Answer:
The iron atom has a positive charge, making it a cation.
Explanation:
The atom has a nucleus, where the protons and neutrons, which are the subatomic particles with the highest mass, are located. Practically all the mass of the atom is concentrated in the nucleus.Protons have a positive electrical charge, while neutrons have no charge.
Electrons move around the nucleus with other negatively charged particles.
An iron atom (Fe) has 26 protons and 20 electrons in it. That is, there are 6 more protons than electrons. As mentioned, protons are positively charged. So <u><em>the iron atom has a positive charge, making it a cation</em></u>.
Answer:
Explanation:
We use the kinematics equation to solve this question:
because the ball is dropped
the acceleration is the gravity, negative because it points downwards
initial height
final height
So:
The transfer of heat through flowing material is convection
