Question | Answer |
---|---|
Composed of several kinds of subatomic particles: protons, electrons, and neutrons | Atom |
The core of the atom. Contains positively charged protons and uncharged neutrons. | Nucleus |
The number of protons within the nucleus | Atomic Number |
The total of the protons and neutrons combined | Atomic Mass |
The limits in which electrons dart around constantly. Each one can hold 2 electrons | Orbitals |
Arrangement of orbitals based on its proximity to the nucleus. | Energy Levels |
Pure substances composed of only one atom. | Elements |
Substances whose molecules have more than one element in them. | Compounds |
Particles of matter that are composed of one or more atoms | Molecules |
A bond that is formed when one atom attaches to another by DONATING 1-2 electrons from its outermost level | Ionic Bond |
A bond that is formed when two atoms join by SHARING electrons. | Convalent Bonds |
A bond formed when oppositely charged ends of molecules are electrically attracted to each other. This is a weak attraction/bond. | Hydrogen Bonds |
Compounds that contain carbon-carbon (C-C) covalent bonds or carbon-hydrogen (C-H) covalent bonds, or both. | Organic Compound |
Compounds that typically DO NOT have carbon atoms in them and never have C-C or C-H bonds. | Inorganic Compound |
Compound of H2 and Oxygen | Water |
Compounds that produce |
