Answer:
1.Fluorine is having 7 number of electrons and 1 makes bond.
Electronic configuration - 1S² 2S² 2P⁵
1 electron need to get in stable states 2P⁶.
2.Oxygen is having 6 balance electron and 2 makes bonds.
Electronic configuration - 1S² 2S² 2P⁴
2 electron need to get in stable states 2P⁶.
3.Nitrogen is having 5 balance electron and 3 makes bonds.
Electronic configuration - 1S² 2S² 2P³
3 electron need to get in stable states 2P⁶.
4. Carbon having 4 balance electron and 4 makes bonds.
Electronic configuration - 1S² 2S² 2P²
4 electron need to get in stable states 2P⁶.
Explanation:
Below is an attachment containing the solution.
The answer that you are looking for is D.
The distance the object willl fall durring the 2nd seconds is 4.9 m
<h3>Data obtained from the question</h3>
The following data were obtained from the question:
- Initial velocity (u) = 0 m/s
- Acceleration due to gravity (g) = 9.8 m/s²
- Time (t) = 2 - 1 = 1 s
- Height (h) =?
<h3>How to determine the distance the object will fall during the 2nd seconds</h3>
The distance the object will fall during the 2nd seconds can be obtained as follow:
h = ut + ½gt²
h = (0 × 1) + (½ × 9.8 × 1²)
h = 0 + 4.9
h = 4.9 s
Thus, the distance the object will during the 2nd seconds is 4.9 m
