## What is the highest energy level in silicon?

third energy level
The Aufbau Principle states that electrons fill empty orbitals in order of increasing energy levels. In your case, the highest energy level that holds electrons in a silicon atom will be the third energy level.

### Which atomic orbital has the highest energy?

s orbitals
For a given atom, the s orbitals also become higher in energy as n increases because of their increased distance from the nucleus.

What is the highest energy level orbital?

Electrons that are in the highest energy level are called valence electrons. Within each energy level is a volume of space where specific electrons are likely to be located. These spaces, called orbitals, are of different shapes, denoted by a letter (s, p, d, f, g).

What is the orbital for silicon?

Since 1s can only hold two electrons the next 2 electrons for Silicon go in the 2s orbital. The nex six electrons will go in the 2p orbital. The p orbital can hold up to six electrons.

## Does SI have 4 energy levels?

Silicon is composed of 14 electrons, 14 protons, and (in most cases) 14 neutrons. In its ground state, silicon has two electrons in the n = 1 energy level, eight in the n = 2 energy level, and four in the n = 3 energy level, as shown on the energy diagram to the left.

### Does germanium have 4 energy levels?

Germanium is in the same family with the elements carbon and silicon. They all have four electrons in their outer shell. The orbital structure for germanium is 2-8-18-4.

Which orbital is lowest in energy?

1s orbital
At the lowest energy level, the one closest to the atomic center, there is a single 1s orbital that can hold 2 electrons. At the next energy level, there are four orbitals; a 2s, 2p1, 2p2, and a 2p3. Each of these orbitals can hold 2 electrons, so a total of 8 electrons can be found at this level of energy.

Does 3s or 4s have more energy?

We say that the 4s orbitals have a lower energy than the 3d, and so the 4s orbitals are filled first. The electrons lost first will come from the highest energy level, furthest from the influence of the nucleus. So the 4s orbital must have a higher energy than the 3d orbitals.

## Why does P have 3 orbitals?

Since electrons all have the same charge, they stay as far away as possible because of repulsion. So, if there are open orbitals in the same energy level, the electrons will fill each orbital singly before filling the orbital with two electrons. For example, the 2p shell has three p orbitals.

### What is the charge of silicon?

4+
Table of Common Element Charges

Number Element Charge
14 silicon 4+, 4-
15 phosphorus 5+, 3+, 3-
16 sulfur 2-, 2+, 4+, 6+
17 chlorine 1-

Which energy level has the highest energy?

What Are Energy Levels?

• Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found.
• Q: In the atomic model Figure above, where would you find electrons that have the most energy?
• A: Electrons with the most energy would be found in energy level IV.

Where do the electrons go in a silicon atom?

When we write the configuration we’ll put all 14 electrons in orbitals around the nucleus of the Silicon atom. In writing the electron configuration for Silicon the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Silicon go in the 2s orbital.

## What is the atomic number of a silicon atom?

The atomic number of silicon is 14 i.e. 14 protons. The number of protons in the nucleus of an atom is called atomic number. Silicon atom has 14 electrons (two electrons in first orbit, eight electrons in second orbit and 4 electrons in the outermost orbit).

### How many electrons can a p orbital hold?

The p orbital can hold up to six electrons. We’ll put six in the 2p orbital and then put the next two electrons in the 3s. Since the 3s if now full we’ll move to the 3p where we’ll place the remaining two electrons. Therefore the Silicon electron configuration will be 1s 2 2s 2 2p 6 3s 2 3p 2.

How many electrons does germanium have in its orbit?

Germanium has 32 electrons (2 electrons in first orbit, 8 electrons in second orbit, 18 electrons in third orbit and 4 electrons in the outermost orbit.
