1
New cards
Metals and non
metals both react with oxygen
2
New cards
If the metal oxide dissolves in water
the metal oxide will produce an alkaline solution.
3
New cards
The properties of metals are
Good conductor of electricity and heat, Malleable, ductile, possess metallic luster and solid at room temperature.
4
New cards
Non metals are on the
right side of the periodic table
5
New cards
Metals and Non metals react with oxygen to form an..
oxide
6
New cards
What happens when a non metal oxide is dissolved in water
it will produce an acidic solution.
7
New cards
The properties of non metals are
Bad conductors, brittle, non ductile, they don’t possess metallic luster and are any state at room temperature
8
New cards
Electrons orbit
the nucleus in shells
9
New cards
Different shells hold
a different number of electrons
10
New cards
Shell 1 holds
2 electrons
11
New cards
Shell 2 holds
8 electrons
12
New cards
Shell 3 holds
8 electrons
13
New cards
Shell 4 holds
18 electrons
14
New cards
You can use the periodic table to
help you work out the electronic structure.
15
New cards
The group tells you
how many electrons there are in the outer shell
16
New cards
the period tells you
how many shells there are.
17
New cards
An ion is
a charged atom
18
New cards
What is oxidation.
When a metal loses electrons to become a positive ion
19
New cards
The number of protons and neutrons
doesn’t change when forming an ion.
20
New cards
An atom will
gain or lose electrons to have a full outer shell.
21
New cards
An ionic bond is
a strong electrostatic attraction between oppositely charged ions.
22
New cards
When a metal reacts with a non metal
electrons are transferred from the metal atom to the non metal atom so both achieve more stable electronic structures, with full outer shells.
23
New cards
Ionic bonding is shown
using a dot and cross diagram
24
New cards
Ionic compounds have
high melting points and boiling points.
25
New cards
Ionic compounds form
a giant ionic lattice
26
New cards
When ionic compounds are solids
they can’t conduct electricity
27
New cards
When ionic compounds are molten or dissolved
they ions are free to move, so they can conduct electricity.
28
New cards
A covalent bond is
where two non metal atoms share a pair of electrons, so that they both have a full outer shell.
29
New cards
A covalent bond is
strong.
30
New cards
In between the molecules there are
weak intermolecular forces which don’t need much energy to overcome, meaning they have a low melting and boiling point.
31
New cards
The larger the molecule
the stronger those forces are and therefore the higher the melting/boiling points are.
