An office worker at the Universal Space Agency returned from lunch to find someone left him a gift—a cold can of soda to drink! But when the office worker picked up the can, he realized it was wet. The can was covered in a thin layer of liquid. Some of the liquid was slowly dripping onto his desk. What kind of liquid is on the officer worker’s soda can, and how did the liquid get onto the surface of the can? Using evidence from the articles you have read as well as the Sim and other activities you have completed in this lesson, write down your initial ideas about why this mystery occurred. Be ready to share your ideas.

nanotechnology is a powerful tool in biomaterials research as it creates numerous possibilities for the engineering of functional molecules. nano-bio refers to projected ability to incorporate biomimicry into various materials at nanoscale.  

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
