GFM + ions + moles Flashcards
1
Q
positive ions
A
+
formed when atoms lose electrons
1 positive charge for each electron lost
2
Q
negative ion
A
-
formed when atoms gain electrons
1 negative charge for each electron gained
3
Q
p.n.e in ions
A
the same as atoms but the electrons are affected by whether it’s a positive or negative ion
4
Q
electron arrangement in ions
A
the same as atoms except the missing/additional electrons affect the outer shell
5

7
Q
calculating mass with a number of moles
A
mass= mole number x GMF
