Because Na has one too many electron to be stable, while Mg has 2. once they loose those electrons, they will be come ion. loosing one electron will give the ion a 1+ charge, and loosing 2 will create a 2+ charge
Answer:
They each contributed to the development of the atomic theory
Explanation:
They each contributed to the development of the atomic theory. ... Bohr said there was no certain path for electrons, and in the current theory, the exact path cannot be predicted. But there is an electron cloud.
A couple moment is produced when a network of forces do not have a resultant force, but only produces moment. As a result, it induces rotation without translation. That means the two forces are equal.
Moment = Force * Distance
In order to determine the vertical force, we must know the distance between the two forces which is represented by the length of the pipe. Suppose the pipe is 0.5 m, then the force is
400 N·m = F*0.5 m
F = 800 N
<span>It rises confidence for the reason that the more times you conduct the similar experiment over and over should either demonstrate your hypothesis right and wrong and remove any random incidences that might touch your results. Meaning it permits to have a more accurate measure or conclusion.</span>

I am not understanding your question
