A fluorine atom has 9 positive charge,9 negative charges and a mass of 19. Describe the structure of its atom.
Tanya [424]
The atomic structure of the atom contains 9 positively charged particles (protons) and 10 neutrally charged particles (neutrons) in the center of the atom in a clump called the nucleus. Those 9 negatively charged particles (electrons) are moving around outside of the nucleus.
There are 10 neutral charges, because the mass of 19 comes from the number of neutral charges plus the number of positive charges.
To calculate the number of neutral charges, subtract the positive charges from the mass (19 - 9), and you get the number of neutral charges (10).

Which cup has more thermal energy?
dybincka [34]

<em>Question: </em><em>Which cup has more thermal energy?</em>

<em>                   A. 2 liter cup of milk</em>

<em>                   B. 1 liter cup of milk</em>

<em>Answer: A. 2 liter cup of milk</em>

<em />

<em>Explanation:</em>

We have milk in both of the containers. The milk in both containers is the same temperature, so we will have to measure the amount of molecules. The amount of molecules makes it warmer, and if it is warmer, that is more energy. 2 liters have more thermal energy than 1 liter, because it has more molecules.

Our answer is 2 liter cup of milk.
