What is longhand electron configuration?

Answer 1

There are many types of rules for electron configuration. Look at the Aufbau principle and Hund's rules.

• In each orbital there is a maximum of two electrons.
• In a "s" orbital, there are two electrons.
• In a "p" orbital, there are three sub-orbitals, each containing two electrons. (Thus containing 6 electrons)
• In a "d" orbital, there are five sub-orbitals, each containing two electrons. (Thus containing 10 electrons)
• In a "f" orbital, there are seven sub-orbitals, each containing two electrons. (Thus containing 14 electrons)

Look at the Aufbau diagram I linked below.

The coefficient represents the orbital. Do not use mathematics to try to solve the configurations.

1s2 2s2 2p6 : Neon's Electron Configuration

The letter following the coefficient describes which type of orbital it is, being s,p,d, or f.

The superscript denotes the number of electrons it contains. If you add 2, 2, and 6, you would get 10, Neon's atomic number.

Answer 3

"Noble gas configuration" means that in writing out an electron configuration for an atom, rather than writing out the occupation of each and every orbital specifically, you instead lump all of the core electrons together and designate it with the symbol of the corresponding noble gas on the Periodic Table (in brackets). For example, the noble gas configuration of nitrogen is [He]2s22p3

Answer 4

example.... as sodium has 11 proton, 11 electron and 12 neutron; you take the number of electron and arrange it so that we can write the electronic configuration. in the first shell the maximum number of electron you can put is 2 and for the rest of the shell its 8 thats why the electronic configuration of sodium is going to be 2:8:1 - 2+8+1 is 11(electron number of sodium)

Answer 5

lets take oxygen as an example. the electron shell configuration of an oxygen atom is 2.6, but it also can be written as 2-6.

hope that helped :D

Answer 6

Configuration for an element (not the abbreviated one with the noble gases)

example:

Ca: 1s2 2s2 2p6 3s2 3p6 4s2
P: 1s2 2s2 2p6 3s2 3p3
Na: 1s2 2s2 2p6 3s1
