Construction of an Atom Notes

Heisenberg Uncertainty Principle States that we cannot know the position and the speed of a moving object simultaneously

Due to this, we will discuss where it is LIKELY that we will find an electron Due to this, we will discuss where it is LIKELY that we will find an electron

Important fact about electrons… Electrons are LAZY! They will use as little energy as possible. Electrons are LAZY! They will use as little energy as possible.

Around the Nucleus Around the nucleus there are Principal Energy Levels. The Principal Energy Levels are made up of Sublevels. The Sublevels are made up of Orbitals. The Orbitals hold the electrons.

Principal Energy Levels We call them “n” We call them “n” 1 st energy level is n=1 1 st energy level is n=1 2 nd energy level is n=2 2 nd energy level is n=2 3 rd energy level is n=3 3 rd energy level is n=3 4 th energy level is n=4 4 th energy level is n=4 Etc. Etc.

The 1 st energy level has the lowest of energies and is the easiest for electrons to live in (remember, they are lazy!). The 1 st energy level has the lowest of energies and is the easiest for electrons to live in (remember, they are lazy!). But if it is full, they have to go to the 2 nd energy level and so on. But if it is full, they have to go to the 2 nd energy level and so on.

Sublevels The number of sublevels in an energy level is equal to the value of n. The number of sublevels in an energy level is equal to the value of n. 1 st energy level (n=1) has 1 sublevel (1s) 1 st energy level (n=1) has 1 sublevel (1s) 2 nd energy level (n=2) has 2 sublevels (2s, 2p) 2 nd energy level (n=2) has 2 sublevels (2s, 2p)

3 rd energy level (n=3) has 3 sublevels (3s, 3p, 3d) 3 rd energy level (n=3) has 3 sublevels (3s, 3p, 3d) 4 th energy level (n=4) has 4 sublevels (4s, 4p, 4d, 4f) 4 th energy level (n=4) has 4 sublevels (4s, 4p, 4d, 4f) Notice the names of the sublevel are a number (same as n) and a letter (which will have to do with the orbitals) Notice the names of the sublevel are a number (same as n) and a letter (which will have to do with the orbitals)

Orbitals All s sublevels (1s, 2s, 3s, etc), will have 1 orbital All s sublevels (1s, 2s, 3s, etc), will have 1 orbital All p sublevels (2p, 3p, 4p, etc), will have 3 orbitals All p sublevels (2p, 3p, 4p, etc), will have 3 orbitals All d sublevels (3d, 4d, 5d, etc), will have 5 orbitals All d sublevels (3d, 4d, 5d, etc), will have 5 orbitals All f sublevels (4f, 5f, 6f, etc), will have 7 orbtials All f sublevels (4f, 5f, 6f, etc), will have 7 orbtials

Some info about Orbitals s orbitals are spherically shaped and there is only 1 type s orbitals are spherically shaped and there is only 1 type p orbitals are dumbbell shaped and there are 3 types p orbitals are dumbbell shaped and there are 3 types d orbitals are complexly shaped and there are 5 types d orbitals are complexly shaped and there are 5 types f orbitals are VERY complexly shaped and there are 7 types f orbitals are VERY complexly shaped and there are 7 types

Electrons in the Orbitals Each orbital can hold a maximum of 2 electrons
