How did later discoveries change the model of mendeleev's periodic table to what we accept today? a) mendeleev's periodic table was labelled as inaccurate and his founding principles were scrapped. b) elements were arranged by atomic number and properties of the elements varied periodically with atomic number. c) while elements are arranged by atomic mass number, known families of elements are organized by electron number. d) elements were arranged by the mass number of the nucleus and properties of the elements varied periodically with mass.

The earth is constantly spinning on its axis, like you might spin a basketball on your finger. it is this spinning of the earth that causes

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
