Krypton. In order to find this you have to look at the periodic table. Imagine the periodic table is divided into three sections, the first two columns, 1A and 2A, the middle section, the transition metals, and the right side, 3A to 7A. The first two columns are the s electrons, the middle section is the d electrons, and the right side is the p electrons (oversimplification). 4s2 4p6 means go to the 4th period (row). two s's and 6 p's. Just count it. the 4th element in the p electrons in the 4th period is Krypton.

No no no Hg is Mercurys Atomic symbol. Once i find the Lewis Dot diagram for mercury, i shall post it ok?
It is very easy. Take a nitrogen atom at center. Draw 5 valence electrons around it (keep two of them in pairs). Now take 3 hydrogen atoms in front of every free electron. Draw the electron of each hydrogen atom. Click Here to see the diagram I have drawn using using MS Paint.

Since arsenic is an element, an arsenic model would just be ne arsenic atom __________________________________________________________ One of the best ways to see how an arsenic model looks like is going to Chemical Elements.com. It'll show the periodic table, and just click on AS and it'll show you.
Electronic configuration of scandium: [Ar]3d1.4s2.
Go to settings and click on change configuration control.There is no other way to change it.
You need to plug in your device and then go to the left hand side and click on device. You will then go to the lefthand side and click on configuration. Open configuration and click on music. From there, select the song or songs and highlight them. you then right click and hit delete. Hth, took me an hour to figure it out.
See at: http://www.webelements.com each element and click after on physical properties.

Go to the start menu, type in mouse and press enter. Then under button configuration, click right handed then click OK
You would have to determine the electron configuration for atoms of a given element. Each s sublevel contains 1 orbital, each p sublevel contains 3 orbitals, each d sublevel contain 5 orbitals, and each f sublevel contains 7 orbitals. Click on the related link to see a periodic table that shows electron configurations for the elements.
