Element 118 on the periodic table, oganesson, has one hundred and eighteen protons and electrons. A synthetic element, aganesson can only be found on Earth in the particle accelerators used to produce it. It has only one known radioisotope which has a half-life of around 890 microseconds.

On the periodic table, oganesson technically falls into the p-block transactinide elements as a member of the noble gases, however not enough experiments have been carried out on the element to confirm that it follows the trends of the elements that come before it.

Element 117 on the periodic table, tennessine, has one hundred and seventeen protons and electrons. A synthetic element, tennessine can only be found on Earth in the particle accelerators used to produce it. It has only two known radioisotopes, the most stable of which has a half-life of around fifty milliseconds.

On the periodic table, tennessine technically falls into the p-block transactinide elements as a member of the post-transition metals and of the halogen group, however not enough experiments have been carried out on the element to confirm that it follows the trends of the elements that come before it.

Element 116 on the periodic table, livermorium has one hundred and sixteen protons and electrons. A synthetic element, livermorium can only be found on Earth in the particle accelerators used to produce it. It has less than five known radioisotopes, the most stable of which has a half-life of around fifty milliseconds.

On the periodic table, livermorium technically falls into the post transition metals as a member of the chalcogen group, however not enough experiments have been carried out on the element to confirm that it follows the trends of the elements that come before it.

Element 115 on the periodic table, moscovium, has one hundred and fifteen protons and electrons. A synthetic element, moscovium can only be found on Earth in the particle accelerators used to produce it. It has just under five known radioisotopes, the most stable of which has a half-life of around 220 milliseconds.

On the periodic table, moscovium technically falls into the p-block transactinide elements as a member of the post-transition metals, however not enough experiments have been carried out on the element to confirm that it follows the trends of the elements that come before it.

Flerovium is the one hundred and fourteenth element on the periodic table, giving it one hundred and fourteen protons and electrons. A synthetic element, flerovium can only be found on Earth in the particle accelerators used to produce it. It has around five known radioisotopes, the most stable of which has a half-life of around two and a half seconds.

On the periodic table, it is often classified as a post transition metal. These metals are generally soft, with poor mechanical strength and low melting points. Metals typically have good thermal and electrical conductivity and usually form cations rather than anions.

It has been predicted that flerovium could be a gaseous metal, with a low boiling point, as well as perhaps a noble metal. 

Element 113 on the periodic table, nihonium, has one hundred and thirteen protons and electrons. A synthetic element, nihonium can only be found on Earth in the particle accelerators used to produce it. It has just over five known radioisotopes, the most stable of which has a half-life of around twenty seconds.

On the periodic table, nihonium technically falls into the p-block transactinide elements, however not enough experiments have been carried out on the element to confirm that it follows the trends of the elements that come before it.

Element 112 on the periodic table, copernicium has one hundred and twelve protons and electrons. A synthetic element, copernicium can only be found on Earth in the particle accelerators used to produce it. It has less than ten known radioisotopes, the most stable of which has a half-life of around thirty seconds.

On the periodic table, the element is most often characterized as a transition metal. Given the sheer number of transition metals it is difficult to define any definite characteristics but, generally, transition metals are paramagnetic with more than one oxidation states. Also, metals typically (though not always) have high electrical conductivity as well as high density and high melting and boiling points.

Element 111 on the periodic table, roentgenium has one hundred and eleven protons and electrons. A synthetic element, roentgenium can only be found on Earth in the particle accelerators used to produce it. It has less than ten known radioisotopes, the most stable of which has a half-life of around two minutes.

On the periodic table, roentgenium technically falls into the d-block transition metals, however not enough experiments have been carried out on the element to confirm that it follows the trends of the elements that come before it.
