Most nitrogen on Earth is in nitrogen gas, but some nitrate minerals exist. Nitrogen makes up 2.5% of a typical human by weight. [citation needed] Phosphorus is 0.1% of the earth's crust, making it the 11th most abundant element. Phosphorus comprises 0.65 parts per million of soil and 15 to 60 parts per billion of seawater.
The next two elements, 119 and 120, should form an 8s series and be an alkali and alkaline earth metal respectively. The 8s electrons are expected to be relativistically stabilized, so that the trend toward higher reactivity down these groups will reverse and the elements will behave more like their period 5 homologs, rubidium and strontium .
Three precious metals found in Earth's interior. Aquelium is a bright green metal derived from the interior ocean, and terrelium is a vermilion metal found only in Atvatabar. When these two metals come in contact, they produce a harnessable form of energy called magnicity. Arenak Skylark: A synthetic metal made by Osnomians.
Einsteinium and fermium were discovered by a team of scientists led by Albert Ghiorso in 1952 while studying the composition of radioactive debris from the detonation of the first hydrogen bomb. [19] The isotopes synthesized were einsteinium-253, with a half-life of 20.5 days, and fermium-255 , with a half-life of about 20 hours.
Flerovium became the name of element 114; the final name proposed for element 116 was instead livermorium, [97] with moscovium later being proposed and accepted for element 115 instead. [ 98 ] Traditionally, the names of all noble gases end in "-on", with the exception of helium , which was not known to be a noble gas when discovered.
