The statement '<span>The more particles a substance has at a given temperature, the more thermal energy it has' is true. </span><span>The
kinetic molecular theory of gases has three main laws and one of them is the
average kinetic energy of the particles in a gas. The average kinetic energy of
the gas particles is the behavior and movement it does in the surroundings. It
is directly proportional to temperature wherein if you increase the
temperature, the kinetic energy of a particle also increases. It will also
decrease its movement or its kinetic energy if the temperature lowers. </span>
<span>The middle life crisis occurs for men at age of 39 and for women at age of 44. At this age, people start realizing that they are getting older and experience some physical changes which seem distressful for them.</span>
<span> It affects the sense of accomplishment and progress in career. Due to a midlife crisis, people start engaging in activities to cope with the reality such as wearing clothes that are fashionable, dating someone etc. Yes, I think I will also go through one because it happens with everyone in this age. It can be avoided by accepting the fact that these changes are reality and everyone have to face it one day.</span>
Answer:
D. Metallic atoms have valence shells that are mostly empty, which
means these atoms are more likely to give up electrons and allow
them to move freely.
Explanation:
Metals usually contain very few electrons in their valence shells hence they easily give up these few valence electrons to yield metal cations.
In the metallic bond, metal cations are held together by electrostatic attraction between the metal ions and a sea of mobile electrons.
Since metals give up their electrons easily, it is very easy for them to participate in metallic bonding. They give up their electrons easily because their valence shells are mostly empty, metal valence shells usually contain only a few electrons.
1. Our solar system is the only place in the universe where gravity played a key part in the formation of planets.
2. Rocky planets are small, dense, and orbit relatively close to the sun, compared to the Jovian planets, which are large, less dense, and orbiting far from the sun.
3. _______
