Period: These are the horizontal rows that show the number of shells of electrons an atom has and are numbered from 1 - 7 E.g. elements in period 2 have two electron shells, elements in period 3 have three electron shells
IGCSE Chemistry Notes Chapter 3 The Periodic Table
The Periodic Table. Section 1: Understanding The Periodic Table. The periodic table is a table of chemical elements arranged in order of their relative atomic numbers.. The vertical columns are called 'groups' and the horizontal rows are called 'periods'.. Elements in the same group have the same number of electrons in their outermost shell and hence, have similar chemical properties.

The periodic table which also used to be known as the mendeleev table lists down all the elements which have been discovered till now. In the modern periodic table, the vertical columns are known as groups whereas the horizontal rows are known as periods. The elements are arranged in order of increasing atomic number.

2.2 recall the positions of metals and non-metals in the Periodic Table. From left to right across a period there is a gradual change from metal to non-metal elements. For example, in Period 3, sodium, magnesium and aluminium are metals. They all conduct electricity and their oxides are basic.

An atom is the smallest uncharged particle that can take part in a chemical change. An atom contains a centrally located nucleus. The nucleus contains positively charged protons and neutral neutrons. [Protons + neutrons= nucleon number or mass number] The electrons revolve around the nucleus in fixed orbits called electron shells or energy levels.
