Answer: Option-A (<span> It would increase from bottom left to top right) is the correct answer.
Explanation: As we know converting solids into liquids and converting liquids into gases require energy. This energy provided increases the energy of the state and its particles start moving with higher velocities. Therefore, the energy of solids will be lower than liquids and gases respectively. While, liquids have greater energy than solids but less energy than gases. And, gases are the most energetic than solids and liquids.</span>
A) It would increase from bottom left to top right.
Explanation:
The energy that can be found in matter, is the energy of the particles moving inside it, so as you know in a solid state the particles move slower and are almost set still in a single spot, so the energy will increase as the substance goes from solid, to liquid to gas, because the energy in the particles will increase.
The number of dots an element has represented in the diagram, indicates how many valence eletrons( which is the number of electrons in the most exterior energy level of an atom or ion) the element has. So, 1 valence eletron equals one dot.
Group 2A — The Alkaline Earth Metals. Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
