How does water h2o and hydrogen peroxide h2o2 illustrate the law of multiple proportions?

Law of multiple proportions: statement that when two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers

H2O has a H:O proportion of 2:1

while H2O2 has a H:O proportion of 2:2

different proportions, same elements

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

mark brainliest and have a great day!

indium, and thallium have three electrons i think
