Answer: to achieve a stable octet of electrons in their outer shell
Explanation:
- Sodium (Na) has an atomic number of 11, and an electronic configuration of 1s2, 2s2 2p6, 3s1.
- Chlorine (CI) Sodium (Na) has an atomic number of 17, and an electronic configuration of 1s2, 2s2 2p6, 3s2 3p5.
Hence, sodium donates its single valence electron to chlorine, thereby achieving a stable octet structure of 1s2, 2s2 2p6 while chlorine accept the single electron also forming a stable octet structure of 1s2, 2s2 2p6, 3s2 3p6. Therefore, the reaction yields NaCl, an ionic compound with ionic (electrovalent) bond.
Na + Cl --> NaCl
Thus, Sodium(Na) and Chlorine (CI) want to form a lonic Bond because both acheive a completely filled outermost shell (octet structure)

True or False. The answer to the question
Answer:
bro what.
Explanation:
... is this an actual physics question?
Answer = 31.5J (rounded to 1dp)
The question wants to find the work done, where work done can be calculated in the equation:
Work done = Force x Distance
The force is not given in the question, however they give the acceleration and mass, so you can calculate the force using Newton's second law:
Force = Mass x Acceleration
First, calculate the force. The mass is 45kg for the 3 boxes and the acceleration is 12.3m/s^2.
Force = 45 x 12.3
Force = 553.5N
Now that you have the force (553.5N) and distance (57cm), substitute those values into the equation for work done.
Make sure to convert the 57cm into metres (into SI units), otherwise the answer would be wrong.
57cm = 0.057m
Work done = Force x Distance
Work done = 553.5 x 0.057
Work done = 31.5J (rounded to 1dp)
