Answer:
An atom changes from a ground state to an excited state by taking on energy from its surroundings in a process called absorption. The electron absorbs the energy and jumps to a higher energy level. In the reverse process, emission, the electron returns to the ground state by releasing the extra energy it absorbed.
Answer:
No.
Explanation:
He also created a telescope and formula for universal gravity.
Answer:
<h2>pH = 4.44 </h2>
Explanation:
The pH of a substance can be found by using the formula
where [ H+ ] is the hydrogen ion concentration of the solution
From the question
[ H + ] = 3.60 × 10^-5 M
So the pH is
We have the final answer as
<h3>pH = 4.44 </h3>

The closeness of a measurement to its true value is a measure of its accuracy. This term is the degree of which a certain measurement conforms to the correct value or the standard value. It is not the same with the term precision. Precision, on the other hand, is a measure used to characterize the closeness of the data measured.
They’re going to increase in atomic size based on how many electrons they have. You should be able to look at a periodic table or just look up how many electrons each of them has and then you can put it in that order
