In 1913, Henry Moseley discovered a way to calculate the atomic number for each element and it was determined to arrange the per
iodic table by atomic number and not atomic mass. Why is atomic number the better way to organize the elements of the periodic table and not organizing by atomic mass? A.The atomic mass can vary based on the number of neutrons the atoms of the same element have, so the atomic mass may not be in order. Also, the atomic number is unique to each element.
B.The atomic number can be different for atoms of the same element, so it makes the patterns of the periodic table more varied.
C.The atomic number can vary based on the number of neutrons the atoms of the same element have, so the atomic mass may not be in order. Also, the atomic mass is unique to each element.
D.The atomic number and atomic mass are equivalent, so the atomic number is used because it is a smaller number
Answer is: unsaturated. Solubility of potassium chlorate on 70°C is approximately 30 grams in 100 grams of water. Solubility of potassium chlorate on 70°C is approximately 10 grams in 100 grams of water. So if dissolve 15 g of potassium chlorate in 201 g of water, there is less salt than it solubility and solution is unsaturated.
Electrons are particles that surround the nucleus of an atom like a cloud. As with protons and neutrons, electrons are essential to an atom's structure.
