Answer:
Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. The loss or gain of valence electrons allows ions to obey the octet rule and become more stable. Therefore, ions combine in ways that neutralize their charges.
Explanation:
This kind of questions cannot be open because there might be many different answers depending of the focus.
In fact, I found the set of options that comes with this questions. This is:
A. behavior of ions.
B. molecular bonding.
C. molecular shape.
D. molecular motion.
Of course, the answer is the option D. molecular motion.
And, of course, you need an explanation.
It is good to know that the word kinetic refers to motion, so definetly kinetic molecular theory is a theory about the motion of the molecules.
With that you likely had been able to answer the question. But it is good to know what the molecular theory is.
The molecular kinetic molecular theory explains the properties and behavior of the gases in terms of the motion of its particles (molecules) making several assumptions about the energy, size and motion of such particles.
Answer:
2.89 g/cm^3
Explanation:
Since density equals mass over volume (or also seen as 
), simply divide 66.5 grams by 23.0 cm. This will output an answer of 2.89 g/cm^3.
He thought elements that haven't been discovered belonged in the place of the gap. He could also use the atomic mass of the missing elements
