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 is the 18th most abundant element in seawater. [15]: 371 Because of its large ionic radius, rubidium is one of the "incompatible elements". [34] During magma crystallization, rubidium is concentrated together with its heavier analogue caesium in the liquid phase and crystallizes last.
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 ]
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.

Transactinide elements – Elements after the actinides (atomic number greater than 103). Transplutonium elements – Elements with atomic number greater than 94. Transuranium elements – Elements with atomic number greater than 92. Valve metal - a metal which, in an electrolytic cell, passes current in only one direction.
Silver bromide (AgBr). Nearly all elements in the periodic table form binary bromides. The exceptions are decidedly in the minority and stem in each case from one of three causes: extreme inertness and reluctance to participate in chemical reactions (the noble gases, with the exception of xenon in the very unstable XeBr 2; extreme nuclear instability hampering chemical investigation before ...
