the # of valence electrons its supposed to start with!
Well, you’ll have to look at it’s original state. Like oxygen. Oxygen normally has 6 valence electrons, so to get a full shell (8), it’ll need two more. The charge of the oxide anion is -2.
Sodium has 1 VE. So, the best way for it to get a full shell is to drop that lone e. Hence the +1 charge.
F has 7, so it has to pick up one, forming F- with a -1 charge.
N has 5 e’s normally, so it picks up three to get a -3 charge.
