Question

what are 2 chemical properties of iron?

Answer 1

Answer:

Two chemical properties of iron are the atomic number is $26$ and the chemical formula is $Fe$.

Explanation:

Iron is a metal of many important features. Its atomic number is $26$ and the chemical formula is $Fe$. It can react with oxygen and forms oxides that are known as rust. It is non-toxic in nature. It can react with steam and hot water and produces hydrogen gas. It is soluble in acids.

Answer 2

Iron

• The silver-gray metal iron is lustrous, ductile, and malleable (group VIII of the periodic table).
• There are four different crystalline forms known to exist.
• Wet air rusts iron, whereas dry air does not. In weak acids, it dissolves quickly.
• The bivalent iron (II), or ferrous, compounds, and the trivalent iron (III), or ferric, compounds, are both chemically active.

Iron - the element –

• an electrical configuration of [Ar]4s23d6 and 14 recognised isotopes.
• Iron is the fourth most prevalent metal in the Earth's crust and an important chemical element in the human body.
• It is a transition metal that is found in the first transition series of the periodic table.
• It is usually found in the oxidation states +2 and +3. Ferrous refers to iron (II) compounds, whereas ferric refers to iron (III).
• The hue of iron (II) compounds is bright green, whereas that of iron (III) compounds is orange/brown.
• It can also be found in potassium ferrate, which has a higher oxidation state of +6. (K2FeO4).
