Answer:
10: Number of protons always equal number of electron, but that's the case with a neutral atom. ... This implies that it has same number of protons and electrons in it. It means it has same amount of positive and negative charge, which cancel each other, and the atom as a whole becomes electrically neutral.
19: The three stable isotopes of Argon, Argon-36, Argon-38, and Argon-40, would all have 18 protons and 18 electrons if they are all neutral. The three isotopes will have different numbers of neutrons compared to each other (18, 20, and 22 neutrons respectively).
20: This isotope of fluorine has 9 protons, 9 electrons and 10 neutrons.
Explanation: Hope those are the only answers you needed. I just saw the stars next to them and figure those were the only ones you needed.

Answer:
The lowest level, which is usually the producers.
Explanation:
This is because on every level of the trophic system, some energy is lost before the next level. So the level with the least lost energy is the lowest
The average height of the oceans surface between high and low tides is called the sea level. It is important to know this measurement because with this it is possible that we can calculate the height of anything on the land. Also, we can <span> calculate the height of anything on the land. Also, we can be able to determine whether the oceans are falling or rising through time.
So the answer is </span><span>Sea level </span>
