Phosphorus

Phosphorus has atomic number 15, and is in group 5 and period 3 of the Periodic Table. It is in period 3, because it has orbits at 3 energy levels. There are 2 electrons at the first energy level, and 8 at the second energy level. There are 15 electrons in total, there must be 5 electrons at the third energy level. Phophorus is in group 15, it has 5 electrons in its outer shell, 3s23p3. When it forms chemical compounds it can share electrons to form covalent bonds or gain 3 electrons to form the P3- phosphide. Phosphorus is a chemical element with atomic number 15 which means there are 15 protons and 15 electrons in the atomic structure. The atomic number of each element increases by one, reading from left to right. Block Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f).

Electron Configuration Notation:
-shows the arrangment of electrons around the nucleus of an atom.
- helps chemist understanding how elements form chemical bonds.
- can be written using the period table or an electron configuration chart.

In order to write the Phosphorus electron configuration we first need to know the number of electrons for the P atom (there are 15 electrons). When we write the configuration we'll put all 15 electrons in orbitals around the nucleus of the Phosphorus atom.

How Many Electrons Does Phosphorus

In writing the electron configuration for Phosphorus the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Phosphorous go in the 2s orbital. The next six electrons will go in the 2p orbital. 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 three electrons. Therefore the Phosphorus electron configuration will be 1s22s22p63s23p3.

The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds.
