BIOS 100 Exam
1. unique, defining property of atoms of a particular element:
Answer number of protons
- characteristics of atoms characteristics of electrons characteristics of both:
Answer smallest amount of defined by number of protons they contain substance composed of a single type of atom form of matter contain electrons
3. properties of hydrogen bonding between water molecules:
Answer slightly negative oxygen atom of one water molecule is attracted to the slightly positive hydrogen atom of another water molecule water is polar due to its bent structure and an unequal sharing of electrons
4. why doesn't oil dissolve in water?:
Answer water molecules form hydrogen bonds with each other and exclude oil molecules water molecules do not form strong attractions to nonpolar molecules, like the ones in oil
