Protons, neutrons and electrons - ANSWER What are the three sub-atomic particles
you would find in atom?
Protons, and neutrons - ANSWER Which sub-atomic partilces would you find in the
nucleus of an atom?
The shells - ANSWER Where would you find the electrons in an atom?
+1 - ANSWER What charge does a proton have?
0 - ANSWER What charge does a neutron have?
-1 - ANSWER What charge does an electron have?
1 - ANSWER What is the relative mass of a proton?
1 - ANSWER What is the relative mass of a neutron?
0.005 - ANSWER What is the relative mass of an electron?
This is the number of protons in the nucleus (smallest number on the periodic table).
- ANSWER What is the Atomic Number?
This is the number of protons + neutrons in the nucleus (largest number on the
periodic table) - ANSWER What is the Mass Number?
Number of neutrons = mass Number - atomic number - ANSWER How do you work
out the number of neutrons in an atom from atomic number and mass number ?
On the left hand side - ANSWER Which side of the periodic table would you find
metals?
It is a vertical column, all elements in the same group have similar properties and the
same no. of electrons in the outside shell - ANSWER In the periodic table -what is a
group? -what do elements in the same group have in common?
These are horizontal rows across the periodic table, elements in a period have
different properties. - ANSWER In the periodic table, what is a period?
Isotopes of the same element have the same number of protons but have a different
number of neutrons. - ANSWER What is an isotope?
(mass of isotope 1 x % abundance) + (mass of isotope 2 x % abundance) ... and
then divide the answer by 100 - ANSWER What is the formula to calculate the
Relative atomic mass for an element with two isotopes?
