(6 cards)
1
Q
what type of atoms bond ionically?
A
metal and non-metal/ cations and anions/ atoms that want to lose and atoms the want to gain electrons
2
Q
how are ionic bonds formed?
A
electrons are transferred from atoms that want to lose electrons to atoms that want to gain electrons
3
Q
what is the attracting force between atoms in an ionic bond?
A
the strong electrostatic attraction between oppositely charged ions
4
Q
what type of charges do ionic compounds have?
A
neutral
5
Q
how atoms structured in ionic compounds?
A
in a crystal lattice structure - an array of positive and negative ions and ninety degrees, perpendicular to each other
6
Q
what are polyatomic ions?
A
polyatomic ions are covalent substances (want to gain an electron) that bond with metals (want to lose an electron)
