Periodic Table

Atoms & P Table

Atomic Number Number of protons in the nucleus of an atom, also know as the positive charge (above the abbreviation) Identifier
Atomic Weight The average weight of an atom in an element (under the name of the Element) protons added to the neutrons.
Electron Affinity Measure of the energy change when an electron is added to a neutral atom to form a negative ion. The neutral Atoms likelihood of gaining an electron, a group of electrons around a nucleus.
Electronegativity Measure of the likelihood of an atom to attract a bonding pair of electrons.
Atomic Radius The measure from the nucleus of the atom to the boundary of the surrounding cloud of electrons
Metallic Character The name given to a set of chemical properties associated with elements that are metals (shiny)
Types of Chemical Bonds Formed Threes types are Ionic reactivity between two oppositely charged ions, Covalent sharing electron pairs between atoms, also metallic bonds.
Valence Electrons An electron that associated with and atom and which helps to from chemical bonds. Also electrons in the outer most energy level
Ionization Energy The energy needed to remove one or more electrons from a neutral atom to form a positively charged ion.
Melting Point The temperature where a solid will turn into a liquid.
Number of Bonds Formed The number of bonds formed by the sharing of a pair of electrons by two atoms.
Metallic Bond Metallic Bonds- formed by the valence electrons moving freely through the metal lattice.
