Explanation:
Electrons are the right subatomic particle
First of all, that equation is not correct, which may be the reason
that you're having trouble assigning units to the quantities.
Power is defined as [energy / time], so [Energy] = [ power x time ],
and
[Time] = [ energy / power ].
Unit-wise, these equations are correct just as they appear here,
with no proportionality constants or conversion factors, when ...
[ Power ] = watts
[ Energy ] = joules
[ Time ] = seconds .
Answer:
15
Explanation:
The mass number is defined as the total number of protons and neutrons. The atomic number is total number of protons. And since we have the mass number and number of neutrons, we can use simple subtraction (30 - 15) to find that the atomic number is 15.
