What is ground state configuration?
The ground state configuration is the lowest energy, most stable arrangement. An excited state configuration is a higher energy arrangement (it requires energy input to create an excited state).
What is ground state electronic configuration?
The ground state configuration is the lowest energy, most stable arrangement. An excited state configuration is a higher energy arrangement (it requires energy input to create an excited state). Valence electrons are the electrons utilised for bonding.
What is number 14 on the periodic table?

How to calculate electron configuration?
If you want to do manually then follow the steps below to write shorthand electron configurations: First, find the required element on the periodic table. Now, find the atomic number of the first noble gas in the periodic table. Write the noble gas symbol in parentheses to start its electronic configuration. Then, continue writing the electron configuration of a certain element until you reach the correct number of electrons.
What is the electron arrangement for aluminum?
Solution: Aluminum has 13 electrons so it will have the electron arrangement (2, 8, 3) which represents two electrons in the n=1 energy level, eight electrons in the n=2 level, and three electrons in the n=3 level. Aluminum has three valence electrons (indicated by the three electrons in the n=3 level).
How many p-orbitals are occupied in a K atom?
As you can see, the 2p and 3p sublevels each hold six electrons, which means that they are completely occupied. Since every p sublevel has a total of three p-orbitals – px, py, and pz – the number of p-orbitals occupied in a K atom is equal to 6 – 3 p-orbitals on the 2p sublevel and 3 p-orbitals on the 3p sublevel.
How many electrons are in aluminum?
Aluminum has 13 electrons. The atomic number of an element tells us how many protons and electrons are in an atom of that element. Since the atomic number of aluminum is 13, then we know there are 13 positively charged protons as well as 13 negatively charged electrons to balance each other out.
