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.

How oxygen is being transported?
About 97% of the oxygen used during breathing is delivered by red blood cells in the blood, while the remaining 3% dissolves in plasma. The pigment hemoglobin, which is found in RBCs, is what gives blood its red color. According to the partial pressures of oxygen, carbon dioxide, H+ concentration, and temperature, oxygen attaches to hemoglobin to create oxyhemoglobin. Up to 4 oxygen molecules can be carried by a single hemoglobin molecule. The optimum circumstances for the synthesis of oxyhemoglobin include low temperature, high H+ concentration, and oxygen partial pressure. In the alveoli, these criteria are satisfied. But in the tissues, the circumstances are different, and as a result, oxygen is separated from oxyhemoglobin.
