The number of protons determine which element an atom is and normally the number of electrons is equal to it. Strip an electron off an iron atom and you have an ionised iron atom.

How can one determine the electron configuration of an element?

To determine the electron configuration of an element, one can use the periodic table to identify the element's atomic number, which indicates the number of protons in the nucleus. Then, electrons are distributed into energy levels and sublevels according to specific rules, such as the Aufbau principle and the Pauli exclusion principle. This process helps to determine the arrangement of electrons in an atom's orbitals.


How do you know how many unpaired electrons are in an element?

You can determine the number of unpaired electrons in an element by examining its electron configuration. Unpaired electrons are found in the outermost energy level, and you can count them by looking for half-filled or singly occupied orbitals in the notation of the element.


Is oxygen an electron donating or withdrawing element?

Oxygen is an electron withdrawing element.


What is the name given to the electron in the highest occupied energy level?

The electron in the highest occupied energy level is known as the valence electron. These electrons are involved in the formation of chemical bonds and determine the element's chemical properties.


How many electron shells does the element titanium have?

This is a chemical element. You can find the how many electron in a single atom by using a periodic table.


What element has no electron affinity?

Helium has no electron affinity.


How many elements does the outer electron have?

An electron is not an element.


What is the significance of the period in the periodic table?

The period in the periodic table represents the number of energy levels or electron shells an element's atoms have. It helps determine the element's properties and how it interacts with other elements.

The element with this electron configuration is manganese (Mn), which has 25 electrons.


Which element has a single electron in the 2p sublevel?

The element that has a single electron in the 2p sublevel is boron. The electron configuration of Boron is 1s22s22p1.


What element has electron configuration 1s22s23p1?

The element with electron configuration 1s22s23p1 is phosphorus, which has an atomic number of 15.


How can you determine the number of valence electrons for an element on the periodic table?

To determine the number of valence electrons for an element on the periodic table, you look at the group number of the element. The group number tells you how many valence electrons the element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
