Answer:
A. Mass
Explanation:
Inertia is the resistance of an object to any change in its velocity. Inertia depends only on the mass of the object: the greater the mass, the larger the inertia of the object, because it will be more difficult to change the velocity of the object.
An example to better understand: assume there is a golf ball rolling with a certain speed, and a car moving with the same speed. If we want to stop the two objects, we will need a much larger force for the car, because its mass is much greater than the gold ball, so it has much more inertia than the golf ball.
<span>An element with 1 valence electron has a charge of -1, because there is an extra negatively charged electron attached to the ion.</span>
Answer:
9 electrons
Explanation:
The structure has 9 protons and hence the number of electrons equals the number of protons that's why it is said to be electrical neutral
Hello!
In chemistry, atomic mass is normally written in amu. This stands for atomic mass units.
Within an atom, there are three main parts: protons, neutrons, and electrons. Between these three, electrons are extremely light. However, protons and neutrons both weigh 1 amu.
Thus, this means to get the atomic mass, add together the protons + neutrons.
Hope this helps!
