Answer:
any of the set of metallic elements occupying a central block (Groups IVB–VIII, IB, and IIB, or 4–12) in the periodic table, e.g., iron, manganese, chromium, and copper. Chemically they show variable valence and a strong tendency to form coordination compounds, and many of their compounds are colored.
Explanation:
Answer:
The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons. ... The value of the radius may depend on the atom's state and context.
Explanation:
They all have a certain amount of protons electrons and neutrons.
Answer:
The pattern of decay emission is visualized on X-ray film by auto-radiography.
Explanation:
The image on the x-ray are auto-radiography or the nuclear emission that has been produced as a result of the decay emission because of the gamma particles or the beta particles which comes from a radioactive substance. These auto-radiography are available as the digital image as a result of recent development of gas detectors or because of the rare earth phosphor imaging system. Some of the can be studied microscopically for silver granules this method is called as micro- auto-radiography.
