what is ionic bonding ? -
its when atoms gain or loose electrons to form charged particles called ions which are then strongly attracted to one another.
1 of 13
whats it called when an atom loses electrons ? -
oxidation.
2 of 13
whats it called when an atom gains electrons ? -
reduction.
3 of 13
in an atomic structure how many electrons can the first shell hold ? -
it can hold a maximum of two electrons.
4 of 13
in an atomic structure how many electrons can the other outter shells ? -
it can hold a maximum of eight electrons.
5 of 13
what is found in the nucleus in an atom ? -
protons and neutrons.
6 of 13
explain the atomic structure -
in the middle theres a nucleus, then an inner shell then outter shells if needed to hold the elctrons on.

what is an ion ? -
an ion is a charged atom or a group of atoms.
8 of 13
how is a negative ion formed ? -
when an atom/group of atoms gains one or more electrons.
9 of 13
what is ment by a lattice structure ? -
a small compact structure where ions form by being compelled by opposite charged atoms.
