17. Shapes and properties of molecules intro Flashcards
1
Q
What is the trend behind ionisation energies in the periodic table?
A
Effective nuclear charge increases from left to right → elements on the right side of the periodc table more likely to attract an electron than to give up
2
Q
Define electronegativity
A
ELectronegativity 0 the power of an atom in a molecule to attract electrons to itself
3
Q
What does the electronegativity of elements in a molecule determine?
A
The bond type
4
Q
What are the structures of solid compounds?
A
5
Q
How is the periodc table divided into metals and non-metals?
A
6
Q
Explain the bonding of binary compounds
A
7
Q
Explain ionic compounds and their properties
A
Arranged in a lattice - try to avoid contact
8
Q
What are the compound structures in period 3 oxides?
A
Ionic structures, covalent networks, covalent structures
