Atoms in Ions Flashcards
what particles are involved in ionic and covalent bonding?
ionic = metal and non-metal covalent = non-metal and non-metal
describe how a group 1 ipn becomes positive (with an example)
a group 1 metal becomes a positive ion because it loses a negatively charged electron so then there are more positive protons than negative electrons therefore the ion becomes positively charged overall (example is sodium)
describe how ionic bonding happens between group 1 and group 7 compounds in terms of electron transfer.
group 1 and group 7 want to have full outer shells. group 1 has one electron in its outer shell so it wants to lose it to get a full outer shell (8 in a full outer shell except for the first one with 2 in it) and group 7 needs 1 electron to complete it’s outer shell therefore group 1 gives its on away and group 7 takes it so they can both have full outer shells.
how can you describe the charge of an unfamiliar ion depending on its position in the periodic table?
groups 1-3 will be positive because they lose negative electrons so there are more positive protons than negative electrons (positive overall) and groups 5-8 will be negative because they are gaining negative electrons so there will be more negative electrons than positive (negative overall)
give an example of a group 7 element that becomes negative
