Resumen del Recurso
Chemistry 1 - A
Atoms
ATOMS are small units of matter that can take place in chemical reactions
Atoms have the same number of electrons as protons
Proton = Electron
They have no overall charge so are NEUTRAL
If electrons are added or removed, the atom becomes CHARGED and is then an ION
Two or more atoms make a MOLECULE
Element
An ELEMENT is a substance made up of just one type of atom
When an element reacts with another element, a COMPOUND is formed
Element + Element = Compound
COVALENT BOND
IONIC BOND
METALLIC BOND
If two or more elements are not joined together, this is called a MIXTURE
Each element has atoms with different amount of protons
Structure of the atom
The middle of the atom is called the NUCLEUS
In the nucleus there are PROTONS and NEUTRONS
PROTONS are positively charged
NEUTRONS have no charge
SO the nucleus has an overall positive charge
The ELECTRONS move around the nucleus
ELECTRONS are negatively charged
They occupy shells around the nucleus
