Answer:
True
Explanation:
An atom's valance electrons are those electrons that have the highest energy. Atoms tend to be stable and nonreactive if they have the highestvalence electrons. In the periodic table, the number of valence electrons in each element decreases from left to right across each period.

The galaxies are in constant motion so it can be inferred that their position will not be the same as a hundred million years ago.
A galaxy is a term to refer to the set of stars, gas clouds, planets, cosmic dust, dark matter, and energy gravitationally united in a more or less defined structure in the universe.
Galaxies are in constant motion because the elements that make them up are not static at any time; The galaxies rotate around the center of the galaxy. If they were still, the gravitational attraction would cause them to immediately fall towards the center of the galaxy: it is the same that would happen to the Earth and the other planets if they stopped rotating around the Sun, they would fall towards the Sun.
According to the above, it can be inferred that the galaxies after a while have moved from the place where they were last seen.
Note: This question is incomplete because there is some missing information. However, I can answer based on my general prior knowledge.

While travelling along a highway a drivers velocity is 9 m/s. In 12 seconds, the car has gone for 108 m.
<u>Explanation:</u>
The car travelling along the highway has a uniform velocity of 9 m/s. therefore to calculate the distance travelled by the car with the uniform velocity in 12 seconds, simple formula of velocity is to be employed.
Thereby, as we know that
The displacement is along the highway with uniform motion, therefore, distance=displacement
Given that,
Velocity = 9 m/s
Time = 12 s
Putting the values in the formula, we get,
Therefore, the car travels for 108 m in the 12 seconds while travelling along highway with 9 m/s of velocity.
