Answer: A) Two atoms share electrons so they can fill their outer shells
Explanation: A covalent bond is a type of bond formed by sharing equal number of electrons between two non-metal atoms so that both of them can attain a stable octet or duplet structure of noble gases.
In covalent bonding, there is no loss or gain of electrons between atoms. For example, the formation of chlorine molecule, chlorine atom has seven electrons in its outermost shell, remaining one electron to attain an octet structure of noble gases. Two chlorine atoms share one pair of electron, each chlorine atom donating one electron to form a pair so that each atom in the chlorine molecule attains an octet structure..

Hi
The purpose of writing a lab report mainly is to describe the results of your experiment and the learning outcome of your performed experiment as well.
Here are some important parts of a lab report:
Title Page:
It is not mandatory but it is good to add a title page for overall presentable formatting. It will include the title of your experiment, your name and also if there is a partner his name, the name of your lab as well as supervisor's name, along with the date experiment was performed.
Purpose/Introduction:
It is few paragraphs long tat explains the main objectives of your experiment. It may also include the results as well as the hypothesis and barf conclusion of experiment.
Materials and Methodology:
This includes the protocols you followed for carrying out a certain experiment and also the main items you used to exectute the experiemnt like equipment, chemicals etc.
Data:
The numerical data you obtain from an experiment can look presentable if you write in the form of table.
Results
It is just an representation of your data in forms of sentences that and results are close to predictable findings and how reliable they look.
Analysis or Discussion
Here you discuss your results that how they are similar or different to the experiments of similar nature that are already conducted. You can give your opinion as per your knowledge and interpret your results so that they make a sense for the reader.
Conclusions
Just conclude the report in one small paragraph that how your experiment accepted or rejected your hypothesis.
Figures or graphs:
You can include some figures and graphs that support your experiment.
References:
Here you will add the links or citations of the work that helped you in carrying out experiment or writing the lab report like journal articles, website articles etc.
Hope it help!
