Bonding Flashcards
1
Q
What are covalent bonds
A
two atoms sharing one or more pairs of electrons
2
Q
what are ionic bonds
A
attraction between oppositely charged ions
3
Q
what are metallic bonds
A
attraction between positively charged ions and delocalised electrons
4
Q
when are positive ions formed
A
when an atom or molecule loses electrons the metals in group one and group 2 are most likely to lose electrons
5
Q
when are negative ions formed
A
when an atom or molecule gains electrons the nonmetals in group 7 are most likely to gain electrons
6
Q
what are ionic lattices
A
giant structures that are held together by strong electrostatic forces between oppositely charged ions
