Document Summary

Isotopes : versions of the same element but with diff number of neutrons: can be radioactive, have high energy--can intrude foods and kill microorganisms like bacteria. Ions : atoms with a diff number electrons than protons, causing them to be neg or pos charged. Ionic bonds: bonds that involve the transfer of one electron to another-making one pos and one neg: covalent bonds: bonds where each atom shares an electron with another atom i. ii. iii. Double bond : shares two pairs of electrons: nonpolar bonds: when electrons are shared equally between 2 atoms, polar bonds : electrons are more strongly attracted to one atom. These have a slight neg side and a slight pos side i: hydrogen bonds: attraction between opp charges. The oh is a functional group, making this compound a alcohol. Carbon skeletons vary a lot in shape, length, and pattern ii: proteins, proteins :most diverse biological molecule, amino acids: join together to form proteins.
