# How many electrons fit in the 3rd energy level of the electron cloud?

## How many electrons fit in the 3rd energy level of the electron cloud?

18 electrons
Note: The third energy level can actually hold up to 18 electrons, so it is not really filled when it has 8 electrons in it. But when the third level contains 8 electrons, the next 2 electrons go into the fourth level.

### How many electrons are in the 3rd electron orbital?

So the third shell can be considered to hold 8 or 18 electrons but in total the third shell can hold 18 electrons.

#### How many electrons are held on each level of the electron cloud?

The number of electrons on each level depends on which group the element belongs to. The valence electrons are the electrons in an atom’s outermost energy level in the electron cloud. level 1 holds 2 e~, level 2 holds 8, level 3 holds 8, and level 4 holds 18.

How many electrons can the 3 level hold?

Each orbital can hold up to two electrons, meaning that the 1s, 2s, 3s, 4s, and 5s can hold two electrons. The 2p,3p, 4p, and 5p can each hold six electrons because they have three orbitals.

How many electrons can the gizmo 3rd energy level hold?

Eight electrons fill level two, and 18 electrons fill level three. In general, each energy level must be full before electrons are placed on the next level.

## Which element has the highest number of electrons in the 3rd energy level?

sodium atom
In a sodium atom, the highest-energy principal energy level containing electrons is the third energy level, and that energy level contains one electron. The transition elements (or transition metals, for they are all metals) are those elements found in the short columns of the d block.

### Why is 3rd shell 8 or 18?

Each shell can contain only a fixed number of electrons, up to two electrons can hold the first shell, up to eight (2 + 6) electrons can hold the second shell, up to 18 (2 + 6 + 10) can hold the third shell and so on. …

#### How many electrons are in each level?

Each principal energy level can contain up to 2n2 electrons, where n is the number of the level. Thus, the first level can contain up to 2 electrons, 2(12) = 2; the second up to 8 electrons, 2(22) = 8; the third up to 18, 2(32) = 18; and so on.

What are the three parts of an electron cloud?

The current model of the atom is called the #3 Electron Cloud Model. In this model, the atom is made of three basic parts: protons, neutrons, and electrons. The protons are positively-charged particles, and the neutrons are particles that have no electrical charge.

How many electrons are held on each level?

The first energy level can hold up to 2 electrons, the second energy level can hold up to 8 electrons, the third energy level can hold up to 18 electrons, and the fourth energy level can hold up to 32 electrons. As mentioned above, each energy level or electron shell often contains multiple subshells.

## How many orbitals are in the N 3 level?

nine orbitals
There are nine orbitals in the n = 3 shell. There is one orbital in the 3s subshell and three orbitals in the 3p subshell. The n = 3 shell, however, also includes 3d orbitals.

### How many electrons are in energy level 3 in Sulfur?

So… for the element of SULFUR, you already know that the atomic number tells you the number of electrons. That means there are 16 electrons in a sulfur atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and six in shell three.

#### What is an electron cloud on the periodic table?

Electron cloud model is a model of an atom, in which the atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. Periodic Table Electron cloud model is a model of an atom, in which the atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons.

How many electrons does the third electron shell hold?

In this sense the third shell can hold 8 electrons. However in the fourth shell the 19th and 20th electrons go into the 4s2 not the third shell, but the next 10 electrons go into the 3d orbitals that are part of the third shell but shown on the fourth shell level. In this sense the third shell can hold a total of 18 electrons.

Why do we need an electron cloud model?

The electron cloud model says that we cannot know exactly where an electron is at any given time, but the electrons are more likely to be in specific areas. Electron cloud model defines the zone of probability describing the electron’s location, because of the uncertainty principle.

## Where are the electrons located in an atom?

Electrons were discovered by Sir John Joseph Thomson in 1897. Electrons are located in an electron cloud, which is the area surrounding the nucleus of the atom. The electron is only one member of a class of elementary particles, which forms an atom.
