What are some chemical properties of the element silver?
some chemical properties areexplosive, flammable, and radioactive.
What factors determine an element's chemical properties?
There are specific factors that can contribute to a the properties of chemical elements. Some of these factors include the amount of valance electrons in the element.
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?

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 are some examples of chemical properties in helium?
Helium is chemically inert; it does not combine with any other element.
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.
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).

Element with the same chemical properties as nitrogen?
There is NOT such an element:All elements have an unique, some more, some less different set of chemical properties, though there are some metals resambling each other more than most of the nonmetals, like oxygen, nitrogen, chlorine, ... etc.
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.
