1. The chemical elements in the Periodic Table were originally arranged in order of their atomic ………………….
2. This list can then be arranged in rows so that elements with……………………………. properties are in the same vertical column, known as a………………………………………….
3. The horizontal row is called a…………………………….
4. In the modern periodic table elements are arranged in order of their atomic or…………………………………. number.
5. Argon is more like helium or ……………………………….. and not a bit like potassium.
6. Similarly potassium is more like lithium and ……………………………………. and so is better placed in Group ……………………………….. the "Alkali Metals"
7. The periodic table can also be seen as an arrangement of the elements in terms of their ……………………………….. structure.
8. Elements in the same group have the same number of …………………………………….. electrons.
9. More than three-quarters of the elements of the periodic table are…………………………………….
10. They are mainly found in the left hand columns (Group 1 and Group………………………………) and in the central blocks of …………………………………. metals.
11. They tend to be ……………………………………. in appearance, ……………………………………. conductors of heat and electricity and the melting and boiling points and densities tend to be …………………………………
12. About one quarter of the elements are………………………………….. and these can be gases, liquids or solids.
13. The solids tend to be …………………………….. in appearance and are ………………………….. conductors of heat and electricity. The boiling points and melting points and densities tend to be relatively…………………………...
