Is plutonium man made?
Plutonium is considered a man-made element, although scientists have found trace amounts of naturally occurring plutonium produced under highly unusual geologic circumstances. The most common radioisotopes. For example, uranium has thirty-seven different isotopes, including uranium-235 and uranium-238.
Are Br and Kr similar?
They are the same because each has the same atomic number. They are different because each has a different atomic number.
What are the group B elements?
They are located in the middle of the periodic table between Group IIA and Group IIIA. They provide transition between the “base formers” on the left and “acid formers” on the right. The most common transition metals include chromium, manganese, copper, iron, coblat, zinc, silver, mercury and gold.
What is the B group?
Boron group element, any of the six chemical elements constituting Group 13 (IIIa) of the periodic table. The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and nihonium (Nh).
What is the difference between group A and group B metals?
What is the basic difference between group A and group B elements from the electronic configuration point of view. In group A elements, the added electrons goes to the outermost shell. In group B, the additional electron goes to penultimate shell.
What are class A and class B metals?
Class A metals are metals that form hard acids. Hard acids are acids with relatively ionic bonds. Class B metals are metals that form soft acids. Soft acids are acids with relatively covalent bonds. These metals, such as lead, gold, palladium, platinum, mercury, and rhodium, would rather bond with iodine than fluorine.
