The answer choice which represents an aspect of the kinetic-molecular theory and can be used to explain compressibility of plasma is; Particles move independently of one another and are widely spaced.
<h3>What is the kinetic-molecular theory?</h3>
The kinetic-molecular theory in discuss postulates about the states of matter.
Also, it is built upon the idea that matter is composed of tiny particles that are constantly in motion.
Hence, the theory is explanatory of the observable properties and behaviours of solids, liquids and gases and hence, explains the compressibility of plasma.
Remarks;
- Particles move independently of one another and are widely spaced.
- Particle kinetic energy increases with increasing temperature.
- Particles exert no attractive or repulsive force on one another.
- Particles always move even when they have fixed positions.

Answer:
1. Diagram C.
2. Diagram A.
Explanation:
1. Calcium atom, Ca has 20 protons and 20 electrons. On the other hand, Calcium ion, Ca^2+ has 20 protons and 18 electrons. This is true because the +2 charge on the calcium ion, Ca^2+ indicates that the calcium atom, Ca has loss 2 electrons.
From the above illustration we can say that calcium ion, Ca^2+ has the following:
Proton = 20
Electron = 18
Therefore, diagram C indicates calcium ion, Ca^2+.
2. Fluorine atom, F has 9 protons and 9 electrons. Fluoride ion, F¯ has 9 protons and 10 electrons. This is so because the –1 charge on the fluoride ion, F¯ indicates that the fluorine atom, F has gained 1 electron.
Thus, we can say that the fluoride ion, F¯ has the following:
Proton = 9
Electron = 10
Therefore, diagram A represent fluoride ion, F¯.
Dull (not shiny)
poor conductors of heat and electricity (they are insulators)
weak and brittle (they easily break or shatter when solid)
Answer:
The characteristic of silicon that is most closely related to its chemical reactivity is that;
It is found in nature in mainly as oxides and silicates
Explanation:
Silicon, which is a member of group 14 of the periodic table has the electron configuration of [Ne]3s²3p² and has a high affinity for oxygen such that the the oxides are known as silicates and it is almost impossible to find pure silicon in nature and it is found in the universe as silica and silicates
Silicate minerals make up over 90% of the Earth's crust such that, by mass silicon is only surpassed by oxygen as the most abundant element found in the Earth's crust.
