Is bronze made of one element?
no it is not. you can find all the known elements on a periodic table of elements online or in a science textbook
Why are periods 6 and 7 on the periodic table split up?
NO because it is having same elements that are not yet been studied rightly and there positions may change if actual properties are known and seventh period is incomplete and contains ninteen elements (Z=87 to 105).....The elements after actiniun (Z=89 to 91) are called actinides
Where on the periodic table do the most man-made elements appear?
Most man-made elements appear in the lower rows of the periodic table, specifically in the transuranium (after uranium) region. These elements have atomic numbers higher than 92 and are typically synthesized in laboratories using particle accelerators or nuclear reactors.

What group of elements in the periodic table is made up of elements that are gases at room temperature?
The elements in column 18 of a wide form periodic table or Column VIII of a narrow form periodic table, commonly called the noble gases. Also, both elements in the first period, the elements in groups 15, 16, and 17 of the second period, and the element in group 17 of the third period.
Which period table group are made up of only gases?
The first period or row contains only elements that are gases at standard temperature and pressure.
How many elements have scientist made in the laboratory?
Scientists have made over 30 elements in the laboratory, known as synthetic elements. These elements are typically created by nuclear reactions and are usually unstable and decay quickly. Examples include elements like neptunium, americium, and tennessine.
How many are man made elements of the 118 known elements?
The 26 transuranic elements (elements with atomic numbers higher than 92) are man-made. Some lists also count technetium (element 43) as man-made as well. --------------- Now (January 2013) 97 chemical elements are considered as natural and 21 as man made.
Metal compounds made of two or more metallic elements are known as?
Metal compounds made of two or more metallic elements are usually called ALLOYS. However, there are true compounds and these are often known simply as inter-metallic compounds.
