In order to determine the number of protons in 20.02 mol of Ne, we use Avogadro's number to convert the number of moles to number of atoms, 1 mol = 6.022 x 10^23 atoms. From there, we must know the number of protons in a Neon atom, which is 10. Thus, the formula will be:
(20.02 mol Ne)x(6.022 x 10^23 atoms/mol)x(10 protons/1 atom Ne) =
1.2056 x 10^26 protons
The probability of precipitation is low because the air is saturated with water vapor.
Answer:
Explanation:
Electrons have negative charge and they orbit around the nucleus.
Protons have positive charge and are inside the nucleus
Neutrons have neutral charge they are also inside the nucleus
the nucleus is the middle of the atom
the electron cloud is a cloud which the electrons travel around
An old star dies out, causing a supernova, causing hot gases to accumulate, creating the Sun.
