The metals are the elements that more easily can lose electrons to fill their outermost shell. And among the metals the alkalyne are most likely than alkalyne earth and these are most likely than other metals.
As less electrons the metal has in its outermost shell the more likely it will lose an electron fo fill its outermost shell.
So, Li, Na, K, Rb, Cs, and Fr have one electron in their outermost shell, so they are more likely to lose an electron to fill their outermost shell than Be, Mg, Ca, Sr, Ba, Ram which have two electrons in their outermost shell.
Using the same reasoning, Be, Mg, Ca, Sr, Ba, Ra are more likely to lose an electron to fill its outermost shell than Al, Ga, In, Tl.
Al, Ga, In, Tl are more likely to lose an electron than Si, Ge, Sn, Pb.
Si, Ge, Sn, Pb are more likely to lose an electron than O, S, Se, Te, Po
O, S, Se, Te, Po are more likely to lose an electron than F, Cl, Br, I, At
F, Cl, Br, I, At (halogens) and He, Ne, Ar, Kr, Xe, Rn (noble gases) will not likely lose electrons.
200 ms² is the kinetic energy for an object that weighs 40g and moving at 10 m/s.
<h3>What are kinetic energy ?</h3>
Kinetic energy is the power that an object has had as a result of motion. To accelerate an object, a power must be supplied to it. To apply a force, we must exert effort. The power is transported to the object when work is accomplished, which causes it to move at a new, constant pace.
<h3>What makes kinetic energy so important?</h3>
The capacity to perform work is unquestionably the most important characteristic of kinetic energy. Force acting on to an object while it is traveling is referred to as work. Energy and work are interchangeable because of their close relationship.
<h3>Briefing:</h3>
Using Kinetic Energy Formula:
K.E = 1/2 mv²
K.E. = 1/2 * 40 * 10
K.E. = 200 ms²

Answer:
The final displacement of the car is 140 meters.
Explanation:
The final displacement of the car (), in meters, is the sum of the change in displacement associated with each part of the journey, which is derived from the following kinematic formulas:
(1)
(2)
(3)
(4)
Where:
- Traveled distance of the first part, in meters.
- Traveled distance of the second part, in meters.
- Acceleration in the first part, in meters per square second.
- Acceleration in the second part, in meters per square second.
- Initial speed of the car in the second part, in meters per second.
- Time taken in the first part, in seconds.
- Time taken in the second part, in seconds.
If we know that , , and , then the distance traveled by the car is:
By (2):
By (3):
By (4):
By (1):
The final displacement of the car is 140 meters.
