What are some chemical properties of the element silver?
some chemical properties areexplosive, flammable, and radioactive.
What is Ac in the periodic table?
Actinium (Ac) is a chemical element with the atomic number 89, located in the actinide series of the periodic table. It is a radioactive metal that is primarily used in research and some specialized industrial applications.
When was francium first found?
Francium was discovered by Marguerite Perey in 1939 during a study on actinium-227: she observed an energy level possibly attributable to a new element. After some chemical experiments she was sure that the radiation is from a new chemical element, after this called francium.
Was francium an accidental find?
Francium was discovered by Marguerite Perey in 1939 during a study on actinium-227: she observed an energy level possibly attributable to a new element. After some chemical experiments she was sure that the radiation is from a new chemical element, after this called francium.
What country was francium first discovered?
Francium was discovered by Marguerite Perey (from France) in 1939 during a study on actinium-227: she observed an energy level possibly attributable to a new element. After some chemical experiments she was sure that the radiation is from a new chemical element, after this called francium.
What is the first actinide element?
ActinidesThis is a group of elements within the periodic table and are also known as the transuranics. The name refers to those elements with increasing atomic no. from actinium, which all have similar chemical properties, like the lanthanides. The first few members of the group are the naturally occurring elements actinium, thorium, proactinium and uranium. Beyond this elements have been made artificially by radioactive bombardment. These artificial elements are unstable, some have very short lifeimes and undergo spontaneous radioactive decay.
What are some examples of chemical properties in helium?
Helium is chemically inert; it does not combine with any other element.
What stands for the name of an element?
The name of an element usually represents its chemical identity and is based on characteristics such as color, origin, or properties. Elements are organized on the periodic table by their atomic number and chemical properties.
Boiling point melting and density are some of an elements nonreactive physicalor chemical properties?
Boiling point, melting point, and density are all physical properties of an element. They determine the state of the element.
What factors determine an element's chemical properties?
An element's chemical properties are primarily determined by its electron configuration, which dictates how it interacts with other atoms to form compounds. Other factors include the number of protons in the nucleus, which affects its reactivity and chemical behavior, as well as its position on the periodic table, which can provide insights into its properties based on trends within a group or period.
What are some elements that react with actinium?
Actinium is a highly reactive element that can react with air, water, and acids to form compounds. It can react with oxygen to form actinium oxide, with nitrogen to form actinium nitride, and with dilute acids to form various salts.
How many chemical properties does isotopes have?
All the isotopes of a chemical element are identical; some differences exist for light elements (ex. H or D).
