Test passes if there are two columns of widths: 1) max-intrinsic and 2) the rest left.
H2 elements shall span both columns. Content in first column shall be right aligned and ended with ':'.
Transition metals
- Scandium
- is a chemical element with symbol Sc and atomic number 21.
A silvery-white metallic transition metal, it has historically been sometimes classified as a rare earth element,
together with yttrium and the lanthanoids.
It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia.
- Titanium
- is a chemical element with the symbol Ti and atomic number 22.
It has a low density and is a strong, lustrous, corrosion-resistant (including sea water, aqua regia and chlorine)
transition metal with a silver color.
- Vanadium
- is a chemical element with the symbol V and atomic number 23.
It is a hard, silvery gray, ductile and malleable transition metal.
The formation of an oxide layer stabilizes the metal against oxidation.
The element is found only in chemically combined form in nature.
Halogens
- Fluorine
- is the chemical element with atomic number 9, represented by the symbol F.
It is the lightest element of the halogen column of the periodic table and has a single stable isotope, fluorine-19.
At standard pressure and temperature, fluorine is a pale yellow gas composed of diatomic molecules, F2.
- Chlorine
- is the chemical element with atomic number 17 and symbol Cl.
It is the second lightest halogen, found in the periodic table in group 17.
The element forms diatomic molecules under standard conditions, called dichlorine.
