The structure of each type of atom determines how many bonds it can make to other atoms. look at the reference material in section 2.4. which of the statements below is true?
a. nitrogen atoms are unstable, existing for only a matter of minutes or even seconds, before degrading into carbon and hydrogen.
b. a single carbon atom can partner with only one other atom at a time, although the range of potential partners is unlimited.
c. an oxygen atom can bind to two other atoms using single bonds or it can bind to just one other atom using a double bond.
d. a hydrogen atom can bind to up to four other atoms at once; this is why hydrogen is such an important element in our universe.

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
