Earlier, we stated Newton's first law as “A body at rest remains at rest or, if in motion, remains in motion at constant velocity unless acted on by a net external force.” It can also be stated as “Every body remains in its state of uniform motion in a straight line unless it is compelled to change that state by forces
For example-A stationary object with no outside force will not move. With no outside forces, a moving object will not stop. An astronaut who has their screwdriver knocked into space will see the screwdriver continue on at the same speed and direction forever.
Here, we are required to determine which element has atoms with Valence electrons in a higher energy level than those of calcium.
The Valence electrons of the Caesium, Cs atoms has higher energy level than those of Calcium.
First, we need to determine the electronic configuration of each of the elements
- Therefore the Calcium electron configuration will be:
- 1s²2s²2p⁶3s²3p⁶4s²
- Therefore, for Cs Electron Configuration:
- 1s² 2s²2p⁶3s²3p⁶3d¹⁰ 4s²4p⁶4d¹⁰ 5s²5p⁶ 6s¹
- Therefore, For lithium, The electron configuration of lithium is :
- 1s²2s¹
- For oxygen, Therefore the O electron configuration will be:
- 1s²2s²2p⁴
- For bromine, the electronic configuration is 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁵
Among the elements in the option, the Valence electrons of the Caesium, Cs atoms has higher energy level than those of Calcium.
This is so because the only Valence electron of Cs is located in the 6s orbital and as such has the highest energy level amongst all of the elements.

The acceleration due to gravity on Jupiter is 24.79 m/s²,
compared to 9.8 m/s² on Earth ... a ratio of about 2.53 .
So if a person or object were somehow transported to Jupiter,
he/it would weigh
(2.53) times (Earth weight)
there.
