Chemical Bonds
How many types of bonds exists?
3
What is a proton
A positive charged particle
Compiled a list of all elements that were known at the time. Contained 33 elements organized in four categories (gases, metals, nonmetals and earths).
Antoine Lavoisier
The compound of two monoatomic ions
Binary ionic compound
How many elements are in the periodic table?
118
Covalent bond
What is an electron
A negative charged particle
Noticed that elemental properties repeated every eighth element when elements were listed by relative atomic mass.
John Newlands
Are orbiting around the nucleus of an atom
Electrons
How many blocks are in the periodic table?
4
Occurs when a group of metal atoms shares a cloud of valence electrons
Metallic Bond
The short version of the electron configuration
Noble gas notation
He left gaps for undiscovered elements and predicted their properties.
Dmitri Mendeleev
An ion with a positive charge, elements in groups 1A, 2A, 3A and 4A.
Cation
Which group corresponds to the Noble Gases?
8 or 18
It is necessary for the attraction between atoms in an ionic bond.
A negative and a positive charge.
Electrons located in the outter shell of an atom
Valence electrons
Discovered that atoms of each element contain a unique number of protons in their nuclei.
Henry Moseley
An ion with a negative charge, elements in groups 5A, 6A and 7A.
Anion
How many periods are in the periodic table?
7
Main characteristic of an Ionic Bond
Atoms gains or lose electrons
Synonym of electron shells
Energy Level
He invented the law of octaves
John Newlands
A covalent bonded set of two or more ions
Polyatomic ion
Year of the invention of the periodic table as we know it now
1869
