Answer: The number of energy levels increases as you move down a group as the number of electrons increases. Each subsequent energy level is further from the nucleus than the last. Therefore, the atomic radius increases as the group and energy levels increase.
C: Solution is another name for Homogenous mixture
Answer:
B
Explanation:
Im sorry if im wrong im still new to this
The answer is: B. Collisions between gas particles are elastic; there is no net gain or loss of kinetic energy.
The Kinetic Molecular Theory of Matter
1) Matter is composed of tiny particles (in this example oxygen molecules).
2)These particles are in constant, random motion and possess kinetic energy.
3) The particles also have potential energy due to intermolecular attractions.
4) The average kinetic energy increases as the temperature increases.
5) Energy is transferred from one particle to another during collisions, but at constant temperature the total energy of the system is constant.
Kinetic energy is energy associated with motion.
Definition of valence electron. : a singleelectron or one of two or more electronsin the outer shell of an atom that is responsible for the chemical properties of the atom.
