Parts of the atom
positively charged particle in the nucleus of an atom
a subatomic particle that has no charge and that is located in the nucleus of an atom
negatively charged particle; located outside the atomic nucleus
the center of the atom which contains the protons and neutrons
a region in an atom where there is a high probability of finding electrons
any substance that cannot be broken down into simpler substances
the smallest unit of matter that has the characteristics of an element; consists of three main types of subatomic particles: protons neutrons and electrons.
one of two or more atoms with the same atomic number but with different numbers of neutrons
(chemistry) a substance formed by chemical union of two or more elements or ingredients in definite proportion by weight
the attractive force between two ions of opposite charge
atom that has a positive or negative charge
a chemical bond that involves sharing a pair of electrons between atoms in a molecule
the number of protons in the nucleus of an atom
the total number of protons and neutrons in the nucleus of an atom
two or more atoms held together by covalent bonds
Van der Waals
a slight attraction that develops between the oppositely charged regions of nearby molecules
molecules that have an unequal distribution of charges
noble gasses, have full outer shells, and DO NOT COMBINE
Those atoms with nearly full outer levels tend to acquire electrons to fill their orbitals.
Those atoms with a nearly empty outer level can find stability most easily by giving up an electron
