## What does the number of electrons in the outermost energy level of an element indicate?

valence electrons
The maximum number of electrons at a given energy level depends on its number of orbitals. There are at most two electrons per orbital. Electrons in the outermost energy level of an atom are called valence electrons. They determine many of the properties of an atom, including how reactive it is.

How are the number of electrons in the outer level and columns of the periodic table related?

The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. Every element in the first column (group one) has one electron in its outer shell. Every element in the second column (group two) has two electrons in the outer shell.

### How do you find the number of electrons in the outermost level?

So we can use the column or group of an element to determine the number of electrons in its outermost shell, sometimes referred to as valence electrons. Elements from the fourth column of the periodic table, like carbon, have four electrons in their outermost electron shell or four valence electrons.

How many electrons are in the highest occupied energy?

As you know, an element’s valence electrons are simply the electrons located on the outermost energy level, i.e. on the highest occupied energy level. Therefore, you can say that an element located in group #5″A”# has #5# electrons on its highest occupied energy level.

#### How to identify the number of electrons in the outermost shell?

So we can use the column or group of an element to determine the number of electrons in its outermost shell, sometimes referred to as valence electrons. Elements from the fourth column of the periodic table, like carbon, have four electrons in their outermost electron shell or four valence electrons. Fluorine is in the seventh column of the

Where are the electrons located on the periodic table?

Since each row of the periodic table represents an electron shell, elements on the left-hand side of the periodic table, like lithium, will have one electron in their outermost electron shell, whereas elements all the way on the right-hand side of the periodic table, like neon, will have full outer electron shells.

## How can we determine the number of electrons in an element?

So we can use the column or group of an element to determine the number of electrons in its outermost shell, sometimes referred to as valence electrons. Elements from the fourth column of the periodic table, like carbon, have four electrons in their outermost electron shell or four valence electrons.
