Please fill in the following by ticking the boxes to show how well you have
understood topic 3
1) I know that Elements can be classified in different ways e.g. naturally occurring/man made,
solid/liquid/gas, metal/non metal
2) I know that Chemists have classified elements by arranging them in the periodic table
3) I know Families of elements: halogens (group 7), alkali metals (group 1), noble gases
(group 8/0) and transition metals (middle block)
4) I know that Every element is made up of very small particles called atoms
5) I know that Atoms of different elements are different BECAUSE they have a different
number on the periodic table called the atomic number
6) I know that Atoms of different elements vary in size and in mass
7) I understand that An atom is neutral because the positive charge of the nucleus is equal to the
sum of the negative charges of the electrons.
8) I understand that An atom is neutral because the numbers of protons and electrons are equal
9) The atom has a very small positively charged nucleus with negatively charged electrons
moving around outside the nucleus
10) I know that The 3 sub particles in an atom are: protons, neutrons and electrons
11) I know that Protons are positive and are located in the nucleus
12) I know that Neutrons are neutral (have no charge) and are located in the nucleus
13) I know that Electrons are negative and spin around outside the nucleus
14) I know that Protons have a mass of 1 amu. Neutrons have mass of mass of 1 amu Electrons
have no mass
15) I know that Atoms have a mass number which equals the number of protons plus neutrons
16) I know that Elements with the same number of outer electrons have similar chemical
properties
17) I know that Isotopes are atoms with the same atomic number but a different mass number
