, Why do hydrogen bonds form between water atoms - Answer -water molecules are polar
- oxygen atom has negative charge and hydrogen atoms have positive charges;
negative atoms attracted to positive atoms of other water molecules
The atomic nucleus - Answer -The small, dense region consisting of protons and neutrons
at the center of an atom
Atomic number - Answer -the number of protons in the nucleus of an atom
atomic mass - Answer -the number of protons and neutrons in the atom
isotopes - Answer -Atoms of the same element that have different numbers of neutrons
valence electrons - Answer -Electrons on the outermost energy level of an atom
Relative potential energy of electrons - Answer -potential energy is the energy mater
possesses because of its location or structure (ex: the lone electron of a hydrogen atom and an
electron of a helium atom have equal potential energy)
Impact of unpaired electrons on the bonds formed by each atom - Answer -react readily
with other atoms or molecules and in a way that ends the condition of the unpaired electron
Covalent bonds - Answer -Bond where two atoms are connected to each other by the
sharing of two or more electrons
which types of atoms form covalent bonds with each other - Answer -nonmetals
