A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
Rubidium bromide is an inorganic compound with the chemical formula Rb Br. It is a salt of hydrogen bromide. It consists of bromide anions Br − and rubidium cations Rb +. It has a NaCl crystal structure, with a lattice constant of 685 picometres. [1] There are several methods for synthesising rubidium bromide.
Rubidium is a chemical element; it has symbol Rb and atomic number 37. It is a very soft, whitish-grey solid in the alkali metal group, similar to potassium and caesium. [9] Rubidium is the first alkali metal in the group to have a density higher than water.
The radius increases sharply between the noble gas at the end of each period and the alkali metal at the beginning of the next period. These trends of the atomic radii (and of various other chemical and physical properties of the elements) can be explained by the electron shell theory of the atom; they provided important evidence for the ...

A bromide ion is the negatively charged form (Br −) of the element bromine, a member of the halogens group on the periodic table. Most bromides are colorless. Most bromides are colorless. Bromides have many practical roles, being found in anticonvulsants, flame-retardant materials, and cell stains. [ 3 ]
