 I am confident that I understand this and I can apply this to
problems
?

I have some understanding but I need to revise this some more
I don’t know this or I need help because I don’t understand it
National 4 outcomes are in lighter font.
in bold
National 5 outcomes are
Atomic structure and bonding related to properties of materials
Covered
()
1.An element is a simple substance containing only one type
of atom.
How well can you
do this?


2. State that everything in the world is made from about
100 elements

?

3. State that each element has a name and a symbol

?

4. Elements are classified in different ways, including
naturally-occurring/made by scientists, solid/liquid/gas,
metal/non-metal.

?

5. State that chemists have classified elements by
arranging them in the Periodic Table

6. A group is a column of elements in the Periodic Table

?

7. A period is a row of elements in the Periodic Table.

?

8. Identify the following families of elements:
the halogens
the alkali metals
the noble gases
the transition metals

?

9. State that elements in one group of the Periodic Table
show similar chemical properties

?

10. State that every element is made up of very small
particles called atoms

?

11. Describe the atom as having a vary small positively
charged nucleus with negatively charged electrons moving
around outside the nucleus
describe the location and charge of the proton, neutron and
electron

?

12. State the relative masses of the proton, neutron and
electron

?

13. State that an atom is neutral because the positive
charge of the nucleus is equal to the sum of the negative
charges of the electrons

?


14. State that atoms of different elements are different
and have a different number on the Periodic Table called
the atomic number
state that atoms of different elements have a different
number of protons, called the atomic number

?

15. State that an atom has a mass number which equals the
number of protons plus neutrons

?

16. Calculate the number of n, p and e from the mass
number and atomic number, and vice versa

?

17.State that an atom which has lost or gained
electrons is known as an ion.

?

18. Calculate the number of n, p and e from nuclide
notation, including ions, eg
