Periodic Table Flashcards
What are Columns and Rows
Columns are vertical also known as a Period
Rows are horizontal also known as a Group
Where are metals and non-metals
Metals are on the left
Non-metals are on the right
Why do elements in the same group have similar chemical properties
They have the same number of electrons in the outer shell
How can you tell if a substance is a metal or a non metal ?
metals conduct electricity and have alkaline based oxides whereas non-metals have acidic based oxides and do not conduct
Noble Gasses
Members
Helium Neon Argon Krypton Xenon Radon
Noble Gasses
Characteristics
Inert
Unreactive
Full outer shell of electrons
Alkali Metals
Members
Lithium Sodium Potassium Rubidium Caesium Francium
Alkali metals
Why are they reactive
I have one electron in the outer shell and therefore are reactive
Alkali Metals
Why are the lower elements more active in the higher ones
The electron is further away from the nucleus so the force of attraction is weaker meaning it will be lost easier
Halogens
Members
fluorine chlorine bromine iodine astatine
OIL RIG
meaning
Oxidation is the loss of electrons
Reduction is the gain of electrons
what is a redox reaction
where oxidation and reduction are happening at the same time
