C6 Reactions Of Metals Flashcards
Reactivity?
How vigorously a substance chemically reacts
How can metals 🤘 be ordered 📑 by their reactivity?
By comparing their reactions with water 💦, acid or oxygen
What name is given to a list of metals ordered 📑 by their reactivity?
Reactivity series
In terms of electrons, what makes some metals more reactive than others?
They lose their outer shell 🐌 electron(s) more easily
Y r gold and silver found 🔍 naturally as elements in the Earth’s crust?
They r very unreactive
Ore?
Rock 🗿 containing enough of a metal compound to be economically worth extracting
How r metals less reactive than carbon extracted from their ores?
Carbon Reduction
In terms of oxygen, what is oxidation?
Addition of oxygen
In terms of oxygen, what is reduction?
Removal of oxygen
Y can metals like potassium and aluminium not be extracted by reduction by carbon?
They r more reactive than carbon
How r metals more reactive than carbon extracted from their ores?
Electrolysis
Displacement reaction?
When a more reactive substance takes the place of a less reactive substance in a compound
Ionic equation?
Equation which gives some substances as ions and has spectator ions removed ❌
What type of substance is given as ions in an ionic equation?
Ionic compounds in solution (or liquid)
Spectator ion?
Ion that is unchanged in a reaction
Half equation?
An equation that shows 📺 whether a substance is losing or gaining electrons
In terms of electrons, what is oxidation?
Loss of electrons
In terms of electrons, what is reduction?
Gain of electrons
