The electron configuration of arsenic (At) is 4s2 3d10 4p3.
The electron configuration of arsenic allows it to combine in several different valances, including -3, 0, +3 and +5. It combines with other elements, including hydrogen, oxygen, the halogens and sulfur.
Many of these compounds are extremely poisonous. Arsenic (III) oxide, white arsenic is one of the most well-known. In dilute concentrations, too weak to be poisonous, arsenic is a carcinogen, according to Reference.com.
The ground state electron configuration for arsenic (As) is [Ar] 3d10 4s2 4p3. This means that arsenic has 5 electron shells, with two electrons in the 4s orbital, three electrons in the 4p orbital, and ten electrons in the 3d orbital.
To come up with the electron configuration for Arsenic, you first need to count up how many electrons it has (it will be the same as the atomic number since the charge is neutral)... 18. Then you need to follow the aufbui order and work your way up the orbitals filling them in. 1s takes 2electrons, 2s takes 2 electrons, 2p takes 6 electrons, 3s takes 2 electrons, and lastly 3p takes 6 electrons (total of 18). The order of the orbitals and how many electrons each can take you will just need to memorize or learn some tricks to remember.
You can also just take a short cut and ignore all the orbitals before the row Arsenic is on to show ONLY the valence electrons, ie:
[Ne] 3s2 3p6
If you are still having trouble, http://mymcat.com/wiki/Electron_Configuration, has a lot of examples, including your question.
Arsenic is in period 4, so valence electrons will be in 4th shell. It is a p block element, so filling orbitals will be p (4p), and it comes after transition elements, so it will have the 3d orbitals already filled. Thus, it will be [Ar]4s2 3d10 4p3
I believe there are many excited states...and only one ground state. (wrong) 1s22s22p63s23p64s23d104p25s1. just take the last electron in the ground state and bump it up one level....

What represents the electron configuration of a metalloid in the ground state?
A metalloid in the ground state typically has an electron configuration that exhibits characteristics of both metals and nonmetals. For example, arsenic (a metalloid) has an electron configuration of [Ar] 3d10 4s2 4p3 in its ground state. The varying valence electron shells contribute to the unique properties of metalloids.

Is a phosphorus atom in the ground state paramagnetic or diamagnetic?
Arsenic is paramagnetic because the electron configuration is {Ar}4s^2,3d^10,4p^3. Due to the unpaired electron at the end (4p^*3*) the atom in ground state is paramagnetic. **OR Arsenic would be paramagnetic since the 4 p orbitals each contain one electron with parallel spin. These three unpaired electrons give arsenic its paramagnetic property.

How does the ground state electron configuration of the hydrogen atom differ from that of a ground state helium atom?
The ground state electron configuration of hydrogen is 1s^1, meaning it has one electron in the 1s orbital. Helium in its ground state has an electron configuration of 1s^2, indicating it has two electrons in the 1s orbital. So, the main difference is that hydrogen has one electron in its outer shell while helium has two electrons in its outer shell.
Is the electron configuration of sodium an excited state or ground state?
The electron configuration of sodium in its ground state is 1s2 2s2 2p6 3s1. This is not an excited state configuration, as the electrons are in their lowest energy levels available in the atom. Excited states occur when electrons are in higher energy levels than the ground state configuration.
