Revision ContentExam Question

Atoms are made up of protons, neutrons, and electrons.
Protons and neutrons form the nucleus of the atom in the centre, while electrons orbit in energy levels around the nucleus.
Protons have a positive charge, electrons a negative charge, and neutrons are neutral.
The atomic number of an atom is determined by the number of protons.
The mass number of an atom is the total number of protons and neutrons.
Atoms of the same element that have different numbers of neutrons are called isotopes.

Electrons occupy energy levels or shells around the nucleus.
The lowest energy level (closest to the nucleus) is filled first and can hold up to two electrons.
Subsequent levels can hold up to eight electrons.
The arrangement of electrons in an atom's energy levels is known as its electron configuration.
The periodic table is arranged in increasing atomic number, which determines an element's electron configuration.

The periodic table organises elements based on their atomic structure and properties.
The table is divided into groups (vertical columns) and periods (horizontal rows).
Elements within the same group share similar chemical and physical properties.
The group number corresponds to the number of electrons in the outer energy level.
The period number corresponds to the number of energy levels an atom has.

Elements on the left and centre of the periodic table are metals, those on the right are non-metals, and a zigzag line separates metalloids.
Metals are typically lustrous, malleable, and good conductors of heat and electricity.
Non-metals are typically dull, brittle, and poor conductors of heat and electricity but good insulators.
Metalloids have properties in between metals and non-metals.

Group 1: The Alkali Metals - These are very reactive metals that do not occur freely in nature.
Group 2: The Alkaline Earth Metals - These are metallic elements found in the earth's crust.
Group 7: The Halogens - These are reactive non-metals that occur naturally in various states of matter - Solid, Liquid, Gas.
Group 0/8: The Noble Gases - These are chemically inert non-metals.
