Chemical properties of elements are primarily determined by the electrons but not by neutrons. Therefore, the isotopes of the same element have similar chemical behavior. (a) The atomic number is 17, so there are 17 protons and 17 electrons. The mass number is 35, so there are 18 (=35-17) neutrons. Hope this helps. :)
Answer:
protons, neutrons
Explanation:
There are three subatomic particles in all atoms: protons, neutrons and electrons. Of these three, only protons and neutrons are considered to have enough mass to contribute to overall atomic mass of the element.

he rise in the temperature from the sunlight results in the expansion of the water inside the syringe given the external temperature is higher than that of the fluid temperature. ... This is the reason for the little puddle of water to appear under the syringe tip after ten minutes in the sun.
Explanation:
What! Your teacher is crazy - half of those things will catch on fire if they are mixed! You should double check to make sure you have them written down right or you could really get hurt!
If you mix HNO3 and HCl you will get a brown gas (don't light it or smell it!). The one that is heavier is the HNO3, because it has more atoms in it. Then, mix the silver one (AgNO3) with KOH - it will give a silver coating to the plastic (search for Tollins Test to see what it looks like). DI water will absorb CO2 from the air and make carbonic acid, so the one that is acidic will be the water.
