Is a bronze an element compound or mixture?
Bronze is a mixture of two elements, copper and tin.Is bronze a element or not?
Bronze is a metal alloy that primarily contains copper and 12% tin. Other elements—such as aluminum, arsenic, manganese, phosphorus, and silicon—are also added to yield different properties. These mixtures form some of the common bronze alloys, including: Leaded bronze.Is bronze a mixture and not compound?
Brass and bronze are mixtures.- Bronze is an alloy consisting primarily of copper, commonly with about 12–12.5% tin and often with the addition of other metals (including aluminium, manganese, nickel, or zinc) and sometimes non-metals, such as phosphorus, or metalloids such as arsenic or silicon.

joined together by chemical bonds.In the animation above, water (H20) is a
compound made of Hydrogen andOxygen.
The red compound is
composed of nickel (Ni) (silver)
carbon (C) (black)
hydrogen (H) (white)
oxygen (O) (red)
nitrogen (N) (blue)
CHEMICAL COMPOUNDS are
composed of atoms and so can be decomposed to those atoms.A molecule consists of two or more atoms of
the same element, or different elements, that are chemically bound together.In the animation above, two nitrogen atoms
(N + N = N2) make one Nitrogen molecule .Chemical Bonds
yMolecules are held together by bonds yIonic bonds yCovalent bonds IONS yIONS are atoms or groups of atoms with a positive or negative charge. . yTo tell the difference between an atom and an ion, look to see if there is a charge in the superscript! Examples:Na+ Ca+2 I- O-2
