According to the kinetic theory of matter, which of the following statements is true about matter? * the atoms and molecules of a substance are always in motion. the higher the temperature of a substance, the faster its particles move. more massive particles move more slowly than less massive particles. all the above

The true statements regarding the matter should be all of the above.

In the case of this theory, the atom and molecules should be always in motion. Also, if the temperature of the substance is higher so the movement of the particles should be quicker. Also, the massive particles should be move more in a slow way as compared to the less massive particles.

The answer is all of the above..

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
