Minerals to Metals Part 5 Flashcards
What is the electronic configuration of an element?
The number of electrons in each shell they contain
Eg: Magnesium = (2,8,2)
What happens the further apart an element is from another element in the same group?
The less likely they are to have similar chemical properties
What does increasing atomic number generally coincide with?
Increasing atomic mass
What does the period number of an element tell you?
The number of electron shells the element has
All metals are found on the left side of the periodic table, apart from which one?
Hydrogen
What are non-metals and metals separated by?
Metalloids
How are the metals aluminium, calcium, magnesium, potassium and sodium obtained by?
Electrolysis, which involves passing electricity through their molten oxides or chlorides
How are the metals copper, iron, lead, mercury, silver, tin and zinc obtained?
Heating the metal ores in a furnace
What is the reactivity of alkali metals, alkaline earth metals, halogens and noble gases?
Alkali Metals = Reactive
Alkaline Earth = Hard, Less Reactive
Halogens = Reactive
Noble Gases = Non-Reactive
What is an electron?
A particle with a negative charge
What is an element made up of?
Atoms which all have the same atomic number
What is an ion?
Charged particle which has a different number of protons and electrons
What does an isotope have?
The same number of protons but different number of neutrons
What is a molecule?
The smallest bit of a substance which can normally exist
What is an electron?
A particle with a negative charge
