Answer:
The statement which defines activation energy is that it is the difference between reactant energy and maximum energy.J
Explanation:
A reaction that does not have activation energy will not take place at all.
Answer:
Atomic #: 82
Mass #: 206
Charge: 4+
# of protons: 82
# of electrons: 78
# of neutrons: 124
Explanation:
Atomic #: look at the bottom left #, it's always the atomic #.
Mass #: look at the top left # it's always the mass #.
Charge: they give you the charge which is shown on the upper right of the element.
# of protons: is the atomic #
# of electrons: also the atomic # minus 4 bc the charge is a positive 4, indicating that some electrons 'left'.
# of neutrons: 206 (mass # is protons + neutrons) minus 82 (atomic#) which is 124.
