What would element 119 look like?
Element 119 is expected to be a typical alkali metal with a +1 oxidation state. The energetic properties of its valence electron, the 8s electron, suggest that its first ionization potential will be higher than the oxidation potential predicted by simple extrapolation, so that the…
What is the 83th element of the periodic table?
Bismuth
Bismuth is a chemical element with symbol Bi and atomic number 83. Classified as a post-transition metal, Bismuth is a solid at room temperature.

What type of element is bismuth?
post-transition metal
Bismuth, element 83 on the periodic table of elements, is a post-transition metal, according to Los Alamos National Laboratory. (Different versions of the periodic table represent it as a transition metal.)
What elements does bismuth bond with?
At red heat, bismuth reacts with steam, but it is not affected by cold, air-free water; it combines directly with sulfur and with the halogens (fluorine, chlorine, bromine, iodine).
What was the first artificially produced element?
technetium
In 1937, technetium (specifically the technetium-97 isotope) became the first predominantly artificial element to be produced, hence its name (from the Greek τεχνητός, meaning “Craft, Art or Artificial”, + -ium).
What was the first artificially produced chemical element?
technetium (Tc), chemical element, synthetic radioactive metal of Group 7 (VIIb) of the periodic table, the first element to be artificially produced.

What are some elements that occur naturally but are not pure?
Elements that occur naturally, yet not in native form, include the alkali metals, alkaline earth, and rare earth elements. These elements are found bound in chemical compounds, not in pure form. Helmenstine, Anne Marie, Ph.D.
What is the periodic table of elements in order?
Periodic Table of Elements. The periodic table is a tabular arrangement of the chemical elements. It is organized in order of increasing atomic number. There is a recurring pattern called the “periodic law” in their properties, in which elements in the same column (group) have similar properties.
What causes the initial unevenness in the periodic table of elements?
The initial unevenness occurs because the alkali and alkaline earth metals fall on the left as a tall block followed by a shallower ten element-wide block containing the transition metals. This is followed on the right edge by another taller block, which is six elements wide and contains a mixture of metals, semi-metals and non-metals.
What is the lightest element on the periodic table?
With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75\% of all baryonic mass.
