charge and mass of an electron
-1 mass= very small
1 of 19
charge and mass of a neutron
0 mass=1
2 of 19
charge and mass of a proton
+1 mass=1
3 of 19
What are isotopes
different versions of an elements with the SAME AMOUNT OF PROTONS but A DIFFERENT AMOUNT OF NEUTRONS
4 of 19
what does the structure of an atom look like
nucleus containing the neutrons and protons and shells around
5 of 19
what are the electronic configuration rules
1st shell-2 2nd shell-8 3rd shell-8 4th shell-2
6 of 19
what is an element
contains only one of type of atom
7 of 19
what is an compound
two or more different types of elements joined together
8 of 19
what is mixture
two or more atoms/elements/compound which are mixed together but not joined
9 of 19
when is an element most stable/unreactive and why
when it's outer shell is full because they don't need to gain or lose electrons so don't react
10 of 19
what are group zero elements
elements that are the most stable as they have a full outer shell
11 of 19
what is formed when an atom gains/loses electrons
Ions
12 of 19
what type of ion is formed when an element LOSES an electron
a CATION
13 of 19
what type of ion is formed when an element gains an electron
a ANION
14 of 19
why do elements react
TO GET A FULL OUTER SHELL
15 of 19
what are subatomic particles
they make up a particle/atom
16 of 19

oxidised
17 of 19
when an atom loses an oxygen it is ?
reduced
18 of 19
what is the periodic table
a way to organise and arrange elements to be able to present information about these elements in a clear way
