Nuclear Chemistry
The mass of an atom, including its protons, neutrons, and electrons. It is usually expressed in atomic mass units (amu).
Atomic mass
A chart containing all of the elements arranged into rows and columns, based on recurring trends of their properties.
Periodic Table
Sometimes referred to as a group, it is a vertical column in the periodic table.
Family
the degree of attraction an atom has for additional electrons. It helps determine what type of bond an atom will form.
electronegativity
a method of expressing a chemical reaction
chemical equation
The number of protons in an atom. Each element has a unique atomic number, that stays constant, which allows it to be used to identify an atom.
The physical and chemical properties of elements occur in a systematic manner that correlates with their atomic number.
Periodic Law
Highly reactive chemical elements that form group 1 (IA), that each have one valance electron.
alkali metals
a type of bond that involves the transfer of electrons from one atom to another.
ionic bond
a reaction in which two or more substances are combined to form a single product.
combination reaction
Elements whose atoms have the same number of protons, but different numbers of neutrons.
Isotopes
Describes how an atom's electrons are arranged.
Electron configuration
A series of elements that forms group 2 (IIA), that each have two valence electrons.
alkaline earth metals
also known as Lewis dot structures, they are diagrams that show the valence electrons of an element. they are made up of the elements symbol surrounded by dots representing its electrons, and can be used to show bonds between atoms.
Electron Dot Structure
a reaction that breaks one substance into two or more products
decomposition reaction
When particles and rays are emitted from a nuclei.
Radioactivity
The electrons that make up the outermost energy level, and that play a key role in determining how atoms react with each other.
valence electrons
A homogeneous mixture of multiple metallic elements.
alloys
substances that dissociate to form free ions, making the solution conductive, when dissolved.
electrolyte
a reaction in which one element from a compound is replaced by another element.
single replacement reaction
A particle identical to a helium nucleus, composed of two protons and two neutrons bound together.
Alpha particle
A nuclear reaction in which multiple atomic nuclei are combined to form a larger one.
nuclear fusion
A group of strong metals that exhibit similar characteristics, and can be found in groups 3-12 (IB-VIIIB) of the periodic table.
transition elements
a sharing of electrons between two elements that are non metals.
covalent bond
solid material formed during a chemical reaction.
