Test: Structure, bonding and the properties of matter - Question 3

What is the typical characteristic of a simple molecular structure?

Detailed Solution for Test: Structure, bonding and the properties of matter - Question 3
Simple molecular structures consist of discrete molecules held together by weak intermolecular forces, making them often soluble in water.
Test: Structure, bonding and the properties of matter - Question 4
Which property describes the compactness of a substance per unit volume?
Detailed Solution for Test: Structure, bonding and the properties of matter - Question 4
Density is the mass of a substance per unit volume. It indicates how tightly packed the particles are within a substance.
Test: Structure, bonding and the properties of matter - Question 5
In which type of bonding do atoms transfer electrons to form ions?
Detailed Solution for Test: Structure, bonding and the properties of matter - Question 5
Ionic bonding involves the transfer of electrons from one atom to another, resulting in the formation of oppositely charged ions.
Test: Structure, bonding and the properties of matter - Question 6
Which substance is likely to have the highest density?
Detailed Solution for Test: Structure, bonding and the properties of matter - Question 6
Metals like gold typically have high densities due to their closely packed metallic structures.
Test: Structure, bonding and the properties of matter - Question 7
What property allows metals to conduct electricity well?
Detailed Solution for Test: Structure, bonding and the properties of matter - Question 7
Metallic bonding allows delocalized electrons to move freely throughout the metal structure, enabling electrical conductivity.
Test: Structure, bonding and the properties of matter - Question 8
Which type of structure is formed by positive ions held together by electrostatic attraction to delocalized electrons?
Detailed Solution for Test: Structure, bonding and the properties of matter - Question 8
Metallic structures consist of positive ions surrounded by a 'sea' of delocalized electrons, contributing to their properties like malleability and conductivity.
Test: Structure, bonding and the properties of matter - Question 9
What is the characteristic property of an ionic lattice structure?
Detailed Solution for Test: Structure, bonding and the properties of matter - Question 9
Ionic lattice structures are brittle and typically non-conductive in solid state due to the fixed position of ions and lack of free electrons.
Test: Structure, bonding and the properties of matter - Question 10
What determines the properties of a substance in terms of hardness and melting point?
Detailed Solution for Test: Structure, bonding and the properties of matter - Question 10
The type of chemical bonding, such as covalent, metallic, or ionic, influences the physical properties like hardness and melting point of substances.
