nonpolar covalent bond - ✔️✔️equal sharing of electrons
properties of water - ✔️✔️high heat capacity, polar solvent, reactivity, cushioning
atomic structure - ✔️✔️nucleus, electron shell
ionic bond - ✔️✔️involve the transfer of one or more electrons from one atom to
another; results in atoms being charged
Matter - ✔️✔️Anything that takes up space and has mass
elements - ✔️✔️substances that cannot be broken down by ordinary chemical means
atoms - ✔️✔️smallest piece of an element; smallest unit of matter
major elements of the body - ✔️✔️oxygen, carbon, hydrogen, nitrogen
atomic number - ✔️✔️number of protons
mass number - ✔️✔️number of protons and neutrons
isotope - ✔️✔️atoms with different numbers of neutrons
compound - ✔️✔️two or more different kinds of atoms or elements sharing electrons
molecules - ✔️✔️compound containing only one type of atom or element
solvent - ✔️✔️water
solute - ✔️✔️what is dissolved in water
octet rule - ✔️✔️except for the first shell, atoms try to have 8 electrons in their valance
shell
anions - ✔️✔️gain electrons, makes them negatively charged
cations - ✔️✔️lose electrons, makes them positively charged
