Answer: Titanium has 22 protons
Explanation: If an atoms donates 4 electrons, it forms cation with charge +4. So original atom have 22 electrons and because atom is neutral, it has 22 protons. Number of neutrons does not matter, there are more neutrons than protons in heavier atoms.
Answer:
The log will float on the water because its density is lower than the liquid, so it will stay at the top due to Archimedes' principle.
I believe the correct answer from the choices listed above is the last option. The term that would best describe the <span>role of hydrogen gas in the formation of a water molecule would be a reactant. Water has a formula of H2O where it contains water so it should be that hydrogen is a reactant. </span>
That would be A.
2.5*2*10^(10-7)=5*10^3
The atomic number tells us the number of protons and electrons.
The atomic mass tells us the weight of the nucleus, which is the amount of protons and neutrons
