1
New cards

Chemical reactivity

The electrons, especially the outer electrons, determine chemical reactivity.

2
New cards

Chemical properties

The outer electrons and how they interact with other electrons (either gaining or losing them) are key in determining chemical reactivity.

3
New cards

Gold's chemical reactivity

Gold's outer electrons do not want to be lost or gain other electrons, making it unreactive.

4
New cards

Reactive metals with acids

Zinc and magnesium are very reactive because they readily give away their outer electrons.

5
New cards

Combustibility example

Methane (CH4) is highly reactive with oxygen and easily catches fire, making it highly combustible.

6
New cards

Water's reactivity with oxygen

Water does not catch on fire, so it is unreactive with oxygen.
