CBSE Class 10 Chemistry notes"},"content":{"rendered":"

In Class 10 Chemistry, there is a topic named electronic configuration of iron, which is essential to identify the characteristics and properties of iron as an atom. Iron is an element present in the modern periodic table with the symbol Fe. Its atomic number is 26. It belongs to the first transition series. Iron can be seen in the 8<\/span>th<\/span> group of the periodic table.<\/span><\/p>\n

The mass of one mole of iron is approximately 55 grams. Iron and oxygen are considered among the most common materials on earth due to their popularity and importance. It can be found in the inner and outer core of the earth. Furthermore, iron can be described as the 2<\/span>nd<\/span> most abundant element ever that existed inside the earth’s crust. The presence of iron can be seen throughout the planet.<\/span><\/p>\n

In this informative article, let us look at the concepts of iron and its electronic configurations while having a brief understanding of all the related concepts.<\/span><\/p>\n
