Answer:
The superscript after the letter
tells us the electrons are in the n=2 energy level.
Explanation:
The atomic number is the same as the amount of electrons and protons. For example:
Oxygens atomic number is 8 so the proton and electron count is 8.
Hydrogens atomic number is 1 so the proton and electron count is 1.
Answer:
Number of neutrons in the nucleus.
Explanation:
Mass number is protons plus neutrons. Protons do not change from isotope to isotope
Answer:
Image result for How do solute concentrations affect the rate of osmosis within the cell?
Concentration gradient - The movement of osmosis is affected by the concentration gradient; the lower the concentration of the solute within a solvent, the faster osmosis will occur in that solvent.
I think this is it^^^
Explanation:
Answer:
33atoms
Explanation:
An atom is the smallest particle that can take part in a chemical reaction.
The given compound is:
3(NH₄)₂S
Here we have 3 moles of (NH₄)₂S ;
So:
Total number of atoms:
2 atoms of N
2 x 4 atoms of H
1 atom of S
Total = 2 + 8 + 1 = 11 atoms
So;
The total atom = 3 x 11 = 33atoms
