Answer:
Protons and electrons
Explanation:
They have a different number of neutrons giving them a different atomic weight while having the same charge
The characteristic bright-line spectrum of an element is produced when its electrons return to lower energy levels To be in the ground state all electrons must be in their lowest energy state; all excited atoms must lose energy. The lost energy appears in the form of light. Hope this helped :)
Answer:
You see, plants need energy to grow and grow and grow. They use energy from sunlight to make a simple sugar, glucose. Whenever the plant needs energy, it can chomp a little glucose off of the starch.
without energy it wont get energy/food so it will eventually die
Explanation:
Answer:
The electron cloud
Explanation:
<em>Rutherford’s gold foil experiment</em> showed that the atom consisted of a tiny nucleus inside of a much larger electron cloud.
The diameter of the electron cloud is about 50 000 times that of the nucleus.
The question is too broad. Depends of the battery and depends where do you connect it to.
define first a battery reaction and where it is connected to define if the reaction is endo or exothermic.
If a battery reaction is exothermic when it is connected to a circuit may be endothermic when it is charged (reverse reaction).
some batteries at low temperature tends to work less, that suggest, they may need absorb some energy from the surroundings.
