Which answer choice correctly describes how mendeleev predicted new elements? mendeleev organized elements so that their atomic mass increased from right to left. mendeleev arranged elements into a table and left gaps and descriptions of expected properties based on inconsistencies in atomic number. mendeleev organized elements into a table and left gaps based on patterns he saw. mendeleev arranged elements into groups with similar physical properties.

The answer is Mendeleev arranged elements into a table and left gaps and descriptions of expected properties based on inconsistencies in atomic number.

In Mendeleev 's periodic table, a large part, is attributed to the gaps which he predicted would contain undiscovered elements with predictable properties. That is the main reason of the success of his periodic table.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
