ChemicAl Bonding Flashcards
Chemical combining
Combining of atoms of elements to form new substances.
Valence electron
Electron in the outermost energy level of an Atom.
Ion
An atom that has become charged because it’s number of protons is different than its number of electrons
Covalent bonding
Bonding that involves the sharing of electrons.
Electron dot diagram
Diagram that uses the chemical symbol for an element surrounded by a series of dots to represent the electron sharing that takes place in a covalent bond.
Diatomic element
Element whose atoms can form covalent bonds with another atom of the same element.
Molecule
Combination of Atoms formed by a covalent bond
Polyatomic ion
Group of covalently bonded atoms that carries a charge and acts as a unit
Metallic bond
Bond formed by atoms of metals in which the outer outer electrons of Atoms form a common electron cloud
Oxidation number
Number of electrons in atoms Gains uses or shares when it forms chemical bonds
Chemical reaction
Process in which substances undergo physical and chemical changes that result in the formation of new substances with different properties
Reactant
Substance that enters into a chemical reaction
Product
Substance produced by a chemical reaction
Chemical equation
Expression in which symbols formulas in numbers are used to represent a chemical reaction
Exothermic
chemical reaction in which heat is released
