2
Q
cations?
A
positively charged ions formed when one or more electrons are lost from an atom
3
Q
what do the number of electrons lost or gained determine?
A
the number on the charge
4
Q
anions?
A
negatively charged ions formed when an atom gains one or more electrons
5
Q
forces of attraction between oppositely charged ions
A
strong electrostatic forces
6
Q
how is an ionic compound formed?
A
metals transfer their outer shell electrons to non metals to form an ionic compound
7
Q
when is an atom more stable?
A
when it has a full outer shell
8
Q
what has the same electronic structure as an ion and what does this mean?
A
noble gases, they have a full outer shell
