Fill in the blank with the correct name or term. The table below was developed by _______________ and is based on a relationship called the law of octaves. According to this law, the properties of the elements repeated every eight elements. The law of octaves did not work for all the known elements and was not generally accepted.

• John Newlands

• Dmitri Mendeleev

• Henry Moseley

• Lothar Meyer

The first periodic table is mostly credited to _______________. In his table, the elements were arranged according to increasing _______________. One important result of this table was that the existence and properties of undiscovered elements could be predicted.

• The first periodic table is mostly credited to Dmitri Mendeleev. In his table, the elements were arranged according to increasing atomic mass.

• The first periodic table is mostly credited to Antoine Lavoisier. In his table, the elements were arranged according to increasing atomic number.

• The first periodic table is mostly credited to John Dalton. In his table, the elements were arranged according to increasing atomic weight.

• The first periodic table is mostly credited to Henry Moseley. In his table, the elements were arranged according to increasing atomic number.

The elements in the modern periodic table are arranged according to increasing _______________, as a result of the work of _______________.

• atomic number; Henry Moseley

• atomic mass; Henry Moseley

• atomic weight; John Dalton

• atomic volume; Niels Bohr

This arrangement is based on number of _______________ in the nucleus of an atom of the element.

• protons

• neutrons

• electrons

• atoms

The modern form of the periodic table results in the _______________, which states that when elements are arranged according to increasing atomic number, there is a periodic repetition of their chemical and physical properties.
