B - Atomic number. Dmitri Mendeleev organised the table according to atomic weight, however this caused problems with elements such as iodine and tellurium, Iodine has a higher mass, but a lower atomic number. And to make iodine in the same group as similar elements (halogens), Mendeleev had to break his own rules and put it before tellurium in the table. Moseley fixed this problem by ordering the elements according to atomic (proton) number.

An electron in a hydrogen atom moves from level 1 to level 4. The electron then drops from level 4 to level 2. Which
alexira [117]

Answer:

The energy absorbed in the first move is greater than the energy released in the second move.

Explanation:

When the electron goes up levels it absorbs energy to enter that higher energy state. When it goes down, it releases energy but just not as much because 1-4 is more than 4-2.

What is equal to the number of particles in 24 grams of carbon-12? 2 moles 2:1 mole ratio 2:1 molar mass 1:2 molar volume
mariarad [96]

Answer:

The answer to your question is 2 moles of Carbon

Explanation:

Carbon-12 means it has a molecular mass of 12g / mol. Mol is defined as the number of grams of an atom in one mol.

To solve this problem, we use proportions

                                    12 g of Carbon ---------------- 1 mol of Carbon

                                     24 g of Carbon --------------   x

                                     

                                      x = ( 24 g x 1 mol ) / 12 g

                                      x = 24 / 12

                                     x = 2 mol of Carbon
