## How do you write a subshell electron configuration?

Notation

1. The electron configuration of an atom is written with the help of subshell labels.
2. These labels contain the shell number (given by the principal quantum number) the subshell name (given by the azimuthal quantum number) and the total number of electrons in the subshell in superscript.

## Does iron have 2 or 8 valence electrons?

-From the electronic configuration of the iron atom we come to know that the number of electrons present in the outermost shell i.e. 3 d orbital and 4 s orbital are 8 electrons. Thus the total number of valence electrons present in iron is eight.

## How many electrons does an Fe atom have in its 3d subshell quizlet?

Iron is 4s^2 3d^6 so it will have 4 unpaired 3d electrons.

## What is the composition of iron?

Most of the iron in the crust is combined with various other elements to form many iron minerals. An important class is the iron oxide minerals such as hematite (Fe2O3) magnetite (Fe3O4) and siderite (FeCO3) which are the major ores of iron.

## What elements make up iron?

Iron is primarily obtained from the minerals hematite (Fe2O3) and magnetite (Fe3O4). The minerals taconite limonite (FeO(OH)·nH2O) and siderite (FeCO3) are other important sources. Huge amounts of iron are used to make steel an alloy of iron and carbon.

## What is the number of protons and electrons in Fe 3?

Electron “cloud” of orbitals Difference of number of electrons from number of protons defines the charge on an atom. For example among atoms of iron all with 26 protons Fe2+ has 24 electrons and Fe3+ has 23 electrons whereas elemental (uncharged) Fe has 26 electrons. the mass of an atom is outside the nucleus.
