What is identification element?
What is identification element?
Explanation: The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes. Number of neutrons can be altered to create isotopes.
What is element 123 called?
Murinite (symbol Mu) is a chemical element, atomic number 123 on the periodic table.
What is the average atomic mass of Centium 200 Centium 203 and Centium 209?
Answer Expert Verified Average atomic mass = [200 + 203 + 209] / 3 = 612 /3 = 204. Thus, the average atomic mass of the element is 204.
What is francium used for?
Francium has been used in the field of research, chemistry and also in the atomic structure. It is used for diagnostics for curing cancers. It is also used in many spectroscopic experiments. Francium is a highly radioactive metal, and since it exhibits a short half-life, it does not have more impact on the environment.
How do I know my element name?
The names of elements are determined from their position on the Periodic Table. In the modern Periodic Table, the elements are listed in order by increasing atomic number. The atomic number is the number of protons in the nucleus of an atom of a particular element.
What are three ways to identify an element?
Flame tests, atomic spectra, and spectroscopy can be used to identify some elements.
How is the chemical symbol of an element determined?
Answer: The number of protons defines what element it is and also determines the chemical behavior of the element. Atomic symbol: The atomic symbol (or element symbol) is an abbreviation chosen to represent an element (“C” for carbon, “H” for hydrogen and “O” for oxygen, etc.)
What is the difference between chlorine 35 and chlorine 37?
Chlorine-35 and chlorine-37 are both isotopes of the element chlorine. An atom of chlorine-35 contains 18 neutrons (17 protons + 18 neutrons = 35 particles in the nucleus) while an atom of chlorine-37 contains 20 neutrons (17 protons + 20 neutrons = 37 particles in the nucleus).
Is francium used in nuclear bombs?
Since the metal is alkaline, it is believed to react violently with water, producing francium hydroxide and hydrogen, and a massive amount of heat. So far, no such experiment has been conducted to prove it even though many false claims have been made showing francium exploding like a bomb when dropped in the ocean.
Is francium a bomb?
Because the alkali metals react viciously with water, a huge explosion will result when the two substances are combined, especially with the heavier alkalis like cesium and francium. This is the explosion necessary for our francium Bomb. First off, francium is highly rare.
What are the properties of the element cerium?
