Bonding Flashcards
1
Q
Molecular ion
A
A charged particle containing more than one atom
2
Q
Cation
A
Positively charged ion
3
Q
Anion
A
A negatively charged ion
4
Q
Ionic bonds
A
Very strong, take a lot of energy to break
Metal compounds nearly always have ionic bonds
5
Q
Covalent bond
A
A shared pair of electrons
6
Q
Lone pairs
A
Pairs of electrons that are not shared with another atom
7
Q
Covalent bonds
A
Occur between non metal elements
8
Q
Diatonic molecule
A
Two atoms covalently bonded
9
Q
Metallic bonding
A
A metal is made up of positive and free electrons
Results from the attraction between the positive ions in s regular lattice and the delocalised electrons
10
Q
Ion
A
A charged particle formed when an atom gains or loses electrons
