UNIT1-Ionic Bonding- forming ions Flashcards
1
Q
What kind of element looses electrons?
A
Metals always LOSE electrons to become positively charged ions called cations.
2
Q
What kind of elements gain electrons?
A
Non-metals always GAIN an electron to become negatively charged ions called anions.
3
Q

Q
What makes all atoms more stable?
A
All atoms are more stable when they have a full outer shell of electrons like the Noble gases.
5
Q
how are ions formed?
A
Other elements have to lose or gain electrons to become more stable.
They become charged particles called ions.
