The temperature at which a solid changes to a liquid is called the
Freezing point
Melting point
Boiling point
A substance has a melting point of -10 0C and a boiling point of 30 0C. What state is it in at -17 0C?
Solid
Liquid
Gas
When atom loses or gains electrons they develop
energy
a charge
extra protons
When an atom loses electrons it becomes a
positively charged ion
negatively charged ion
an atom with no net charge
How many electrons does oxygen gain to become a negatively charged ion?
1
2
3
4
Group 7 Halogens have 7 electrons in their outer shell, when the halogen gains an electron it has a charge of
+1
-1
+2
-2
Ionic bonding occurs between a
Compounds
Metals
Metals and non-metals
Non-metals
Which is the correct definition of a covalent bond?
electrons shared between atoms to make compounds
electrons moved between atoms to make molecules
electrons shared between compounds to make molecules
electrons shared between atoms to make molecules.
Simple covalent molecules have low melting points because they have
Strong covalent bonds
Weak intermolecular forces
Strong intermolecular forces
Weak covalent bonds
Diamond is an example of a
simple covalent molecule
giant covalent structure
ionic compound
giant ionic lattice
Graphite conducts electricity because it
Has delocalised electrons between its layers
is metalic
is a giant covalent molecule
Metallic structures are typically strong because they
contain strong electrostatic forces
contain strong covalent bonds
contain strong ionic bonds
An alloy is a substance that contains
a mixture of two or more elements (both are normally different metals)
a mixture of halogens
nothing else, it is a pure metal
