The elements are identified by its aomic number and they are placed in the periodic table in ascending order of atomic number.
There is one unique element for a given atomic number.
For example, atomic number 1 identifies Hydrogen and there cannot be another different element with the same atomic number.
All the elements with atomic numbers from 1 to 118 have been discovered. So, you know that there is not room for new products with atomic number equal or less than 118.
Answer:
Explanation:
Hello,
In this case, Avogadro's relationship allows us to relate the moles and the volume of a gas at an initial condition and an a final one as shown below:
Thus, the volume that 0.00684 mol of neon the same pressure and temperature is computed below as required:
Best regards.
Answer:
it will eventually die off or eventually repopulate
Explanation:
Answer:
Al: 3
S: 6
Explanation:
